Building a Histogram in Excel

IE 1225

R. Lindeke

After Opening Excel …

Click:

Tools … Add-Ins …

Then

Check: Analysis Toolpak Box

Enter Team/Individual Averages:

Each Team has no-replicates? Need Averages for both Diameter & Length – we will build a histogram of each!

Determine Overall Range: Excel Formulas!

=Max(C3:C32)

=Min(C3:C32)

Both Columns – diameter & Length

Excel Formula Too! Largest ‘Max’ to Smallest ‘Min’

Examine the Overall Range – Want 6 to 10 “Bins” covering this Range

Tools … Data Analysis … Histogram … ok!

In Histogram Box Click the ICON then highlight Ranges for Data (Input Range box) and Segment Limits (Bin Range box) … Put Histogram on Separate WorkSheet!

Also: Check Chart Output & Cumulative Percentage

Final Output:

Experiment with Smaller Bins sizes (more bins across Overall Range)

Using 10 Bins not 6!

Leads to a More “Normal-Like” Distribution
