WebFor Welch's ANOVA, Minitab uses the degrees of freedom for the denominator to calculate the probability of obtaining an F value that is at least as extreme as the observed F value. Interpretation. Minitab uses the F-value to calculate the p-value. Typically, you should assess the p-value because it is easier to interpret. WebOct 20, 2016 · Also, regarding the t-table I linked, is this table only for one-tailed t-tests? Directly it's for one-tailed but you can use it with two-tailed tests. I'll explain the one-tailed use and then discuss how to do it for two-tailed tests. There is no value close to 0.43 in the row of df = 26 on the t-table, so what do I do?
