state whether the data is discrete or continuous

If you sample without replacement, then the chance of picking the first person is ten out of 25, and then the chance of picking the second person (who is different) is nine out of 24 (you do not replace the first person). 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. B. Nominal data.Ordinal data.Discrete data.Continuous data. Ra From that number, count ten quiz scores and record that quiz score. The option "B" is correct i.e. . classes and taking every fifth senior citizen on the list, for a total of ten senior citizens. amount of money (in dollars) won playing poker, IQ scores (This may cause some discussion.). This is important to know when we think about what the data are telling us. Also, in both cases, not all students have a chance to be in either sample. Therefore, adjustment of the differential equations system under such data . The amount of money they spend on books is as follows: $128; $87; $173; $116; $130; $204; $147; $189; $93; $153. Continuous data: When numerical data has . The weights of the soups (19 ounces, 14.1 ounces, 19 ounces) are quantitative continuous data because you measure weights as precisely as possible. Hair color, blood type, ethnic group, the car a person drives, and the street a person lives on are examples of qualitative data. It is countable. Great Learning's Blog covers the latest developments and innovations in technology that can be leveraged to build rewarding careers. The two-digit number 14 corresponds to Macierz, 05 corresponds to Cuningham, and 04 corresponds to Cuarismo. The result of the rolling is a dice is 1, 2, 3, 4, 5, 6, 7, and 8. The continuous data can be broken down into fractions and decimals, i.e. The second sample is taken using a list of senior citizens who take P.E. Confounding makes it difficult or impossible to draw valid conclusions about the effect of each factor. according to measurement accuracy, it can be significantly subdivided into smaller sections. It is understandable that it must be making you feel nervous right now but your emotions are valid! Why or why not? Press ENTER. O C. On the other hand, if we count large quantities of any discrete entity. Indicate whether quantitative data are continuous or discrete. This data is so important for us that it becomes important to handle and store it properly, without any error. Press ENTER. Researchers often prefer to use quantitative data over qualitative data because it lends itself more easily to mathematical analysis. Ordinal data have natural ordering where a number is present in some kind of order by their position on the scale. A sample should have the same characteristics as the population it is representing. The data are because.continuous the data can only take on specific values C. a. Weights are quantitative continuous data because weights are measured. Each undergraduate student in the fall semester has the same probability of being chosen at any stage of the sampling process. O A. Sometimes percentages add up to be more than 100% (or less than 100%). 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. ), Education Level (Higher, Secondary, Primary), Total numbers of students present in a class, The total number of players who participated in a competition. data are discrete because the data can take on any value in an These data dont have any meaningful order; their values are distributed into distinct categories. Press ENTER 15 times and record the numbers. The Literary Digest Poll, Virtual Laboratories in Probability and Statistics, Gallup Presidential Election Trial-Heat Trends, 19362008, Gallup Politics. Think about what contributes to making Doreens and Jungs samples different. Zanas house is at A, 500 feet from the intersection, and Tan's house is at B, 750 feet from F. Which distance is longer, the distance from Zana's house to Tan's house or the distance from Theresa's house to Is house? 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. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. There are particular calculators for different statistics exams and having good knowledge about their use and implementation would be great. Continuous data. Quantitative data may be either discrete or continuous. State whether the data described below are discrete or continuous and explain why The amounts of time that different brands' batteries last in a CD player. Whether you are a data scientist, marketer, businessman, data analyst, researcher, or you are in any other profession, you need to play or experiment with raw or structured data. A student interviews classmates in his algebra class to determine how many pairs of jeans a student owns, on the average. If Doreen and Jung took larger samples (i.e. Any group of n individuals is equally likely to be chosen by any other group of n individuals if the simple random sampling technique is used. The list of fruit is nominal. The random numbers 0.94360 and 0.99832 do not contain appropriate two digit numbers. You sample five gyms. What is the type of sampling in each case? A bar graph is appropriate to compare the relative size of the categories. So is the case of statistics too. A pie chart cannot be used. Problems with samples: A sample must be representative of the population. Suppose Doreen and Jung both decide to study the average amount of time students at their college sleep each night. 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). The data are discrete because the data can take on any value in an interval. Instead, we use a sample of the population. Record the quiz scores that correspond to these numbers. You have to be dedicated. For example, if the population is 25 people, the sample is ten, and you are sampling with replacement for any particular sample, then the chance of picking the first person is ten out of 25, and the chance of picking a different second person is nine out of 25 (you replace the first person). We all know that time is very important, it doesnt wait for anyone. The data are continuous because the data can take on any value in an interval. Conduct the survey by sitting in Central Park on a bench and interviewing every person who sits next to you. Tables are a good way of organizing and displaying data. Surely, you can get all the study material on Vedantu mobile app- learn live online. The following pie charts have the Other/Unknown category included (since the percentages must add to 100%). Non-response or refusal of subject to participate: The collected responses may no longer be representative of the population. A histogram is used to graphically represent continuous data. The Other/Unknown category is large compared to some of the other categories (Native American, 0.6%, Pacific Islander 1.0%). B. These 18 quiz scores are a stratified sample. The amount a person grew (in height) in a year. Solution: - Data : The capacities of different hotels. These data are represented mainly by a bar graph, number line, or frequency table. B. Three cell phone towers form APQR. and the Michigan State University Institutional Animal Care and Use Committee prior to the start of data collection. The points are associated with an unbroken line. Your email address will not be published. There are distinct or different values in discrete data. Besides herself, Lisas group will consist of Marcierz, Cuningham, and Cuarismo. c . Number each department, and then choose four different numbers using simple random sampling. Question: State whether the data described below are discrete or continuous, and explain why. B. 2003-2023 Chegg Inc. All rights reserved. Asking all 10,000 students is an almost impossible task. When a sampling bias happens, there can be incorrect conclusions drawn about the population that is being studied. To choose a stratified sample, divide the population into groups called strata and then take a proportionate number from each stratum. A statistics professor collects information about the classification of her students as freshmen, sophomores, juniors, or seniors. Convenience sampling involves using results that are readily available. The land areas of different countries Choose the correct answer below. discrete because the data can only take on specific values . 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. It is classified into two broad categories: qualitative data and quantitative data. To determine the proportion of people taking public transportation to work, survey 20 people in New York City. Cloudflare Ray ID: 7a2992ec2e151da5 Quantitative data can be used for statistical manipulation. The data are discrete because the data can only take on specific values. The data are continuous because the data can only take on specific values. Continuous information is information that falls into a continuous series. In reality, a sample will never be exactly representative of the population so there will always be some sampling error. 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. 3. The data are continuous because the number of classes you take per school year. To do so, the ship must sail between two pairs of islands, avoiding sailing between a third p For qualitative data, if the list can be sorted naturally, we further specify it as an ordinal variable. It may take any numeric value, within a potential value range of finite or infinite. 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. Besides simple random sampling, there are other forms of sampling that involve a chance process for getting the sample. Divide into groups of two, three, or four. These values do not have to be complete numbers, but they are values that are fixed. C. The data are To four decimal places, these numbers are equivalent (0.0999).
