Tendency of a Data Set
You can use three popular measures when trying to find the middle scores in
a range:
Mean
Mean The mean of a data set is the mathematical average. It is cal-
culated by adding all the values in the range and dividing by the num-
ber of values in the set. To calculate a mean in Excel, use the
AVERAGE function.
Median
Median The median of a data set is the value in the middle when the
set is arranged from high to low. In the data set, half the values are
higher than the median and half the numbers are lower than the median.
To calculate a median in Excel, use the MEDIAN function. When there
is an even number of items, the median is the average of the two middle
numbers.
Caution
When averaging cells, keep in mind the difference between empty cells
and those that contain the value 0. This can be particularly troub-
ling if you have cleared the Show a Zero in Cells That Have a Zero
Value check box. You find this setting by selecting File, Options, Ad-
vanced, Display Options for This Worksheet.
Mode
Mode The mode of a data set is the value that happens most often.
To calculate a mode in Excel 2013, use the MODE.SNGL and
MODE.MULT functions.
Syntax
=AVERAGE(number1,number2,...)
The AVERAGE function returns the average (that is, arithmetic mean) of the
arguments. The arguments number1, number2, ... are one to 255 numeric argu-
ments for which you want the average. The arguments must be either numbers
or names, arrays, or references that contain numbers. If an array or a ref-
erence argument contains text, logical values, or empty cells, those values
are ignored; however, cells containing the value 0 are included.
