F-statistic (the critical value for F-Test) is determined by the formula $$F=\frac{s_X^2}{s_Y^2}$$If the variances are equal, then the ratio of the variances is $1$. The larger sample variance should be in the
P value formula X is the test statistic value, and you know the distribution of X.For example X may be Z, T etc. Left tailed: P-value = p(x≤X) Right tailed: P-value = 1 - p(x≤X) Two tailed: P-value = 2 * Min( p(x≤X), 1 - p(x≤X) ) ...
Hand-calculation is a tedious and error- prone process, especially with large data sets. This section gives formulae for calculating the -test statistic and introduces tables of the -distribution for those situations in which computers with statistical software are not easily available. We take ...

Equations can be solved using a simple order of operations, also known as PEMDAS: We first sort out Parentheses, followed by Exponents, Multiplication, and Division (left to right), then Addition and Subtraction (left to right). To solve a mul...

Use the formula:=F.DIST ( B3, B4, B5, TRUE)The f distribution probability comes out 0.889 or 88.9% for the value for at least 5. The F-distribution is a method of obtaining the probabilities of specific sets of events occurring. The F-statistic is often used to assess the significant...
