Excel provides useful functions for finding the mean, median, and mode of a data set. In general, the functions look at a set of values and then make the expected calculation. For example, the mean functions, which calculate averages, take the sum of the values in the set and divide it by the number of values.AVERAGEThe AVERAGE function ignores cells that contain text, that are empty, or that contain logical values. To use the AVERAGE function, simply enter the data set range as the single argument using the following syntax:=AVERAGE (data set range)For example, if you wanted to find the average birth rate per 1,000 people in the United States in 1996 using the data in Figure 4-11, you would use the following formula:=AVERAGE (C2:C52)The function returns the value 14.27.AVERAGEAThe AVERAGEA function includes cells containing text or logical values in the calculation. Excel includes cells containing the word TRUE as the value 1 in the calculation; it includes cells containing the word FALSE or any other text as the value 0.To use the AVERAGEA function, simply enter the data set range as the single argument in the function using the following syntax:=AVERAGEA (data set range)Median (MEDIAN)The median is the middle value in a set of values. Half of the data in the set fall above this value and half fall below, so the median estimates the 50% quantile.The MEDIAN function uses the following syntax:=MEDIAN (data set range)If the data set contains an even number of values, Excel averages the two middle values.Mode (MODE)The mode is the most-frequently occurring value in a set of values.When Excel calculates the mode, it ignores empty cells and cells containing text or logical values. The MODE function uses the following syntax:=MODE (data set range)Geometric Mean (GEOMEAN)If you have a set of n numbers, the geometric mean of the set is the nth root of the product of the numbers.To find the geometric mean, enter the data set range as the sole parameter of the GEOMEAN function, which uses the following syntax:=GEOMEAN (data set range) Article Tags: Includes Cells Containing, Logical Values, Following Syntax, Includes Cells, Cells Containing, Geometric Mean
