By applying the SQRT formula to the variance (the average of the squared deviations from the mean), analysts can calculate the standard deviation of a dataset. The standard deviation provides insights into the variability and dispersion of the data points.
Calculating variance: Variance is another measure of the dispersion or spread of data points in a dataset. It quantifies how far each number in the dataset is from the mean and, therefore, provides an understanding of the variability within the dataset. The SQRT formula is used to calculate the square root of the variance, providing a more interpretable measure.

Explaining how the formula can be used to calculate standard deviation and variance in a dataset

Standard deviation: When calculating the standard deviation, the following steps are typically followed:

Calculate the mean of the dataset.
Calculate the squared difference between each data point and the mean.
Calculate the average of these squared differences, which gives us the variance.
Apply the SQRT formula to the variance to obtain the standard deviation.

Variance: To calculate the variance, we follow a similar process as in the calculation of standard deviation:

Calculate the mean of the dataset.
Calculate the squared difference between each data point and the mean.
Calculate the average of these squared differences.
The result is the variance.
