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
