Chi-Square Test for Variance

Test Variance	The hypothetical variance to be tested.
Null Hypothesis	The null hypothesis to be tested (i.e. sample variance = Test Variance).
Alternate Hypothesis	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).
Significance Level	The significance level of the test.
Confidence Interval(s)	Compute confidence intervals for sample variance.
Confidence Level(s) in %	Specify space-separated confidence levels (%). This option is only available when Confidence Interval(s) is selected.

Plots

Histogram	Plot a histogram of sample data.
Box Chart	Plot a box chart of sample data.
Arrange Plots of Same Type in One Graph	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

Output Plot Data	Specify a worksheet for output of plotted data (Origin generates tabular data when plots are created).
Output Results	Specify the worksheet for output of test results.
