state whether the data is discrete or continuous
. Discrete vs continuous data are two broad categories of numeric variables. Making a schedule/timetable or studying together with your peers may help you in focusing and keep you active. Data that can only take on certain values are discrete data. The durations of a chemical reaction comma repeated . The data are continuous because Samples that contain different individuals result in different data. The data are because.continuous the data can only take on specific values C. Sampling data should be done very carefully. The weights (in tons) of the trees in a forestANSWERA.) Just know that you have prepared and worked hard for this. Required fields are marked *. Asking all 20,000 listeners is an almost impossible task. Qualitative or Categorical Data is data that cant be measured or counted in the form of numbers. The data are continuous because the data can take on any value in an interval. Amount of money, pulse rate, weight, number of people living in your town, and number of students who take statistics are examples of quantitative data. OB. It is classified into two broad categories: qualitative data and quantitative data. The two numbers are for two of the columns. Convenience sampling is a nonrandom method of choosing a sample that often produces biased data. Try this experiment twice. Continuous information is information that falls into a continuous series. The exact distances (in centimeters) between the chairs in a college classroom. Using a calculator, random numbers are generated and a student from a particular discipline is selected if he or she has a corresponding number. Books for these classes tend to be expensive. Suppose we take two different samples. However, generally, we use age as a discrete, NCERT Solutions for Class 12 Business Studies, NCERT Solutions for Class 11 Business Studies, NCERT Solutions for Class 10 Social Science, NCERT Solutions for Class 9 Social Science, NCERT Solutions for Class 8 Social Science, CBSE Previous Year Question Papers Class 12, CBSE Previous Year Question Papers Class 10. Measurements of the amount of beverage in a 16-ounce can may vary because different people make the measurements or because the exact amount, 16 ounces of liquid, was not put into the cans. Data are individual items of information that come from a population or sample. O A. OC. the data can only take on specific values . Many other courses are available online to master your foundational knowledge which may assist you later. according to measurement accuracy, it can be significantly subdivided into smaller sections. Surveys mailed to households and then returned may be very biased (they may favor a certain group). Starting with that student, every 50th student is chosen until 75 students are included in the sample. Record the number of ones, twos, threes, fours, fives, and sixes you get in the following table (frequency is the number of times a particular face of the die occurs): Did the two experiments have the same results? the chance of picking the first person for any particular sample is 1000 out of 10,000 (0.1000); the chance of picking a different second person is 999 out of 9,999 (0.0999); you do not replace the first person before picking the next person. feet, 180 sq. You go to the supermarket and purchase three cans of soup (19 ounces) tomato bisque, 14.1 ounces lentil, and 19 ounces Italian wedding), two packages of nuts (walnuts and peanuts), four different kinds of vegetable (broccoli, cauliflower, spinach, and carrots), and two desserts (16 ounces Cherry Garcia ice cream and two pounds (32 ounces chocolate chip cookies). This is important to know when we think about what the data are telling us. ), Education Level (Higher, Secondary, Primary), Total numbers of students present in a class, The total number of players who participated in a competition. ), Ranking of people in a competition (First, Second, Third, etc. The data are continuous because the data can only take on specific values. It would be great if you already have a bit of knowledge about a course before opting for it. Therefore, adjustment of the differential equations system under such data . the number of classes you take per school year. This data is so important for us that it becomes important to handle and store it properly, without any error. Both samples are biased. Record the number. This particular bar graph in Figure \(\PageIndex{4}\) can be difficult to understand visually. B. The following graph is the same as the previous graph but the Other/Unknown percent (9.6%) has been included. Compare the fractions 9/25 and 9/24. They both did. Besides the chemistry course, some of them are also taking first-term calculus. Continuous data. Sometimes percentages add up to be more than 100% (or less than 100%). Results are the outcome of our efforts and if you believe that you have put your best, then you will surely be able to score good marks. When you have a numeric variable, you need to determine whether it is discrete or continuous. The volume of cola in a can is 11.8 oz. For example, call-in surveys are invariably biased, because people choose to respond or not. Often, people with strong positive or negative opinions may answer surveys, which can affect the results. B. Q: State whether the data below are discrete or continuous, explain why. O C. C. Divide your college faculty by department. discrete because the data can only take on specific values .

