Use the Test Std Dev option to perform a one-sample test for the standard deviation. Use the Test Std Dev option repeatedly to test different values. Each time you test the standard deviation, a new Test Standard Deviation report appears.
Test Statistic
Provides the value of the Chi-square test statistic. See Standard Deviation Test.
Min PValue
The probability of obtaining a more extreme Chi-square value when the population standard deviation does not differ from the hypothesized value. See Standard Deviation Test.
Prob>ChiSq
The probability of obtaining a Chi-square value greater than the computed sample Chi-square when the population standard deviation is not different from the hypothesized value. This is the p-value for observed significance of a one-tailed t test.
Prob<ChiSq
The probability of obtaining a Chi-square value less than the computed sample Chi-square when the population standard deviation is not different from the hypothesized value. This is the p-value for observed significance of a one-tailed t test.
