Question

The dot plot and box plot show different displays of the ages of runners on a track team

Answer 1

Answer:

- Add the number of dots above each age in the dot plot to find the number of players on the team: 2 + 1 + 3 + 2 + 3 + 2 = 13.

- The median appears clearly on the box plot at the line within the box: 10.

From the dot plot it notices that

Age                        frequency

   7                                  2  

   8                                  1  

   9                                  3  

 10                                  2

 11                                   3

  12                                  2

Total :                           13

Add the number of dots above each age in the dot plot to find the number of players on the team: 2 + 1 + 3 + 2 + 3 + 2 = 13.

From the box plot it is noticed that :
