The standard deviation, on the other hand, measures the amount of variation or dispersion in a dataset. It's calculated by finding the square root of the variance, which is the average of the squared differences from the mean. For the same dataset, the standard deviation would be √((2-6)^2 + (4-6)^2 + (6-6)^2 + (8-6)^2 + (10-6)^2) / 5 = 2.83.
Calculating mean and standard deviation is essential for anyone working with data, including:
