Closed circles are arranged vertically over the numbers on the number line. The following data are shown: 0 pets, 4 dots; 1 pet, 7 dots; 2 pets, 4 dots; 3 pets, 2 dots; 4 pets, 1 dot; 5 pets, 2 dots; and 6 pets, 1 dot.


Estimate the median of the data in the dot plot.

(1 point)

Answer 1

There are 4+7+4+2+1+2+1 = 21 data values, so the median is the (21+1)/2 = 11th value. Counting up the dots: positions 1–4 are 0, 5–11 are 1. Thus the 11th value is 1.

Median = 1 pet.
