The Art of Jumping Rope By: Michael L., Andrew S., Andy …
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
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%
Marginal Distr. Breakfast 32.3% 67.7%
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 -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
