To calculate the standard deviation, you need tocalculate the variance first as the standard deviationis the square root of the variance. The standard deviation can be of 2 kinds. They are population standard deviation and sample standard deviation. The formula for calculating the standard deviation...
of chips is 214, and since these chips are in a total of 11 bags, the mean value is 214 / 11, or about 19.45. Although it looked a little different, this is the same type of averaging used to calculate batting averages in the previous article. Check out this week’s Math Dude ...
