Start up Excel. Notice that each row has a number, and each column has a letter. Click in A1 (column A, row 1), and type in a title for your data

Now below that header, enter your data, one value in each line.

Near your data, enter the names: mean, std dev, min, Q1, median, Q3, max

Now click in the cell to the right of the name mean (D2 in my example). Type in: =average(A2:A20) And press ENTER This will calculate the average (mean) of the data starting in A2 and going to A20

In the cell next to “std dev”, Type in: =stdev(A2:A20) In the cell next to “min”, Type in: =min(A2:A20) In the cell next to “Q1”, Type in: =quartile(A2:A20,1) In the cell next to “median”, Type in: =median(A2:A20) In the cell next to “Q3”, Type in: =quartile(A2:A20,3) In the cell next to “max”, Type in: =max(A2:A20)

Now lets create a frequency distribution. Click on cell C10, and type in a description for each of your classes.

Starting at D10, type a list of your upper class limits.

Now, use the mouse to highlight (click and drag) cells E10 through E14 Type in: =frequency(A2:A20,D10:D14) Then hold down Ctrl and Shift while you press Enter. Note that A2:A20 are the cells holding your data, and D10:D14 are the cells containing upper class limits

Highlight cells C10 through C14, then hold down Ctrl while clicking and dragging to also highlight cells E10:E14.

Click on the chart tool in the toolbar

Click Next twice. Enter a title and axes labels for your chart. If you want, you can use the tabs across the top to turn off the legend.

Click Finish to complete the graph

To make it look more like a histogram, right-click on the bars, and select “Format Data Series”. Choose the Options tab, and set the gap width to 0. This graph can now to cut-and-pasted into Word or PowerPoint.
