Correlation Project By: Storm Miller Brett Beaune and Gunnar Morrall Hint: Not Ours

Hypothesis Statement: We wondered if there was any correlation between time being active and time using electronics So is there a correlation between time being active and time using electronics?

The two coordinate pairs we chose were (300,30) and (30,300) The two coordinate pairs we chose were (300,30) and (30,300). So using rise over run our slope was -1. 300-30= 270 =-1 30-300= -270 And with y-intercept our b value is 330

With our line of best fit we figured out our slope intercept formula was Y=-1x+330

Lets just say somebody spent 17 minutes of using technology according to our formula how much physical activity did they do.

So according to our formula (Y=-1x+330) If some one spent 17 minutes using electronics they would spend 313 minutes of exercise We got this answer because we substituted 17 for x. 313=-17+330

We found a weak, negative correlation in our study! So starting at 330 minutes of exercise for an average middle school student, they would lose a minute of exercise for every minute using electronics
