Mean Tutorial What is the Mean?
The mean, often referred to as the average, is a measure of central tendency that is calculated by adding up all the values in a dataset and then dividing by the number of values. It provides a useful summary of a dataset and is widely used in various fields including mathematics, statistics, finance, and everyday life.
How to Calculate the Mean
To calculate the mean of a set of numbers, follow these simple steps:
- Sum all the values: Add up all the numbers in your dataset.
- Count the values: Determine the number of values in your dataset.
- Divide the sum by the count: Divide the total sum by the number of values to get the mean.
Mean Formula
\(\text{Mean} = \frac{\sum \text{Values}}{\text{Number of Values}} \)
Example Calculation
Consider the dataset: 5, 8, 12, 20, 15
- Sum of values: 5+8+12+20+15=605 + 8 + 12 + 20 + 15 = 605+8+12+20+15=60
- Number of values: 5
- Mean: 605 = 12 \(\dfrac{60}{5}\) = 12
