The Art of Jumping Rope

By: Michael L., Andrew S., Andy …


Introduction

Introduction

  • In our Minute to Win It lab, we measured how many times a person could make a full rotation w/ a jump rope in 1 min. Our variables were blocked by gender, whether or not the person ate breakfast and whether or not the person played any sports.

  • Some outliers were expected but not many came up and only in specific situations

  • Skill w/ jump rope also a key factor

Quantitative Data

-slightly right skewed

-spread 19-166

Quant. Data Cont.

IQR – 89

Mean – 86.42

Median – 79

Min – 19

Max – 166

Normal Prob. Plot

-Data follows the line across, therefore it is normal

Gender Display

-Female center is smaller than male center (78 and 83.5)

-Spreads very similar (126F, 124M)

-The only outlier would be the 166 RPM in the girls plot, exceeding everyone else

-Gender doesn’t seem to change too much


The art of jumping rope

Sports Display

-Spread much higher for people who play sports

-Centers (63.5N) and (92Y) are also far apart showing the difference of playing sports

-Positive influence of playing sports on jump roping

-One outlier for the non-sport people (exceeding expectations)

Sep. Partner Data

-IQR’s (72M) and (107.25A)

-Spread is very close as well

-Centers are the main difference (71M) (119.5A)

-Some significant difference in either the test taker or the instructor

Two-Way Table

-This table is very complicated

Marginal Distributions

Sports

38.7% 61.3%


The art of jumping rope

Marginal Distr. Breakfast

32.3% 67.7%

Conditional Distr.


The art of jumping rope

Indep. Categorical Data

Sports v. Breakfast:

-P(AПB)= P(A)x P(B) (overlap/total)

-(A)= no sports (B)= yes breakfast

-7/31= (12/31)x(21/31)

-.226= .2622

-2nd test

-(A)= yes sports (B)= no breakfast

-5/31= 19/31 x 10/31

-.1613= .1977

Both roughly the same gap between answers showing consistently in the testing. The numbers aren’t close enough together to call them independent, thus making them two dependent variables.


Conclusion

Conclusion

-All in all the test came out a success

-Trends showed that people who ate breakfast and played sports were more successful with their jump roping. It was only a slight win however.

Possible Error or Bias?

-Subconsciously giving friend a few extra jumps

-Losing count (even w/ tallying the paper)

-Not starting the timer soon enough

-Inability to keep up w/ jumper’s pace
