state whether the data is discrete or continuous

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. Both samples are biased. O A. But still, their samples would be, in all likelihood, different from each other. The color of hair can be considered nominal data, as one color cant be compared with another color. Because students can complete only a whole number of hours (no fractions of hours allowed), this data is quantitative discrete. Do you think that either of these samples is representative of (or is characteristic of) the entire 10,000 part-time student population? Then choose every fiftieth name thereafter until you have a total of 400 names (you might have to go back to the beginning of your phone list).

Continuous information is information that falls into a continuous series. Continuous data are in the form of fractional numbers. To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. It is further classified as discrete data and continuous data. The key difference between discrete and continuous data is that discrete data contains the integer or whole number. The number of books in a rack is a finite countable number. The data are discrete because the data can take on any value in an interval. Suppose ABC College has 10,000 part-time students (the population).

Solved State whether the data described below are discrete - Chegg Question: State whether the data described below are discrete or continuous, and explain why. A sample should have the same characteristics as the population it is representing. Nominal and ordinal data can act as both discrete and continuous. Qualitative or Quantitative? Discrete or Continuous? | Ching-Chi Yang Determine the type of sampling used (simple random, stratified, systematic, cluster, or convenience). From that number, count ten quiz scores and record that quiz score. We need to evaluate the statistical studies we read about critically and analyze them before accepting the results of the studies. Qualitative data tells about the perception of people. A discrete variable, on the other hand, can only take on specific values. Quantitative data can be expressed in numerical values, making it countable and including statistical data analysis. For example, if you randomly sample four departments from your college population, the four departments make up the cluster sample. 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. Press MATH. To four decimal places, these numbers are not equivalent. A.The data are continuous because the data can only take on the data can only take on specificvalues.

The first Solved state whether the data is continous or discrete The | Chegg.com Now, suppose we take a third sample. Most statisticians use various methods of random sampling in an attempt to achieve this goal. Examples: crash testing cars or medical testing for rare conditions, Undue influence: collecting data or asking questions in a way that influences the response. The gender of a person, i.e., male, female, or others, is qualitative data. Even if Doreen and Jung used the same sampling method, in all likelihood their samples would be different. Discrete data is data that can only take certain values, while data that can take any value is continuous data. The data are the colors of houses. A histogram is used to graphically represent continuous data. It would be great if you already have a bit of knowledge about a course before opting for it. 1: 23-54 (2012), ssh.dukejournals.org/content/36/1/23.abstract (accessed May 1, 2013).

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. These data consist of audio, images, symbols, or text. Systematic sampling is frequently chosen because it is a simple method. Ungrouped frequency distribution of discrete data is performed against a single value. The data are discrete because the data can only take on specific values. Two positions of an open gate are shown. y's house is at D, 750 feet from the intersection. Using a calculator, random numbers are generated and a student from a particular discipline is selected if he or she has a corresponding number. The areas of the lawns are 144 sq. Complex numbers and fluctuating data values that be measured over a defined time frame are referred to as continuous data. A medical researcher interviews every third cancer patient from a list of cancer patients at a local hospital. the data can only take on specific values . 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). The data she collects are summarized in the pie chart Figure $\PageIndex{1}$. A high school principal polls 50 freshmen, 50 sophomores, 50 juniors, and 50 seniors regarding policy changes for after school activities. 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).

Continuous data represents information that can be divided into smaller levels. Small letters like $x$ or $y$ generally are used to represent data values. When a sampling bias happens, there can be incorrect conclusions drawn about the population that is being studied. The term discrete means distinct or separate. These kinds of data are also known as Numerical data. classes and taking every fifth senior citizen on the list, for a total of ten senior citizens.
