The formula used to calculate Σ(X + 1)² is

Σ(X + 1)² = Σ(X² + 2X + 1) = ΣX² + 2ΣX + N

where N is the number of scores.

Using this formula, we can find Σ(X + 1)² for the given scores:

Σ(X + 1)² = Σ(1 + 1)² + Σ(3 + 1)² + Σ(0 + 1)² + Σ(1 + 1)²
Σ(X + 1)² = 4² + 4² + 1² + 4²
Σ(X + 1)² = 33

Therefore, the statement is false.

For the Following Scores,Σ(X + 1)² = 81.Scores: 1,3,0,1
