... A fractile ranking means that a given number of measurements lie below the given measurement and a given number above. Suppose your child comes home to tell you that she’s in the 90th percentile of her class on a particular test. This means that 90% of the children have lower scores or the same scor ...

The analysis of variance (ANOVA) procedure enables us to perform a test of the research hypothesis, Ha, of whether there are any differences in the means of several populations, provided that certain assumptions hold. Using data obtained by taking simple random samples from each population, the test ...

These sort of questions can be answered by using Scheffé’s Test. This procedure allows us to test as many contrasts as we desire and to decide upon these cont ...

... 1.328 and 1.729, corresponding to a p-value between 0.05 and 0.10. Since this is a two-sided test, we multiply the p-values by 2 to get a p-value between 0.10 and 0.20. We could have also found P(T ≠ -1.479) using the calculator: P(T < -1.479) = tcdf(-1E99, -1.479, 19) = 0.0778. For our two-sided te ...
