Data

Answer

424

To find the population variance of 5 values, follow the step-by-step solution below.

Step 1 — Find the mean

Add all values and divide by the count:

Mean = 130 ÷ 5 = 26

Step 2 — Find each squared deviation from the mean

For each value, subtract the mean and square the result:

(-10 − 26)² = 1296

(20 − 26)² = 36

(30 − 26)² = 16

(40 − 26)² = 196

(50 − 26)² = 576

Step 3 — Average the squared deviations

Divide the sum of squared deviations by the count:

Variance = 2120 ÷ 5 = 424

Variance = 424
