Project Details (PC Users)

Float_Left Professor Charles is using Microsoft Excel for statistical analyses in her class. This page is a resource for PC users to help you to understand how to use a variety of Excel's basic statistical functionality.

Hardware/Software

  • Microsoft Excel for PC

What We Will Cover

  • Selecting cells within an Excel file
  • Using built-in functions for central tendency and variability
  • Using the Analysis ToolPak Add-in

Cell Selection

  • Enter: go to row below the current row
  • Shift+Enter: go to row above the current row
  • Tab: go to the column right of the current column
  • Shift+Tab: go to the column left of the current column
  • Control+Click: hold down control while clicking new cells to select as many individual cells as desired.
  • Shift+Click: selects all cells between the currently selected cell to the desired cell being clicked. Works across rows and columns.

Float

Central Tendency

Mean

1. Select the cell where you would like the mean value to be output.
2. Navigate to the Formulas tab in the Menu bar ==> More Functions ==> Statistical ==> AVERAGE.

3. The Function Arguments window below will appear, as seen below. Excel will attempt to guess your data set, but this can be manually selected with the next step.

4. Now, click on the first cell of your data set (behind the Function Arguments window); then, while holding down the shift key, click on the final cell of your data set.

5. Hit enter, and the mean of your data set will be output into the cell that you picked.

Median

1. Select the cell where you would like the median value to be output.
2. Navigate to the Formulas tab in the Menu bar ==> More Functions ==> Statistical ==> MEDIAN.

3. The Function Arguments window will appear, as seen below. Excel will attempt to guess your data set, but this can be manually selected with the next step.

4. Now, click behind this window on the first cell of your data; then, while holding down the shift key, click on the final cell of your data.

5. Hit enter, and the median of your data set will be output into the cell that you picked.

Mode

1. Select the cell(s) where you would like the mode value(s) to be output. 

Note: It is important to select an excess of output cells, as data sets may have more than one mode value.
Too few output cells will result in receiving only a portion of the mode values for a data set.

2. Navigate to the Formulas tab in the Menu bar ==> More Functions ==> Statistical ==> MODE.MULT.

ModeStep1.png

3. The Function Arguments window will appear, as seen below. Excel will attempt to guess your data set, but this can be manually selected with the next step.

ModeStep2.png

4. Click behind the Function Arguments window on the first cell of your data; then, while holding down the shift key, click on the final cell of your data.

ModeStep3.png

5. CAUTION: after selecting the cells of your data set, do NOT hit enter and do NOT click OK; instead hit ctrl+fn+enter. This will output
the mode(s) of your data set into the cell(s) that you picked. Cells that do not receive a mode value will receive an "#N/A".

Variability

Variance

1. Select the output cell for the desired type of variance (either sample variance or population variance).

2. Go to the Formulas tab.

3. For sample variance, navigate to the Formulas tab in the Menu bar ==> More Functions ==> Statistical ==> VAR.S.

4. For population variance, navigate to the Formulas tab in the Menu bar ==> More Functions ==> Statistical ==> VAR.P.

VarStep1.png

5. Now, click on the first cell of your data set (behind the Function Arguments window); then, while holding down the shift key, click on the final cell of your data set. Then, hit enter or select OK.

Standard Deviation

1. Select the output cell for the desired type of standard deviation (either sample or population standard deviation).

2. Go to the Formulas tab.

3. For sample standard deviation, navigate to the Formulas tab in the Menu bar ==> More Functions ==> Statistical ==> STDEV.S.

4. For population standard deviation, navigate to the Formulas tab in the Menu bar ==> More Functions ==> Statistical ==> STDEV.P.

StDev1.png

5. Now, click on the first cell of your data set (behind the Function Arguments window); then, while holding down the shift key, click on the final cell of your data set. Then, hit enter or select OK.
