Measures Of Central Tendency Worksheet With Answers Pdf
When dealing with data in statistics, it is important to know how to summarize and describe the data. One way to do this is by using measures of central tendency. Measures of central tendency are a way to describe the typical or central values in a set of data. Three common measures of central tendency are the mean, median, and mode. A worksheet on measures of central tendency with answers in PDF format can help students practice their skills in finding these measures.
What is a Measure of Central Tendency?
A measure of central tendency is a summary statistic that represents the center or typical value of a set of data. It can help us describe and understand the data better. The three most common measures of central tendency are the mean, median, and mode.
What is the Mean?
The mean is also known as the arithmetic mean or average. It is calculated by adding up all the values in a set of data and then dividing by the number of values. For example, if we have the following set of data: 5, 10, 15, 20, 25, the mean would be calculated as follows:
(5 + 10 + 15 + 20 + 25) ÷ 5 = 15
The mean is a useful measure of central tendency when the data is normally distributed.
What is the Median?
The median is the middle value in a set of data when the values are arranged in order from smallest to largest. If there is an even number of values, the median is the average of the two middle values. For example, if we have the following set of data: 5, 10, 15, 20, 25, the median would be 15.
The median is a useful measure of central tendency when the data is skewed or when there are extreme values in the data.
What is the Mode?
The mode is the value that occurs most frequently in a set of data. For example, if we have the following set of data: 5, 10, 15, 20, 20, 25, the mode would be 20. It is possible for a set of data to have more than one mode, or no mode at all.
The mode is a useful measure of central tendency when we want to know the most common value in the data.
