The amount of money they spend on books is as follows: $128; $87; $173; $116; $130; $204; $147; $189; $93; $153. The sample probably doesnt represent the entire fan base and is probably biased towards people who would prefer music. A student interviews classmates in his algebra class to determine how many pairs of jeans a student owns, on the average. The data are continuous because the data can only take on specific values. 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. This variability in samples cannot be stressed enough. QUESTIONState whether the data described below are discrete or continuous, and explain why. Question: CS State whether the data described below are discrete or continuous, and explain why. Continuous data is the data that can be of any value. the chance of picking the first person is 1,000 out of 10,000 (0.1000); the chance of picking a different second person for this sample is 999 out of 10,000 (0.0999); the chance of picking the same person again is 1 out of 10,000 (very low). Create a cluster sample by picking two of the columns. Also read: 22 Top Data Science Books Learn Data Science Like an Expert. The data are the colors of houses. O B. The bar graph is used to graphically represent discrete data. Data is classified into 4 types. You may wrap around (go back to the beginning). A. Examples are lengths, temperature, etc. State whether the data described below are discrete or continuous, and explain why. According to a report, today, at least 2.5 quintillion bytes of data are produced per day. It is a good idea to look at a variety of graphs to see which is the most helpful in displaying the data. Measuring angles in radians might result in such numbers as \(\frac{\pi}{6}\), \(\frac{\pi}{3}\), \(\frac{\pi}{2}\), \(\pi\), \(\frac{3\pi}{4}\), and so on. First, we use convenience sampling and survey ten students from a first term organic chemistry class. In other words, each sample of the same size has an equal chance of being selected. four children shared a two third liter bottle of drink equal.how much did each child drink , two pairs of hikers leave the same camp heading in opposite divections. From that number, count ten quiz scores and record that quiz score. O A. What type of data is this? The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. A type of sampling that is non-random is convenience sampling. B. A local radio station has a fan base of 20,000 listeners. OD. You sample five houses. The land areas of different countries Choose the correct answer below. There are no strict rules concerning which graphs to use. Work collaboratively to determine the correct data type (quantitative or qualitative). and it is subdivided into nominal and ordinal data. If she needed to, Lisa could have generated more random numbers. Again, you sample the same five students. Displaying percentages along with the numbers is often helpful, but it is particularly important when comparing sets of data that do not have the same totals, such as the total enrollments for both colleges in this example. The volume of cola in a can is 11.8 oz. We choose ten different part-time students from the disciplines of chemistry, math, English, psychology, sociology, history, nursing, physical education, art, and early childhood development. There are a number of options if you go for the statistics degree. Besides the chemistry course, some of them are also taking first-term calculus. The option "B" is correct i.e. Every value within a range is included in continuous data. A.The data are continuous because the data can only take on the data can only take on specificvalues. The data are continuous because the data can take on any value in an interval. Discrete data: When numerical data has values that are countable and specific to a particular category, it is called discrete data. You count discrete data. The quiz scores (20 of them) in these 2 columns are the cluster sample. The numbers of programs installed on various computers ANSWERA.) the data can only take on specific values . Tips and Tricks to study Discrete and Continuous Data, Age is discrete data because we could be infinitely precise and use an infinite number of decimal places, rendering age continuous as a result. Log on to our website and explore courses delivered by industry experts. The Pareto chart has the bars sorted from largest to smallest and is easier to read and interpret. Items a, e, f, k, and l are quantitative discrete; items d, j, and n are quantitative continuous; items b, c, g, h, i, and m are qualitative. The numbers of majors offered by colleges Choose the correct answer below. Self-funded or self-interest studies: A study performed by a person or organization in order to support their claim. This data is so important for us that it becomes important to handle and store it properly, without any error. 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. They both did. It may take any numeric value, within a potential value range of finite or infinite. It is not possible to measure qualitative data in terms of numbers and it is subdivided into nominal and ordinal data. For some students, it might feel difficult as it involves logical thinking and mathematics but its a great option for those who love solving and putting their minds all into logic. amount of money (in dollars) won playing poker, IQ scores (This may cause some discussion.). 24 people said theyd prefer more talk shows, and 176 people said theyd prefer more music. These values do not have to be complete numbers, but they are values that are fixed. A. The ordinal data only shows the sequences and cannot use for statistical analysis. That is, a member of the population may be chosen only once. You sample five houses. These data are used for observation like customer satisfaction, happiness, etc., but we cant do any arithmetical tasks on them. Then survey every U.S. congressman in the cluster. However, in the real world age is often treated as a discrete variable because it makes more sense when collecting data and when reporting the results of a study. In this situation, create a bar graph and not a pie chart. Performance & security by Cloudflare. The use of discrete and continuous quantitative variables would be helpful for detecting intervention effects . Numeric variables represent characteristics that you can express as numbers rather than descriptive language. Since this is the case, sampling without replacement is approximately the same as sampling with replacement because the chance of picking the same individual more than once with replacement is very low. 5. We may prefer not to think of 10,00,100 and 10,00,102 as crucially different values, but instead as nearby points on an approximate continuum. Convenience sampling involves using results that are readily available. All the members from these clusters are in the cluster sample. 1.2.13 State whether the data described below are discrete or continuous and explain why.The times required by students to complete a statistics test Choose the correct answer below. The height of a student from age 5-15 is continuous data because the height varies continuously from age 5-15 which is not a constant for 10 years. Press 5:randInt( and enter 1,6). Opinion poll posted online at: www.youpolls.com/details.aspx?id=12328 (accessed May 1, 2013). For instance, hair color might be black, dark brown, light brown, blonde, gray, or red. Indicate whether quantitative data are continuous or discrete. . Procrastination isnt even the last option if you are preparing for a statistics exam. To find out the most popular cereal among young people under the age of ten, stand outside a large supermarket for three hours and speak to every twentieth child under age ten who enters the supermarket. However, generally, we use age as a discrete variable. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Confounding: When the effects of multiple factors on a response cannot be separated. You can also visit their website. Number each department, and then choose four different numbers using simple random sampling. Blood type might be AB+, O-, or B+. It is not possible to measure qualitative data in terms of numbers and it is subdivided into nominal and ordinal data. Quantitative data are the result of counting or measuring attributes of a population. the type of car you drive. Indicate whether quantitative data are continuous or discrete. It can be the version of an android phone, the height of a person, the length of an object, etc. Your instructor will give each group one six-sided die. Biased samples that are not representative of the population give results that are inaccurate and not valid. It is countable. To do so, the ship must sail between two pairs of islands, avoiding sailing between a third p . the distance it is from your home to the nearest grocery store. It is classified into two broad categories: qualitative data and quantitative data. Press ENTER. Even if Doreen and Jung used the same sampling method, in all likelihood their samples would be different. Just as there is variation in data, there is variation in samples. That is, once a member is picked, that member goes back into the population and thus may be chosen more than once. Record the three quiz scores in column one that correspond to these three numbers.

