F = 0.0047F-Test calculator calculates the F-Test statistic (Fisher Value) for the given two sets of data $X$ and $Y$. It's an online statistics and probability tool requires two sets of real numbers or valuables. It is necessary to follow the next steps: Enter two samples (observed...
If the variances are not equal, the F-statistic will differ from one. The degrees of freedom are the sample sizes minus one. F-Test Assumptions Normality - Each population is normally distributed. The F-test for equality of variances is highly sensitive to deviations from normality. ...
Sample Mean, x: Standard deviation, σ: Sample Size, n: Test Statistic for One Population Mean: The Test Statistic for One Population Mean Calculator is a calculator that is used when the variable is numerical and only one population or group is being studied. ...
the sample mean of 011242432014061112and 017551892 is 0.02076634.3 Having obtained the -test statistic using a hand-calculator, we need tables of the F-distribution in order to obtain the corresponding -. The F- distribution is very similar in shape to the Chi-square distribution.4 However, ...
