Answer 1

The dot plot shows the number of pairs of shoes that the students have. The total number of students is 16. We would interprete the plot as follows

1 student has 8 pairs

2 students have 9 pairs each

4 students have 10 pairs each

2 students have 11 pairs each

2 students have 12 pairs each

1 student has 13 pairs

1 student has 14 pairs

2 students have 15 pairs each

1 student has 16 pairs

The median is simply the middle value. arranging the pairs, it becomes

8, 9, 9, 10, 10, 10, 10, 11, 11, 12, 12, 13, 14, 15, 15, 16

We can see that the two middle numbers are 11

Therefore, median = (11 + 11)/2 = 11

The correct option is B
