One-Sample Standard Deviation Test
The One-Sample Variance test is used to test if the sample was drawn from a population with a variance equal to some hypothesized value.
The following hypotheses may be tested:
Where is the true population variance from which the sample was drawn, and is the hypothesized population value.
- The sample has been randomly drawn from the population (Critical)
- The population from which the sample has been drawn is normally distributed (Critical)
- The measurements are at least Interval Level (Critical)
Where has n -1 df
