WebLet's work our way through it entry by entry to see if we can make it all clear. Let's start with the degrees of freedom (DF) column: If there are n total data points collected, then there are n−1 total degrees of freedom. If there are m groups being compared, then there are m−1 degrees of freedom associated with the factor of interest. WebLooking for the degrees of freedom (df) we see that MINITAB got 62, whereas we got 63. By the time we are dealing with 60-odd degrees of freedom the critical values do not ... in our manual calculations as we can only input so many decimal places, whereas MINITAB can use dozens.