It answers the questions like how much, how many, and how often. For example, the price of a phone, the computers ram, the height or weight of a person, etc., falls under quantitative data. They spend: $50; $40; $36; $15; $50; $100; $40; $53; $22; $22. This table displays six sets of quiz scores (each quiz counts 10 points) for an elementary statistics class. The tables display counts (frequencies) and percentages or proportions (relative frequencies). feet, and 210 sq. State whether the data described below are discrete or continuous, and explain why The speeds of the different people walking in a park Choose the correct answer below. Doreen's sample will be different from Jung's sample. Press 5:randInt( and enter 1,6). All data that are the result of counting are called quantitative discrete data. This data helps market researchers understand the customers tastes and then design their ideas and strategies accordingly. For the purpose of analysis, data are presented as the facts and figures collected together. State whether the data described below are discrete or continuous, and explain why. How to differentiate the obtained results as discrete and continuous data? Quantitative data are always numbers. If you count the number of phone calls you receive for each day of the week, you might get values such as zero, one, two, or three. Ans: Ducks in a pond are discrete data because the number of ducks is a finite number. Step One: Master the Foundational Knowledge. Now business runs on data, and most companies use data for their insights to create and launch campaigns, design strategies, launch products and services or try out different things. The distance from G to H in In statistics, a sampling bias is created when a sample is collected from a population and some members of the population are not as likely to be chosen as others (remember, each member of the population should have an equally likely chance of being chosen). A study is done to determine the average tuition that San Jose State undergraduate students pay per semester. Sleep deprivation is of no use, instead, you should take a nap to relax the nerves of your brain in order to learn and study later. The data are discrete because the data can take on any value in an interval. When a car is randomly selected, it is found to have 3 wipers. To determine the proportion of people taking public transportation to work, survey 20 people in New York City. Press 5:randInt( and enter 1, 60). In today's changing times, pursuing a career in this subject is known to provide some of the most sought professional options. (2012), D is the discrete character data, z is a particular character mapping, and are the parameters of the hOUwie model.

QUESTIONState whether the data described below are discrete or continuous, and explain why. If you and your friends carry backpacks with books in them to school, the numbers of books in the backpacks are discrete data and the weights of the backpacks are continuous data. LBCC Distance Learning (DL) program data in 2010-2011. lastbaldeagle. Nominal and ordinal data can act as both discrete and continuous. For example, if you randomly sample four departments from your college population, the four departments make up the cluster sample. For example, the sample may not be large enough. The list of fruit is nominal. b. The Other/Unknown category is large compared to some of the other categories (Native American, 0.6%, Pacific Islander 1.0%). Confounding: When the effects of multiple factors on a response cannot be separated. You count discrete data. The use of discrete and continuous quantitative variables would be helpful for detecting intervention effects . Quantitative data can be used for statistical manipulation. Performance & security by Cloudflare. Statistics involves organizing, analyzing, interpreting, and representing data. State whether the data described below are discrete or? The ordinal data only shows the sequences and cannot use for statistical analysis. The data are continuous because the data can take on any value in an interval. In the graph, the percentages add to more than 100% because students can be in more than one category. If she needed to, Lisa could have generated more random numbers. Data is classified into 4 types. 10. Those 100 students are the sample. Non-response or refusal of subject to participate: The collected responses may no longer be representative of the population. data are discrete because the data can take on any value in an On your calculator, press Math and arrow over to PRB. But still, their samples would be, in all likelihood, different from each other. Then use simple random sampling to choose proportionate numbers from the first department and do the same for each of the remaining departments. Continuous Data Examples: Measurement of height and weight of a student, Daily temperature measurement of a place, Wind speed measured daily, etc. Still, continuous data stores the fractional numbers to record different types of data such as temperature, height, width, time, speed, etc. To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. 4. c. Statistics and Probability questions and answers, state whether the data is continous or discrete The durations of The percent columns make comparing the same categories in the colleges easier. Over time, some continuous data can change. and the Michigan State University Institutional Animal Care and Use Committee prior to the start of data collection. The actual process of sampling causes sampling errors. B. It includes only those values which are separate and can only be counted in, , which means that the data can not be split into, Continuous data is the data that can be of any value. a. stratified; b. cluster; c. stratified; d. systematic; e. simple random; f.convenience. Notice that backpacks carrying three books can have different weights. You will learn why when you study confidence intervals. State whether the data described below are discrete or continuous, and explain why. answer below. Convenience sampling involves using results that are readily available. B.The data are discrete because the data can only take on specific values. For example, the number of desks in an office, the number of times a dice is rolled, the number of telephone calls received, etc. The numbers of hotels in cities Choose the correct answer below. answer below. Instead of that, just revise what youve already done. Sampling without replacement instead of sampling with replacement becomes a mathematical issue only when the population is small. Two students carry three books, one student carries four books, one student carries two books, and one student carries one book. Compare the fractions 999/10,000 and 999/9,999. Think about what contributes to making Doreens and Jungs samples different. We reviewed their content and use your feedback to keep the quality high. Note: randInt(0, 30, 3) will generate 3 random numbers. What type of data is this? Over time, some continuous data can change. The data are continuous because the data can take We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Discrete data is a sort of numerical data that consists of full, concrete numbers that have particular and fixed data values that are determined by counting. We are interested in the average amount of money a part-time student spends on books in the fall term. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. In this situation, create a bar graph and not a pie chart.

Difference Between Continuous and Discrete Data, Questions on Discrete Data Continuous Data. For these samples, each member of the population did not have an equally likely chance of being chosen. , i.e. When a sampling bias happens, there can be incorrect conclusions drawn about the population that is being studied. The continuous variable can take any value within a range. However the third random number, 0.14669, contains 14 (the fourth random number also contains 14), the fifth random number contains 05, and the seventh random number contains 04. Is the study impartial? Discrete data. What can you conclude about the angles opposite these sides? Pick three quiz scores randomly from each column. These data cant be broken into decimal or fraction values. Have some sleep, its important. Causality: A relationship between two variables does not mean that one causes the other to occur. We might make different choices of what we think is the best graph depending on the data and the context. The continuous data can be broken down into fractions and decimals, i.e. Look at Figures \(\PageIndex{3}\) and \(\PageIndex{4}\) and determine which graph (pie or bar) you think displays the comparisons better. A high school educational researcher interviews 50 high school female teachers and 50 high school male teachers. Experts are tested by Chegg as specialists in their subject area. Suppose ABC College has 10,000 part-time students (the population). The easiest method to describe is called a simple random sample. Now, suppose we take a third sample. QUESTIONState whether the data described below are discrete or continuous, and explain why. The number of animals in a zoo is continuous data because the number of animals varies yearly depending on the reproduction of new animals or the arrival of new animals. If you did the experiment a third time, do you expect the results to be identical to the first or second experiment? You can go for a business analyst or a statistician or a financial analyst or even an economist etc. Types of soups, nuts, vegetables and desserts are qualitative data because they are categorical. c. The data are continuous because the data can take on any value in an interval. Manufacturers regularly run tests to determine if the amount of beverage in a 16-ounce can falls within the desired range. State whether the data described below are discrete or continuous, and explain why. B. The data he collects are summarized in the histogram. The data are discrete because the data can only take on specific values. A. As a rule, the larger the sample, the smaller the sampling error. According to a report, today, at least 2.5 quintillion bytes of data are produced per day. Collecting data carelessly can have devastating results. The data are continuous because the data can only take on specific values. pair starts due east and then turns 50 toward north. The data . 2. Quantitative data, on the other hand, is one that contains numerical values and uses a scope. Click to reveal Another example is learning how to use calculators. Then survey every U.S. congressman in the cluster.
