4.3 Using Excel’s Functions to Obtain the Measures
Sample 1
- Next to the column containing Sample 1 (between Sample 1 and Sample 2), click on an empty cell of the worksheet and type Mean.
- Click on the cell right next to it and type
=AVERAGE(A2:A101)
.
Note: You can also use the Excel function Average by clicking: Formulas > Insert Function
.
- Below the cell Mean, type the word Median.
- Click on the cell right next to it and type
=MEDIAN(A2:A101)
. - Below the cell Median, type Stand. Dev.
- Click on the cell right next to it and type
=STDEV.S(A2:A101)
(sample standard deviation).
Note: The STDEV.P
calculates the standard deviation based on the entire population given as arguments and the STDEV.S
estimates the standard deviation base on a sample.
- Excel does not have a Range function, so below the standard deviation type the word Range and next to it compute the range by using the formula
Range = Max – Min
. - Below the cell Range, type Mode(s).
You will investigate the many modes in the data set and what they are. For that, you will use the function MODE.MULT()
. This function returns a vertical array of the most frequently occurring, that is, the mode(s) of the data set.
- Starting with the cell next to the word Mode(s), select a vertical range of cells (a block of any number of vertical cells).
- While the block of cells is selected, type the function
MODE.MULT(A2:A101)
into the Formula bar. - Press the keys
Control
+Shift
+Enter
(For MAC, use the keysCommand
+Shift
+Enter
).
Note: Be careful! If you only press Enter or use the function MODE, Excel will only display one value for the mode even if there are multiple modes.
Note: If there is no mode, #N/A will appear as a result. If there is only one mode, MODE.MULT returns the same value repeatedly.
