What are some basic statistics formulas I should know?

Can you explain how to calculate the mean?
Sure! The mean is calculated by adding all the numbers in a dataset and then dividing by the count of numbers.
What about the standard deviation?
The standard deviation measures the amount of variation or dispersion in a set of values. It's calculated as the square root of the variance.
