What is the value of SS (sum of squared deviations) for the following sample? Sample: 2, 3, 4, 7
A)14/3 = 2.67
B)14
C)72
D)78

Question

Quizplus · Accepted Answer

The sum of squared deviations (SS) is calculated by finding the mean of the sample, subtracting each value from the mean, squaring the result, and then summing these squared differences. For the sample 2, 3, 4, 7, the mean is 4. The squared deviations are (2-4)² + (3-4)² + (4-4)² + (7-4)² = 4 + 1 + 0 + 9 = 14.
