Pooled standard deviation from anova table
WebThis Excel formula also gives the answer: =TDIST (t, DF, 2). The first value is the t ratio computed in step 4, the second value is the number of degrees of freedom from the ANOVA (number of values minus number of groups) and the third value is 2 because you want a two-tailed P value. Remember this P value is NOT corrected for multiple comparisons. WebSD 2 = 0.339. The easiest way to calculate d values is to firstly calculate the pooled standard deviation. Thus, taking these values and entering them into the equation are shown …
