1. Does the amount of sports you play in a day effect your math grade?VS

2. Hypothesis
There is a strong positive correlation between the hours of sports played in a day and your math grade.

3. Sports (hrs in a day)
Math Grade (%) 4 93 2 74 97 1 87 83
1.5
100 98 3 91 99 89 85 6 94 95 96
2.5 97 1 86 4 96 76 3
100 99 2 95 88 92
1.5 89 5 81 98 3 95 1 98 96
0.5 92
102 2
100 89 86 97 4 99
1.5 82

4. All of our group members were present when data was collected.

5. Line of best fit equation
x1 y1
(1.5, 89)
x2 y2
(5, 100)
= 11 =
Y= 100
X= 5
M= 2.4
B= 88
100 = 2.4 (5) +b
100 = 12 +b
88 = b
= 2.4
Y = 2.4x + 88

6. So… how do we predict points not on our scatter plot??
Let’s say that someone plays 7 hours of sports, on average, each day.
(Does he sleep?)
In addition (no pun intended) we polled people by going around, as a group, and asking everyday middle school students (6-8 grade).
Y = 2.4 (7) + 88
Y =
Y = 104.8

7. Summery of Student Behavior
We have concluded that as the hours of sports that you play in a day increases, so does your math grade.
KEEP PLAYING THOSE SPORTS! =
