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.


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 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.
