Compute the average of these eight scores: 124, 856, 331, 227, 963, 338, 259, 662.

Introduction / Context:Average equals total divided by count. With eight data points, careful addition is essential.Given Data / Assumptions:

• Scores: 124, 856, 331, 227, 963, 338, 259, 662

Concept / Approach:Sum all values first, then divide by 8.Step-by-Step Solution:

Verification / Alternative check:Group sums for confirmation, for example (124 + 856) = 980 and (331 + 227) = 558 etc., leading to 3760 total.Why Other Options Are Wrong:

• 350, 570, 660: Do not equal the exact computed average.

Common Pitfalls:Misadding or skipping a term which distorts the final mean.Final Answer:
