state whether the data is discrete or continuous

Examples of discrete variables are the number of students and age. Is the study impartial? All data that are the result of measuring are quantitative continuous data assuming that we can measure accurately. The data are discrete because the data can . a. stratified; b. systematic; c. simple random; d. cluster; e. convenience. In polling, samples that are from 1,200 to 1,500 observations are considered large enough and good enough if the survey is random and is well done. Your instructor will give each group one six-sided die. Which experiment had the correct results? In other words, each sample of the same size has an equal chance of being selected. Try to identify additional data sets in this example. 2003-2023 Chegg Inc. All rights reserved. Rational Numbers Between Two Rational Numbers, XXXVII Roman Numeral - Conversion, Rules, Uses, and FAQs, Find Best Teacher for Online Tuition on Vedantu. 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. Convenience sampling is a nonrandom method of choosing a sample that often produces biased data. To choose a simple random sample from each department, number each member of the first department, number each member of the second department, and do the same for the remaining departments. State whether the data described below are discrete or continuous, and explain why. feet, and 210 sq. 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. Your answer is correct. The number of books in a rack is a finite countable number. B. O C. The data are continuous because the data can take on any value in an interval. The data are discrete because the data can only take on specific values. a. stratified; b. cluster; c. stratified; d. systematic; e. simple random; f.convenience. Notice that the frequencies do not add up to the total number of students. and it is subdivided into nominal and ordinal data. A. 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. You sample five students. The data are discrete because the data can only take on specific values. There are a number of options if you go for the statistics degree. feet. The gender of a person, i.e., male, female, or others, is qualitative data. Create a cluster sample by picking two of the columns. Discrete vs. Continuous Data: Differences & Examples The size of a sample (often called the number of observations) is important. QUESTIONState whether the data described below are discrete or continuous, and explain why. Data that can only take on certain values are discrete data. and the Michigan State University Institutional Animal Care and Use Committee prior to the start of data collection. However, if two or more of you are taking the same data and get very different results, it is time for you and the others to reevaluate your data-taking methods and your accuracy. Many other courses are available online to master your foundational knowledge which may assist you later. To choose a systematic sample, randomly select a starting point and take every nth piece of data from a listing of the population. These types of data are sorted by category, not by number. Which pair is farther from camp? 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? State whether the data described below are discrete or? continuous, and Do you think that either of these samples is representative of (or is characteristic of) the entire 10,000 part-time student population? ), Marital status (Single, Widowed, Married), When companies ask for feedback, experience, or satisfaction on a scale of 1 to 10, Letter grades in the exam (A, B, C, D, etc. 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. A stated earlier, Lengths are in general, continuous variables. Quantitative data may be either discrete or continuous. Sample size issues: Samples that are too small may be unreliable. 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). Quantitative data are always numbers. 1.2: Variables and Types of Data - Statistics LibreTexts A. Also, the sample represents only those who showed up to the event earlier than the majority. As a rule, the larger the sample, the smaller the sampling error. 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. To do so, the ship must sail between two pairs of islands, avoiding sailing between a third p Can I get some help? Data that can take a decimal value and can vary across a range is called . Show how you know. O A. Record these numbers. The two numbers are for two of the columns. This is important to know when we think about what the data are telling us. When you analyze data, it is important to be aware of sampling errors and nonsampling errors. 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. The students spend the following amounts: $180; $50; $150; $85; $260; $75; $180; $200; $200; $150. Starting with that student, every 50th student is chosen until 75 students are included in the sample. Notice how much larger the percentage for part-time students at Foothill College is compared to De Anza College. The numbers of hotels in cities Choose the correct answer below.

a 4-year educational institution. Number of bacteria in a petri dish is 12,120. 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). Samples of only a few hundred observations, or even smaller, are sufficient for many purposes. All students in those two years are in the sample. Ducks in a pond are discrete data because the number of ducks is a finite number. The data are discrete because the data can take on any value in an interval. The data are the number of books students carry in their backpacks. Three cell phone towers form APQR. Work collaboratively to determine the correct data type (quantitative or qualitative). The percent columns make comparing the same categories in the colleges easier. B. categorical, quantitative discrete or quantitative continuous. These kinds of data can be considered in-between qualitative and quantitative data. 5. Explain your reasoning. Therefore this is discrete data. By using simple random sampling, select states to be part of the cluster.

Quantitative data are the result of counting or measuring attributes of a population. LCM of 3 and 4, and How to Find Least Common Multiple, What is Simple Interest? The discrete data are countable and have finite values; their subdivision is not possible. If the survey is done well, the answer is yes. Conduct the survey by sitting in Central Park on a bench and interviewing every person who sits next to you. Nominal and ordinal data can act as both discrete and continuous. Factors not related to the sampling process cause nonsampling errors. Besides the chemistry course, some of them are also taking first-term calculus. It is not possible to measure qualitative data in terms of numbers and it is subdivided into nominal and ordinal data. These kinds of data are also known as Numerical data. The volumes left parenthesis in cubic feet right parenthesis of different rooms Choose the correct answer below. Causality: A relationship between two variables does not mean that one causes the other to occur. State whether the data described below are discrete or continuous, and explain why: . Working on data is crucial because we need to figure out what kind of data it is and how to use it to get valuable output out of it. Create a stratified sample by column. Indicate whether quantitative data are continuous or discrete. C. State whether the data described below are discrete or continuous, and explain why. 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 quiz scores (20 of them) in these 2 columns are the cluster sample. The numbers of books (three, four, two, and one) are the quantitative discrete data. Solved state whether the data is continous or discrete The | Chegg.com Solved State whether the data described below are discrete - Chegg 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. Create a systematic sample of 12 quiz scores. 1. pair starts due east and then turns 50 toward north. Sampling without replacement instead of sampling with replacement becomes a mathematical issue only when the population is small. The second sample is taken using a list of senior citizens who take P.E. To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. the data can only take on specific values . 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. We all know that time is very important, it doesnt wait for anyone. Opinion poll posted online at: www.youpolls.com/details.aspx?id=12328 (accessed May 1, 2013). The data are because.continuous the data can take on any value in an interval B. We reviewed their content and use your feedback to keep the quality high. The data are discrete because the data can only take on specific values. Experts are tested by Chegg as specialists in their subject area. You can specify conditions of storing and accessing cookies in your browser. The freshman, sophomore, junior, and senior years are numbered one, two, three, and four, respectively. A completely random method is used to select 75 students. b. Instead, we use a sample of the population. Note: randInt(0, 30, 3) will generate 3 random numbers. 13. In this situation, create a bar graph and not a pie chart. Each random number may only contribute one class member. This section will describe a few of the most common methods. Discrete and Continuous Data - Definitions, Examples - VEDANTU The safest route is to avoid the closest pair of islands.
