Use the SUBTOTAL function to count the number of values in an Excel table or range of cells. There are four types of frequency distributions: Ungrouped frequency distributions: The number of observations of each value of a variable. For example, 40th percentile (P40) refers to the approximately 40th data of the 100 data.If the data set is not exactly 100, say 200, we find the location of observation at 40% of total data.
