Calculate variance and standard deviation of the following data : 10 , 12 , 8 , 14 , 16 .

Explanation

To calculate the variance and standard deviation of the given data set: 10, 12, 8, 14, 16, we will follow these steps:

### Step 1: Calculate the Mean (x̄)
The mean (average) is calculated using the formula:
\[ x̄ = \frac{\sum x}{n} \]
where \( \sum x \) is the sum of all data points and \( n \) is the number of data points.
