If x is 4 and the distribution is 2, 3, 4, 5, 6, the sum of squared deviations from the x will be______________?
Correct answer: B. 10
- A. 8
- B. 10
- C. 6
- D. 12
Explanation
The squared deviations from 4 are (2−4)², (3−4)², (4−4)², (5−4)² and (6−4)², which sum to 4+1+0+1+4 = 10. Thus the required total is 10.
