6. Calculating standard deviation and variance using the computational formula Consider a data set containing the following values: The mean of the given values is 71 . The squares of the scores have been calculated as follows: If the preceding scores are sample data, the sum of squares (SS) is to the sum of squared deviations.) (Hint: Remember that the phrase "sum of squares" or SS refers If the preceding scores are population data, the sS is If the preceding scores are sample data, the sample standard deviation is and the sample variance is If the preceding scores are population data, the population standard deviation is and the population vanance is
