- From Minitab Solution Center Data Prep, select .
- Choose .
- In Continuous variables, select days open.
- In Gallery, use the gallery scroll bar to visualize the data in different graph types. For this example, we create a histogram and a pie chart.
- Select Create.
This histogram shows the three distinct distributions by channel.
This pie chart shows the percentages of the three channel types.
Use One-Way ANOVA to determine differences
From the graphical visualizations, there appears to be a difference in the amount of time it takes to close a claim that depends on the channel. To statistically test this difference, the insurance company performs a one-way ANOVA test.
- Choose .
- From the dropdown, select Response data are in one column for all factor levels.
- In Response, enter days open.
- In Factor, enter channel.
- Click OK.

AI technology may make mistakes, it is the user’s responsibility to ensure the output is accurate, appropriate, and meets your organization’s standards, expectations, and requirements.
What's next
Because there is a significant difference between channels, the team wants to explore how to open more claims online versus through a broker or over the phone. Go to Example of brainstorming ideas.
