F Test Critical Value Chart. Note that the f inv rt function in excel will throw an error if any of the following occur. Significance level to a z value t value chi square value or f value using the inverse cumulative probability density function inverse cumulative pdf of the respective distribution.
Note that this also matches the number we would find in the f distribution table with α 0 05 df1 numerator degrees of freedom 4 and df2 denominator degrees of freedom 6. For example to determine the 05 critical value for an f distribution with 10 and 12 degrees of freedom look in the 10 column numerator and 12 row denominator of the f table for alpha 05. For the f test critical value distribution table for alpha 0 05 below the rows represent denominator degrees of freedom and the columns represent numerator degrees of freedom.
You can use the interactive f distribution applet to obtain more accurate measures.
F 05 10 12 2 7534. Find critical value of f for f test. For example f 2 19 0 95 3 522. The right tail area is given in the name of the table.
