The type of data that has clear spaces between values is discrete data. 5. Nominal data.Ordinal data.Discrete data.Continuous data. From that number, count ten quiz scores and record that quiz score. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Statistics and Probability questions and answers, CS State whether the data described below are discrete or continuous, and explain why. The triangles show the position of the gate in relation to its closed position. Data are individual items of information that come from a population or sample. The sample probably doesnt represent the entire fan base and is probably biased towards people who would prefer music. If quantitative, state whether it's discrete or continuous. For example, suppose you have to do a phone survey. The action you just performed triggered the security solution. Blood type might be AB+, O-, or B+. It is further classified as discrete data and continuous data. The percent columns make comparing the same categories in the colleges easier. 2013. Those 100 students are the sample. The second sample is a group of senior citizens who are, more than likely, taking courses for health and interest. Self-selected samples: Responses only by people who choose to respond, such as call-in surveys, are often unreliable. The safest route is to avoid the closest pair of islands. The data are because.continuous the data can only take on specific values C. Doreen uses systematic sampling and Jung uses cluster sampling. Still, continuous data stores the fractional numbers to record different types of data such as temperature, height, width, time, speed, etc. If the survey is done well, the answer is yes. The continuous data can be broken down into. This site is using cookies under cookie policy . This section will describe a few of the most common methods. If you're asked whether age is a continuous or discrete variable in an Introductory Statistics class, the correct answer is technically continuous. 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. In this situation, create a bar graph and not a pie chart. State whether the data described below are discrete or continuous, and explain why. On Tax Day, House to Call for Firing Federal Workers Who Owe Back Taxes. Confounding: When the effects of multiple factors on a response cannot be separated. The data are continuous because the data can take on any value in an interval. These types of data are sorted by category, not by number.

A statistics professor collects information about the classification of her students as freshmen, sophomores, juniors, or seniors. Ordinal data have natural ordering where a number is present in some kind of order by their position on the scale. 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. The data are continuous because the data can only take on specific values . C. Create a simple random sample of 15 quiz scores.

A medical researcher interviews every third cancer patient from a list of cancer patients at a local hospital. 2003-2023 Chegg Inc. All rights reserved. Show how you know. Examples of discrete variables are the number of students and age. The measure of Ris 5 greater than the measure of ZO. answer below. You are going to use the random number generator to generate different types of samples from the data. You can go for a business analyst or a statistician or a financial analyst or even an economist etc. One-third of a number when decreased by 2 equals one-fifth of the nimenbe Find the number. There are a number of options if you go for the statistics degree. You sample five students. Nominal Data is used to label variables without any order or quantitative value. Samples that contain different individuals result in different data. This is important to know when we think about what the data are telling us. Suppose Doreen and Jung both decide to study the average amount of time students at their college sleep each night. For example, 16-ounce cans of beverage may contain more or less than 16 ounces of liquid. The data are discrete because the data can only take on specific values.

Quantitative data may be either discrete or continuous. B. Work collaboratively to determine the correct data type (quantitative or qualitative). . A high school principal polls 50 freshmen, 50 sophomores, 50 juniors, and 50 seniors regarding policy changes for after school activities. If they are not, discuss the reasons. Press 5:randInt( and enter 1, 60). This pie chart shows the students in each year, which is qualitative data. The first sample probably consists of science-oriented students. where n is the number of tips in the phylogeny ( ) , P is the continuous trait value of each species, and Q is the expected value of each species given the continuous trait model calculated following Equation (11) of Beaulieu et al. The two-digit number 14 corresponds to Macierz, 05 corresponds to Cuningham, and 04 corresponds to Cuarismo. Suppose ABC College has 10,000 part-time students (the population). The first The students spend the following amounts: $180; $50; $150; $85; $260; $75; $180; $200; $200; $150. Your instructor will give each group one six-sided die. All data that are the result of counting are called quantitative discrete data. (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.) c . A stated earlier, Lengths are in general, continuous variables. C. The data are Also, in both cases, not all students have a chance to be in either sample. Number the population 120,000 and then use a simple random sample to pick a number that represents the first name in the sample. Non-response or refusal of subject to participate: The collected responses may no longer be representative of the population. Required fields are marked *. It includes only those values which are separate and can only be counted in whole numbers or integers, which means that the data can not be split into fractions or decimals. Please include what you were doing when this page came up and the Cloudflare Ray ID found at the bottom of this page. 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. the data can only take on specific values . Ra It is classified into two broad categories: qualitative data and quantitative data. The data are continuous because the data can take on any value in an interval. Suppose we take two different samples. The data are discrete because the data can . The road from A to E and the road from C and D are perpendicular and intersect at point F. Theresa's house is at C, 500 feet from the intersection. The durations of a chemical reaction comma repeated . 4. State whether the data described below are discrete or continuous, and explain why. 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). You sample five gyms. A pollster interviews all human resource personnel in five different high tech companies. A student interviews classmates in his algebra class to determine how many pairs of jeans a student owns, on the average. Nominal Data is used to label variables without any order or quantitative value. Two positions of an open gate are shown. 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. Determine the type of sampling used (simple random, stratified, systematic, cluster, or convenience). 2003-2023 Chegg Inc. All rights reserved.
