### A survey was made among students in a district and the scatter plot shows the level of reading and height for 16 students in the district. Describe the association and give a possible reason for it.

Correct option is (d)

When the level of reading is 2, heights of student is 50 inches

When the level of reading is 5, heights of student is 55 inches

When the level of reading is 7, heights of student is 60inches

When the level of reading is 6, heights of student is 45,55,60 inches respectively.

The graph shows when level of reading increases heights of students also increase , which means the garph is positive but for same level of reading there are more than one students of different heights which the association is non linear
