Question

Sam conducted a survey at lunchtime to find the number of hours that students spent studying for the science test. He asked 15 different students how much time they spent studying. Sam drew a line plot of the data. His plot has a spread of 2.25 and peaks at 1.75 hours. which graph line plot did same draw?

Answer 1

Given:

Spread of data = 2.25

Peak = 1.75

The spread in a data plot is the measure of distance between the numbers in a data set and the median.

The peak of a data can be said to be the the point where the data value is greater than other data values.

Let's determine the correct graph using the peak of the data.

From the list of graph line plots given, option C has a peak of 1.75 because 3 students spent 1.75 hours which is the time with the highest number of students.

The graph in option C peaks at 1.75 because the greatest data value is on 1.75.

Therefore, the graph in Option C is the graph line Sam drew.

ANSWER:

C
