Step1: Recall the formula for variance
Variance $s^{2}=\frac{\sum_{i = 1}^{n}(x_{i}-\bar{x})^{2}}{n}$, where $\sum_{i = 1}^{n}(x_{i}-\bar{x})^{2}$ is the sum of the squared - differences from the mean and $n$ is the number of data points. Cell D14 is the sum of the values in column D, which is used to calculate the variance.
Step2: Identify the sum value
The sum of the values in column D (the squared differences from the mean) is 70.
