Step 1
- Histogram :
A histogram is the most commonly used graph to show frequency distributions. It looks very much like a bar chart, but there are important differences between them. This helpful data collection and analysis tool is considered one of the seven basic quality tools.
- Peaks and spread :
Identify the peaks, which are the tallest clusters of bars. The peaks represent the most common values. Assess the spread of your sample to understand how much your data varies.
- When to use :
Use a histogram when:
- The data are numerical
- You want to see the shape of the data’s distribution, especially when determining whether the output of a process is distributed approximately normally
- Seeing whether a process change has occurred from one time period to another
- Determining whether the outputs of two or more processes are different
- You wish to communicate the distribution of data quickly and easily to others
