question 71

Short Answer

Three tennis players, one a beginner, one intermediate and one advanced, have been randomly selected from the membership of a club in a large city. Using the same tennis ball, each player hits ten serves, one with each of three racquet models, with the three racquet models selected randomly. The speed of each serve is measured with a machine and the result recorded. Among the ANOVA models listed below, the most likely model to fit this situation is the: $\begin{array}{|l|l|}\hline \text { A. } & \text { one-way ANOVA. } \\\hline \text { B. } & \text { two-way ANOVA. } \\\hline \text { C. } & \text { randomised block design. } \\\hline \text { D. } & \text { matched-pairs model. } \\\hline\end{array}$
