Question

Student ........ has the smallest variation in the number of hours of screen time per day.

Answer 1

Answer:

Student G.

Step-by-step explanation:

This is a box and whisker type of diagram. There is a little dot for each row. This suggests the mean amount of y for each x. In this case, x is the students and y is the amount of screen time per child. The lines above and below the little dot shows the variation in data. The bigger the lines and the further away the end of the lines from the center i.e. the mean, higher is the variance and the spread. In this case, the student with smallest variation has to be identified. It can be seen in the graph the the student G has the shortest lines above and below the mean point. This means Student G has the smallest variance!!!

Answer 2

Answer:

Student G.

Step-by-step explanation:

We have been given a diagram, which represents the average number of hours of screen time per day for each student.

We know that variation is the measure of dispersion of a data set. A wide set will have more variation than smaller data set.

We can see that the smallest data set is average number of hours of screen time per day for student G, therefore, student G has the smallest variation.
