The bar graph shows the relation correlation between the number of hours spent on televison in each day, and science test scores by Grade 8 8th grade students.
From the data, we recognize that there were significant relation correlations about leisure time and test scores. First, we can see the group of students who did not watch television averaged an estimatedly got of 76 points in the science test, and the following group was had the highest scores, group at who averaged 80 points, in which they was spent the least amount of time (about less than one hours time) to watch television. Not surprisingly, the scores of the group who spent two hours to watching television group was slightly lower than before, and got about 78 points. Significantly, students who spent on three hours got a the same scores as students who did not watch television. In the following groups, four hours, five hours, and more than 6 six hours respectively estimatedly got 74 points, 71 points, and 65 points.
Overall, the students who watch one hours of television got the toppest highest scores than any others the rest, and students who spent more time on watching television got a lower scores except who did not watch it .
