Consider a data set containing the following values: 67, 94, 82, 80, 97, 99, 78, 91. The mean of the given value is 86. The squares of the scores are calculated as follows: 4,489, 8,836, 6,724, 6,400, 9,409, 9,801, 6,084, 8,281. If the preceding scores are sample data, the sum of squares are? If the preceding scores are population data, the SS is? If preceding scores in a sample data, the simple standard deviation is? and the sample variance is?...
