Question2. In a replication of a study in which map reading skills were investigated, 20 men and 20 women completed the original map reading task and the researchers obtained the following data: \begin{tabular}{|l|l|} \hline Male map reading scores & \begin{tabular}{l} $17,20,13,12,13,11,8,17,12,15,14$, \\ \\ Female map reading scores \\ \hline \end{tabular} \\ \hline \end{tabular}
The mean map reading score for both groups together was 12.23. a) What percentage of the male group scored above the mean score and what percentage of the femals group scored above the mean score? Show your calculations. [4 marky $$\begin{array}{l} 18 \div 20 \times 100=65 \% \text { men } \\ 6 \div 20 * 100=30 \% \text { women } \end{array}$$ b) Briefly explain one reason why it is important for research to be replicated.
