## Chi-Square Test for Variance

Test Variance The hypothetical variance to be tested. The null hypothesis to be tested (i.e. sample variance = Test Variance). Options: Variance <> $\boldsymbol{\sigma}0$ The sample variance differs from the hypothetical variance. Variance > $\boldsymbol{\sigma}0$ The sample variance is larger than the hypothetical variance (upper-tailed test). Variance < $\boldsymbol{\sigma}0$ The sample variance is less than the hypothetical variance (lower-tailed test). The significance level of the test. Compute confidence intervals for sample variance. Specify space-separated confidence levels (%). This option is only available when Confidence Interval(s) is selected.

## Plots

Histogram Plot a histogram of sample data. Plot a box chart of sample data. Put the plots of same type in one graph. Note that for histograms, the layers will be arranged vertically; for box charts, layers will be arranged horizontally.

## Output
