In MS Excel, the COUNTIF function
Answer: C
Correct answer: counts the cells in a range that meet a given condition
COUNTIF counts the cells in a range that satisfy one condition: =COUNTIF(A1:A100,"Delhi") counts how many entries are Delhi, and =COUNTIF(B1:B100,">50") counts the values above fifty. The condition is given as text, which is why comparison operators must be inside quotation marks. Wildcards are allowed: ? stands for one character and * for any number, so "D*" matches every entry beginning with D. Its relatives complete the family. SUMIF adds rather than counts. AVERAGEIF averages. The plural forms - COUNTIFS, SUMIFS, AVERAGEIFS - take several conditions at once, and note that SUMIFS reverses the argument order, putting the sum range first. The plain COUNT counts numeric entries only, COUNTA counts any non-empty cell, and COUNTBLANK counts the empty ones.
