The standard deviation of an arithmetic progression can be calculated using a specific formula. The formula involves taking the square root of the variance of the progression, which is calculated by subtracting the mean from each term, squaring the results, summing them, and dividing by one less than the number of terms. This allows one to determine the spread or variation from the average of the values in the arithmetic progression.
