For my project I used the variables height vs. distance. My question is: Does our height affect how far you can jump? I got this idea from track because I did long jump and I wanted to see how far people, from our math class, could jump.
In my project I used the tallest, medium, and shortest people who were willing to jump. (Tall Person 1-2, Medium Person 1-2, Short Person 1-2) After I had gotten the people, I asked for their height. After their height was recorded they had to jump from a line outside and see how far they could jump. Then I measured how far they jumped from that line to where they landed and measured from their heel.
My prediction was that the tallest person would have the advantage of jumping farther because they can grab speed fairly quickly and have longer legs. Then again the weight of the person can interfere with the distance but I am not going to go there. The shorter people can get a pretty fast speed but their legs are also very short and you really have to get your legs out in front of you as far as you can. The speed and how far you can put yourself out in front of you is the key to getting far and I think the tall people have that advantage.
Numbers:
| TP1 (5" 7) | 10 | 9.8 | 10.6 | 10.8 |
| TP2 (5" 5) | 7.5 | 7.8 | 8.1 | 6.8 |
| MP1 (5" 2) | 4 | 4.1 | 4.3 | 4.6 |
| MP2 (5" 2) | 9.3 | 8.7 | 9.3 | 10.8 |
| SP1 (4" 11) | 8 | 8.1 | 8.1 | 8.3 |
| SP2 (4" 10) | 5.4 | 5.3 | 6 | 5 |

Words:
My prediction about tall people jumping farther than others, in this case, is correct. I also thought that your height depended on how far you can jump which was wrong because as you can see in my numbers category that short person number 2 jumped farther than medium person number 1 and medium person number 2 jumped farther than tall person 2! Great job guys!!!
Why did you choose to use a bar graph to represent your data? What makes this the best choice?
ReplyDeleteI really didnt understand which graph to use. I just understood the point of a line gragh and I think I will change it to a line graph because there are things u need to consider between the points.
ReplyDeleteI think you should have used some eight graders too. They could have been the same height and you could have had more stable information
ReplyDeleteThis was a nice and organized project. I really unnderstood what the two variables were. And I like the reason why you choose the project

ReplyDeleteI didn't have any 8th graders to use. I knew some but I couldn't find a time where I could have them jump but track and we were all preparing for a meet and I also had to practice my jumping at that time.

Thank You.
