WebApr 4, 2024 · I believe that your second statement of critical values is incorrect, and guess it is based on an attempt to show how to find the lower critical values from printed tables. WebA z score tells you about the fluctuating standard deviations from the mean state. The following p value formula from z score tells us how to find p value: P value for two-tailed test = p value from z score table * 2. P value for left0tailed test = p value from z score table. P value for right-tailed test = 1 – p value from z score table.

WebThe F-test statistic we use is simply the ratio of the two population variances: F = s 12 /s 22. If the null hypothesis is true, the ratio will be equal to 1; the variances are equal. But we have specific requirements for calculating the F-statistic. The larger sample variance is always s 1, the numerator; the smaller sample variance is always ...
