COUNTIF
COUNTIF is “one of Excel’s statistical functions, to count the number of cells that meet a criterion” - Microsoft Support Office 2017. In layman’s terms, it means “COUNT the NUMBER of cells, IF it contains XYZ (text, number, etc.)”. The key word here is criterion, referring to only one criteria.
Excel Formula: =COUNTIF(range,criteria)

Examples
I have some crime data for January. It contains the following:
Council Area - which area the offence occurred
Offence
Offence Category
Date of Offence
Gender
I want to know the NUMBER (count) of offences that were committed by EACH GENDER (if / condition).
Based on the above photo, if I were to fill in the cell references into my Formula Made Easy table, it will look like:

Putting the above references into the Excel formula, it will be:
=COUNTIF(E:E, “Male”)
=COUNTIF(E:E, “Female”)

Based on the above photo, if I were to fill in the cell references into my Formula Made Easy table, it will look like:

Putting the above references into the Excel formula, it will be:
