Exam 17: Beyond the Basics in Basic Data Analysis

The total sum of squares is equal to the ____.

Which procedure tests that statistical significance of all possible group differences between means even when no hypothesis about such differences exists?

Which tool involves an automatic interaction routine combining cross-classification and regression analysis?

The denominator of an F-statistic has ____________________ degrees of freedom.

The degrees of freedom associated with the between-groups sum of squares is equal to____________________.

In ____________________ -subjects experimental design,experimental subjects are exposed to multiple treatment combinations in the same experiment.

The formula given below yields the ____.

The mean square within groups is equal to ____.

The SST is computed by squaring the deviation of each observed value from the grand mean and summing these values.

Which tool graphically depicts what-if analyses illustrating the chances of some event occurring?

Within-subjects designs involve repeated measures because with each treatment,a different subject is measured.

In the F-statistic,SST = SSE + SSB.

How are sequential chi-square analyses useful when analyzing big data?

An RBD allows the analyst to control statistically for the impact of a blocking variable.

The formula given below yields the ____.

If MSB=803.7 and MSE=520.4,the F-ratio is equal to ____.

In a two-factor experimental design model,Yᵢⱼk = µ + βᵢ + αⱼ + Iᵢⱼ + εᵢⱼₖ,what does µ represent?

In a two-factor experimental design model,Yᵢⱼk = µ + βᵢ + αⱼ + Iᵢⱼ + εᵢⱼₖ,Iᵢⱼ represents the interaction effect of factors A and B.

The total sum of squares minus the within-group sum of squares is equal to the between-group sum of squares.
