AVERAGE (Mean) Function Sales Call Example

Standard Deviation Function Sales Call Example

Proportion • • =COUNTIF DIVIDE COUNTIF BY COUNT =D 3/D 2

Frequency Distributions • There alternative ways of constructing frequency distributions • COUNTIF function • HISTOGRAM function

=COUNTIF(A 6: A 134, 1) =D 4/D 9*100
