The scatter plot shows the relationship between the test scores of a group of students and the number of hours they spend on social media in a week: A scatter plot is shown. The x-axis is labeled Hours spent on social media, and the y-axis is labeled test score. Data points are located at 0.5 and 100, 2 and 100, 1 and 95, 3 and 85, 3 and 78, 5 and 75, 5 and 72, 6 and 70, 6 and 98, 7 and 60. A circle labeled A includes all of the points except for the one at 6 and 98. Point 6 and 98 is labled B. Part A: What is the group of points labeled A called? What is the point labeled B called? Give a possible reason for the presence of point B. (3 points) Part B: Describe the association between a student’s test scores and the number of hours spent on social media. (2 points)
@hba @Loser66 @Compassionate please!!!
Generally speaking the correlation between the scores and amount time spent on social media is negative. More time on social media the lower the score.
I dont know of a name given to the points in the circle - they are the points which conform to the general trend. B is the exception
B might be called an outlier - i dont really know.
"high negative correlation"
oh my gosh thank you so much can you help with one more question??
and "isolated point"
The point B might be explained by the student being a 'natural' for the subject so he does not need to study so hard as the rest
