Source Between treatments Within treatments Sum of Squares (Ss) df Mean Square (MS) 2 310,050.00 2,650.00 In some ANOVA summary tables you will see, the labels in the first (source) column are Treatment, Error, and Total Which of the following reasons best explains why the within-treatments sum of squares is sometimes referred to as the "error sum of squares"? O Differences among members of the sample who received the same treatment occur when the researcher O Differences among members of the sample who received the same treatment occur because some treatments O The within-treatments sum of squares measures treatment effects as well as random, unsystematic makes an error, and thus these differences are sometimes referred to as "error." are more effective than others, so it would be an error to receive the less superior treatments differences within each of the samples assigned to each of the treatments. These differences represent all of the variations that could occur in a study; therefore, they are sometimes referred to as "error." O The within-treatments sum of squares measures random, unsystematic differences within each of the samples assigned to each of the treatments. These differences are not due to treatment effects because everyone within each sample received the same treatment; therefore, the differences are sometimes referred to as error In ANOVA, the F test statistic is the variance. The value of the F test statistic is of the between-treatments variance and the within-treatments When the null hypothesis is true, the F test statistic is statistic is most likely When the null hypothesis is false, the F test . In general, you should reject the null hypothesis for
