The table shows the number of teachers in the cars. \begin{tabular}{|c|c|} \hline $\begin{array}{c}\text { Number of teachers } \\ \text { in one car }\end{array}$ & Number of cars \\ \hline 1 & 3 \\ \hline 2 & 4 \\ \hline 3 & 6 \\ \hline 4 & 2 \\ \hline \end{tabular} a) What was the modal number of teachers in a car? b) What was the median number of teachers in a car? c) What was the mean number of teachers in a car?
Solution
Step 1 ：Find the mode by looking at the highest number of cars for a given number of teachers in one car: \(\text{Mode} = 3\)
Step 2 ：Find the median by ordering the dataset and finding the middle value: \(\text{Median} = 3\)
Step 3 ：Find the mean by dividing the total number of teachers by the total number of cars: \(\text{Mean} = \frac{37}{15} \approx 2.47\)
Step 4 ：\(\boxed{\text{Modal} = 3, \text{Median} = 3, \text{Mean} \approx 2.47}\)
