Options A and C correctly use AVERAGEIF(range, criteria, average_range); A omits average_range (defaults to criteria_range) and C specifies it explicitly where both range and average_range are the same.
Option B uses the wrong criteria <100.
Option D averages all values without any condition.
Option C correctly uses AVERAGEIFS(average_range, criteria_range1, criteria1, criteria_range2, criteria2).
Option C adds two averages separately, which is incorrect.
Option C swaps average_range and criteria_range, causing wrong output.
Option C uses AVERAGEIF with mismatched ranges.
AVERAGEIFS supports multiple conditions, so option A is correct.
AVERAGEIF supports only one condition.
SUMIF and COUNTIF calculate sums and counts, not averages.
=AVERAGEIF(A2:A10, ">50", B2:B10) but the result seems wrong. Column B contains numbers and some text like "N/A". What is the likely cause?Text values in the average_range are ignored in average calculations, which can skew results if many are present.
Option D is false; ">50" is valid criteria.
Option D ignores the condition.
Option D is incorrect; ranges can differ.
Option A correctly uses "<>Complete" to exclude "Complete" status.
Option A includes only "Complete" status, wrong condition.
Option A subtracts averages incorrectly.
Option A uses wrong ranges and criteria.
