Question

A video game developer is testing a new game on three different groups. Each group represents a different target market for the game. The developer collects scores from a random sample from each group. The results are shown in the Table.

$\begin{array}{|lll|}\hline \text{Group A}& \text{Group B}& \text{Group C}\\ 101& 151& 101\\ 108& 149& 109\\ 98& 160& 198\\ 107& 112& 186\\ 111& 126& 160\\ \hline\end{array}$

What are the $S{S}_{\text{between}}$ and $M{S}_{\text{between}}$ ?

Short answer

Thus, value $S{S}_{\text{Between}}$is $5700.4$and $M{S}_{\text{Between is}}$$2850.2$.

Step-by-step solution

Given Information

Use the below-given table of three different groups of target markets for the game, to calculate $S{S}_{\text{Bctween}}$and role="math" localid="1649069820372" $M{S}_{\text{Between}}$.

$\begin{array}{|lll|}\hline \text{Group A}& \text{Group B}& \text{Group C}\\ 101& 151& 101\\ 108& 149& 109\\ 98& 160& 198\\ 107& 112& 186\\ 111& 126& 160\\ \hline\end{array}$

Explanation

To calculate $S{S}_{\text{Between}},M{S}_{\text{Between}}$use $Ti-83$calculator. For this, click on STAT $\to$press $1\to$EDIT, then put the above-given weights of different group's data into the list $L1,L2$, and $L3$. The screenshot is given below:

Now Again press the START $\to$arrow over the TESTS $\to$arrow down to ANOVA $\to$Press var then select$1$ , press var then select $2$and press var then select $3$to fill the values of $L1,L2$, and $L3$. The screenshot is given below:

Final Answer

Press ENTER. The screenshot of the obtained output of the calculated value $S{S}_{\text{Between}}$and $M{S}_{\text{Between}}$is given below
