Interval Explorer for one sample variance

Hi All,

 

Within the DOE menu, if l select Sample Size Explorers - Confidence Intervals and Margin of Error for one Sample Variance, when i change the sample size the interval width changes, but what is the interval width telling me?

 

Thanks

Mick.

The confidence interval width represents the uncertainty in the estimate of the variance. A larger sample reduces the uncertainty and shrinks the width. A smaller sample increases the uncertainty and expands the width.
