Question

Conduct a one-way between-subjects ANOVA using the data above. Use an α level of 0.05. Based on scenario a, what is SST (Sum of Squares Total)?

a. The total variability in the data
b. Variability within groups
c. Variability between groups
d. The mean of the dependent variable

Answer 1

In a one-way between-subjects ANOVA, SST represents the total variability in the data.

Step-by-step explanation:

In a one-way between-subjects ANOVA, the SST (Sum of Squares Total) represents the total variability in the data. It is the sum of the squares of the differences between each data point and the overall mean.

To calculate SST, you need to find the sum of squares for each group (SSwithin) and the sum of squares between groups (SSbetween). Then, add these two values together to get SST.

Hence, the answer is a. The total variability in the data.
