In a  One-Way Analysis of Variance Table which of the following statements is necessarily true?Group of answer choicesThe "Sum of Squares for Groups" measures the variation among individual observations within the group.A "Large" F-value means that most of the observed variation in the response variable is due to sampling variability.The F-test compares the variation between the groups with the background variation within each group.Comparing the means for two independent populations (with unknown standard deviations) using an ANOVA  (F-test) is, necessarily, equivalent to using an independent samples t-test.An F-test is useless because it doesn't tell us which treatment produces "optimal" results

A researcher has collected the following sample data.   351232The variance isGroup of answer choices

In a study involving 4 treatment groups, and numerous trials done in each, the variances gave the totals of : SST=25.8 and SSE=145.7 for dfT=3 and dfE=31.Consider the mean squares and calculate the F-statistic for this data?

How is the F-statistic in an ANOVA test calculated?a.)The variance between the samples minus the variance within the samplesb.)The variance between the samples plus the variance within the samplesc.)The variance between the samples divided by the variance within the samplesd.)The variance between the samples multiplied by the variance within the samples
