VARPA

The VARPA function calculates the variance for data that represents an entire population. Variance provides a general idea of the spread of data. The difference between the VARPA function and the VARP function is in how these functions handle logical values and numbers as text. The VARP function will ignore text values and logicals when the appear in references, while the VARPA function will evaluate text as zero, TRUE as 1, and FALSE as zero. Note that both VARP and VARPA will evaluate logical values, and numbers as text when they are hardcoded directly as arguments. In the example shown, the formula in F5 is: Note that the VARP function ignores the "NA" text in C8, while VARPA includes this in the variance estimate as zero.
