Bartlett's Test

For Equal Variance

 

Other Equal Variance Tests:

Levene's Test

Quartiles Report

Box Plot

Description:

 

Bartlett's test is a test for equal variance among the distribution from each individual well. It is assumed for Bartlett's test that data follow a normal distribution. Box Plots and Levene's test are additional methods to test for equal variance among the distribution from each individual well.

 

 

Use:

 

To test for equal variance between the wells.

 

 

Remarks:

 

Bartlett's test is presented in the 1989 guidance. The 1992 guidance recommends Levene's test and Box Plots as methods to test for equal variance that are less sensitive to non-normality in the data.
