Data

Answer

200

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 = -150 ÷ 5 = -30

Step 2 — Find each squared deviation from the mean

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

(-10 − -30)² = 400

(-20 − -30)² = 100

(-30 − -30)² = 0

(-40 − -30)² = 100

(-50 − -30)² = 400

Step 3 — Average the squared deviations

Divide the sum of squared deviations by the count:

Variance = 1000 ÷ 5 = 200

Variance = 200
