The steps are as follows: Calculate the mean (average) of the scores. Subtract the mean from each score, square the result. Calculate the mean of those squared differences. Take the square root of that mean to get the standard deviation. Step 1: The mean is indeed 5.5. Step 2: Subtract the mean from each
