SS, variance, and standard deviation using computational formula
1. Compute the SS, variance, and standard deviation for the following population of N = 4. Scores: 3, 1, 1, and 1 (Note: the definitional formula works well with these scores). Hint: use the computational formula to find out SS, variance, and standard deviation.
2. Work out the SS, variance, and standard deviation for the following population of N = 7.Scores: 8, 1, 4, 3, 5, 3, and 4. (Note: the definitional formula works well with these scores. Hint: utilize the definitional formula to find out SS, variance, and standard deviation.
