Transcript of Sport Practice Vs. Homework Time

Sport Practice
VS
Homework Time By:Victoria Gutowski and Denise Hallstrom Methods and Results Conclusion There is a correlation between the two variables. It is the more time someone spends time at a sport, the less homework that gets completed. Table Survey Independent Variable:
Time at Sports (hour)

Dependent Variable:
Time on Homework (hour) Hypothesis: Question: INTRODUCTION Does the amount of time spent at a sport affect the time spent on homework? If someone spends more time at a sport, then the amount of time someone spends doing homework will decrease. We administered a survey to 21 male and female students at Trumbull High, from all grades and different sports. We asked a number of questions including 'How many hours a day do you spend at a sport?' and 'How many hours a day do you spend on homework?' Linear Regressions Equation Interpolation:
y=-.04x+1.7
y=-.04(.65)+1.7
y=1.7 People can use the results that come out of the current data. Teachers can use it to see why students are not doing their homework and parents can use it to see if sports are invading too much on their child's education. Importance This study of sports and homework is important to us because we both do competitive sports and are struggling with the amount of homework given each night. We wanted to see if other peers who did sports were spending a lot of time on their homework or their sport. Graph y=-.o4x+1.7 Your homework time is starting at 1.7 hours, decreasing by .04 hours for every hour you spend at a sport Interpretation X intercept 42.5 Figure 1 Figure 2 Figure 3 This is not meaningful in the context of the task because the answer does not fit into the context of the problem. Correlation Coefficient The correlation coefficient is -.074. The correlation is negative and weak between the two variables. Extrapolation:
y=-.04x+1.7
y=-.04(9)+1.7
y=1.3 The answer is 1.7. This data represents interpolation because it fits inside of the data. At the beginning of the task, we asked ourselves a question. The amount of time someone spends at a sport does affect the amount of time someone spends doing homework. The answer is 1.3. This data represents extrapolation because it does not fall into the current data.
