Which of these is a conditional function and is properly defined?COUNT() counts the number of cells that are not empty in a range while COUNTA() counts the number of cells in an array that have a number value in them.IF() function alway outputs falseCOUNTIF() is used to count the number of cells that meet a criterionAVERAGE() and AVERAGEIF() perform exactly the same way

The statement "COUNTIF() is used to count the number of cells that meet a criterion" is a conditional function and is properly defined.

Here's why:

1. COUNT(): This function counts the number of cells that contain numbers in a range. It does not count non-empty cells, so the definition given is incorrect.

2. COUNTA(): This function counts the number of cells that are not empty in a range, not just those that contain numbers. So, the definition given is incorrect.

3. IF(): This function does not always output false. It checks whether a condition is met, and returns one value if true and another value if false. So, the definition given is incorrect.

4. COUNTIF(): This function counts the number of cells within a range that meet the given condition. This is correctly defined in the question.

5. AVERAGE() and AVERAGEIF(): These two functions do not perform exactly the same way. AVERAGE() returns the average of its arguments, while AVERAGEIF() returns the average (arithmetic mean) of all the cells in a range that meet a given criteria. So, the definition given is incorrect.
