How to Find Mean

To find the mean of a set of numbers, follow these steps:

  1. Step 1: Add up all the numbers. Start by adding up all the numbers in the set.

  2. Step 2: Count the number of data points. Determine the total count of data points in the set.

  3. Step 3: Divide the sum by the count. Divide the sum of the numbers by the total count to calculate the mean.

  4. Step 4: Round if necessary. Round off the mean to the desired decimal place, if required.

Example:

Let’s find the mean of the following data set: 5, 7, 9, 12, 15

  1. Add up the numbers: 5 + 7 + 9 + 12 + 15 = 48

  2. Count the data points: There are 5 data points.

  3. Divide the sum by the count: 48 ÷ 5 = 9.6

  4. The mean of the data set is 9.6.

Make sure to double-check your calculations and follow the steps accurately to find the mean correctly. Remember, the mean represents the average value of a set of numbers.
