A researcher conducts an Analysis of Variance (ANOVA) test looking at the effect of different treatment program options (therapy, education and reentry services) and finds that drug use levels vary significantly among between the participants in each of these three groups. For example, the therapy group had lowest amount of drug use (mean=2.0), the education group had the highest (mean=7.0) and the reentry services group was in the middle (mean=6.0). The researcher follows the steps to conduct an ANOVA appropropriately....

One Way ANOVA (Analysis of Variance) A manufacturer of steel wants to test the effect of the method of manufacture on the tensile strength of a particular type of steel. Four different methods have been tested and the data shown in Table 1. (Use Minitab) Develop the ANOVA table and test the hypothesis that methods affect the strength of the cement. Use a = 0.05 Use the Tukey’s method with a =0.05 to make comparisons between pairs of means. Construct...
