The probability of a score between 0 and 1 is the same as the probability of a score between 0 and 1: both are .34. To calculate the standard deviation, statisticians first calculate the mean value of all the data points. The mean is equal to the sum of all the values in the data set divided by the total number of data points. Next, the deviation of each data point from the average is calculated by subtracting its value from the mean value. PowerPoint Presentation Last modified by: The Standard Deviation = 0.67. Chapter 4.
