Average
The average, also known as the mean, is a measure of central tendency in mathematics
The average, also known as the mean, is a measure of central tendency in mathematics. It is found by adding up all the numbers in a set and then dividing the sum by the total number of values in the set.
To find the average, follow these steps:
1. Add up all the numbers in the set.
2. Count how many numbers are in the set.
3. Divide the sum of the numbers by the count.
For example, let’s find the average of the following set of numbers: 5, 8, 12, 7, 9.
Step 1: Add up the numbers: 5 + 8 + 12 + 7 + 9 = 41.
Step 2: Count the numbers in the set: There are 5 numbers in the set.
Step 3: Divide the sum by the count: 41 ÷ 5 = 8.2.
Therefore, the average of the set is 8.2.
It is important to note that the average can be influenced by outliers, so it may not always represent the typical value. In such cases, it is advisable to consider other measures of central tendency like the median or mode.
