A conditional test formula compares two numbers, functions, formulas, labels, or logical values. You can use conditional tests to flag values that fall outside a given threshold, for example. You can use simple mathematical and logical operators to construct logical formulas, or you can use an assortment of built-in functions. For information about using conditional test functions, see "Understanding Logical Functions".
Each of the following formulas performs a rudimentary conditional test:
=A1>A2 =5−3<5*2 =AVERAGE(B1:B6)=SUM(6,7,8) =C2="Female" =COUNT(A1:A10)=COUNT(B1:B10) =LEN(A1)=10
Every conditional test must include at least one logical operator, which defines the relationship between elements of the conditional test. ...