Your email address will not be published. Now, suppose we take a third sample. To four decimal places, these numbers are not equivalent. A sample of 100 undergraduate San Jose State students is taken by organizing the students names by classification (freshman, sophomore, junior, or senior), and then selecting 25 students from each. (We assume that these are the only disciplines in which part-time students at ABC College are enrolled and that an equal number of part-time students are enrolled in each of the disciplines.) When a sampling bias happens, there can be incorrect conclusions drawn about the population that is being studied. Sample size issues: Samples that are too small may be unreliable. 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 histogram is used to graphically represent continuous data. The data are the areas of lawns in square feet. This section will describe a few of the most common methods. These kinds of data can be considered in-between qualitative and quantitative data. Press MATH. You will learn why when you study confidence intervals. For these samples, each member of the population did not have an equally likely chance of being chosen. feet, 190 sq. 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. A random number generator is used to pick two of those years. Discrete is data that can take only certain values. The numbers of hotels in cities Choose the correct answer below. The percent columns make comparing the same categories in the colleges easier. We might make different choices of what we think is the best graph depending on the data and the context. Look at Figures \(\PageIndex{3}\) and \(\PageIndex{4}\) and determine which graph (pie or bar) you think displays the comparisons better. Researchers often prefer to use quantitative data over qualitative data because it lends itself more easily to mathematical analysis. Lisa reads two-digit groups until she has chosen three class members (that is, she reads 0.94360 as the groups 94, 43, 36, 60). Those numbers picked from the first department, picked from the second department, and so on represent the members who make up the stratified sample. Each random number may only contribute one class member. What type of data is this? There are distinct or different values in discrete data. 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. Factors not related to the sampling process cause nonsampling errors. The second pair starts due west and then turns 40 toward south. Try to identify additional data sets in this example. The time(in minutes) it takes The time(in minutes) it takes A: It is given that the time (in minutes) it takes different students to drive to school from home. Most samples are taken from large populations and the sample tends to be small in comparison to the population. If you feel tired at the moment, even that too is fine. Surely, you can get all the study material on Vedantu mobile app- learn live online. Samples of only a few hundred observations, or even smaller, are sufficient for many purposes. Determine whether the data described below are qualitative or quantitative and explain why: . Quantitative data are always numbers. Discrete data. Two students carry three books, one student carries four books, one student carries two books, and one student carries one book. It is further classified as discrete data and continuous data. Quick Check Introduction to Data Science. Sampling without replacement instead of sampling with replacement becomes a mathematical issue only when the population is small. The data are continuous because the data can take on any value in an interval. Data may be classified as qualitative, quantitative continuous, or quantitative discrete. However, students shall understand that it is important for them to recognize their interests and based on that, select the best career path possible. Our choice also depends on what we are using the data for. b. Determine whether the value is from a discrete or continuous It is from a discrete data set because the number of possible values is infinite and countable. The random numbers 0.94360 and 0.99832 do not contain appropriate two digit numbers. B.The data are discrete because the data can only take on specific values. Other well-known random sampling methods are the stratified sample, the cluster sample, and the systematic sample. . A high school educational researcher interviews 50 high school female teachers and 50 high school male teachers. The gender of a person, i.e., male, female, or others, is qualitative data. Press ENTER 15 times and record the numbers. 1. Record the quiz scores that correspond to these numbers. Statistics involves organizing, analyzing, interpreting, and representing data. . The data are because.continuous the data can take on any value in an interval B. For the purpose of analysis, data are presented as the facts and figures collected together. The data are the weights of backpacks with books in them. Causality: A relationship between two variables does not mean that one causes the other to occur. B. State whether the data described below are discrete or continuous and explain why The amounts of time that different - Answered by a verified Tutor . If we were to examine two samples representing the same population, even if we used random sampling methods for the samples, they would not be exactly the same. You sample five gyms.
