Sample Question 19:
Step 1: Look at the graph, you can see the distribution of the number of children in each family.
Step 2: Count the total number of families. In this case, there are 13 families in total.
Step 3: The median is the middle number of a sorted list. As there are 13 families, the middle number is the 7th in either direction (from the left or from the right).
Step 4: It's easier to count from the right side. Starting from there, you can see that the 7th family has 4 children.
So, the median number of children in the family for this distribution is \(4 (\text{D})\).
The graph shows the distribution of the number of children in the families of the students in Ms. Jordan's English class. The median number of children in the family for this distribution is
\(\text{(A)}\ 1 \qquad \text{(B)}\ 2 \qquad \text{(C)}\ 3 \qquad \text{(D)}\ 4 \qquad \text{(E)}\ 5\)
