# Mean, Median, Mode, and Range Worksheets

What Do Mean, Median, and Mode Measure? In statistics, the central tendency is defined as the typical or central value of the probability distribution. Primarily, we have three basic measurements of central tendency, namely, mean, median, and mode. Each of these measurements provides us with valuable information about the data set. We can use this information to how data points are related to each other in the data set. Mean or more commonly known as the average value is calculated by adding all the given data points and dividing them by the numbers of given data points. For example, we have values 20, 15, 10, 25, and 5. To find the mean of these values, we will first add all the values. 20 + 15 +10 + 25 + 5, we will get 75. Then we will divide 75 with the number of given addends, which is 5 in this case. The mean we will get is 75/5 = 15. Median is the number present in the middle of a given data set. That means it has an equal number of data points below and above it. For example, I few take the same data points, 20, 15, 10, 25, and 5. In this case, the median is 10, as it has an equal number of data points both above and below it. The mode tells us the number with the highest frequency that is it occurred the most in a data set. In our example, 20, 15, 10, 25, and 5, each number is present one time only; hence there is no mode in this data set.

• ### Basic Lesson

Introduces the terms mean, median, mode, and range. Provides a detailed example of the use of the terms within a data set. Calculate the mean, median, mode and range for the data set. Data Set: 1, 3, 1, 5, 3, 4, 7, 8, 4, 2 The range is lowest value (1) and highest value (8) in the set.

• ### Intermediate Lesson

This lesson focuses on the use and application of medians within data sets. Find the median of the given data. 2, 3, 5, 2, 4, 6, 7, 9, 12, 11, 12, 13, 15 The given data set is odd (13 numbers). Therefore, if we place the data set in ascending order, the median will be the middle number...

• ### Basic Lesson

Introduces the concepts of Mean, Median, and Mode. Median is value of observation that divides the data distribution into two equal parts i.e. half of observations are above it and half of observations are below it. If the number of observation is even then median is average of n/2 and n/2 + 1.
