What is the value of Σ(X − 2)^2 for the scores 2, 3, 5?

Explanation:
You’re summing squared differences from a fixed value, here 2, across the scores 2, 3, and 5. Compute each squared deviation: - (2 − 2)² = 0 - (3 − 2)² = 1 - (5 − 2)² = 9 Add them: 0 + 1 + 9 = 10. So the value is 10, which matches the option that lists 10.

You’re summing squared differences from a fixed value, here 2, across the scores 2, 3, and 5.

Compute each squared deviation:

  • (2 − 2)² = 0

  • (3 − 2)² = 1

  • (5 − 2)² = 9

Add them: 0 + 1 + 9 = 10.

So the value is 10, which matches the option that lists 10.
