An ANOVA table has a Materials DF = 2 and a Machines DF = 2.
Calculate the critical values assuming 95% confidence as:
F 0.05,2,10 = 4.10 for both sources
Can someone please explain where the “10” comes from in this calculation?
Also – can someone please explain how the 4.10 number is generated from this equation? I tried .05*2*10 but this equals 1….
Homework is best accomplished as an individual effort. But this time only…….First understand the F statistic….Source divided Error. Or between divided by within. F is a ratio whose value is determined by the degrees of freedom for the numerator and denominator. That is the 2 and 10. Of course the .05 value is the alpha or 1 minus .95 confidence. From there assume a one tailed test and you get 4.10 in the F tables or in Minitab. You didn’t show the complete table so we can’t see the 10 that is probably associated with the Error.
