The mean (or average) of a dataset is calculated by adding up all the values in the dataset and then dividing by the number of values.
Here's the formula for the mean:
\[ \text{Mean} = \frac{\sum_{i=1}^{n} x_i}{n} \]
Where:
- \(x_i\) represents each value in the dataset
- \(n\) is the number of values in the dataset
- \(\sum\) denotes the summation of all values
Steps to Calculate the Mean:
- Sum all the values: Add all the numbers together.
- Count the values: Determine the number of values in the dataset.
- Divide the sum by the count: Use the formula to compute the mean.
Example:
Consider the dataset: 4, 8, 6, 5, 3.
- Sum: \(4 + 8 + 6 + 5 + 3 = 26\)
- Count: There are 5 numbers.
- Mean: \(\frac{26}{5} = 5.2\)
So, the mean of the dataset is 5.2.
If you have specific data you'd like to calculate the mean for, please provide the values!
