My hypothesis
More older girls have their ears pierced than younger girls.
The predictor
Age of the child

Age of Respondents

Statistical Measures

Median: 15
Mode: 14
Mean: 14.92, Std. Dev.: 3.3

The outcome
If their ears are pierced

Are Their Ears Pierced?

Statistical Measures

Mode: yes
Interpretation
I found out that for the younger age group (15 and under) there were 5 yes answers for ears pierced per every 1 no answer. In the older group (16 and up) there were 3 yes answers per every 1 no answer. This means that there were more younger people with their ears pierced than older people.

Statistical Measures

T-test statistical tests can only be used when you are comparing one categorical variable (with two groups or categories) and one continuous variable. You need to choose a statistical test that is appropriate for your predictor and outcome variables. If you need more help, you can revisit the SmartGuides or you can email a mentor for help.

Evaluation
The data did not support my hypothesis. I thought that more older respondents would have their ears pierced as compared to younger respondents. But, I found out that there was a 5/1 (5 to 1) ratio of yes to no answers for younger respondents, and a 3/1 ratio of yes to no answers for the older respondents. This doesn't support my hypothesis.
Summary of findings
I found out that more younger kids had their ears pierced than older kids. This actually suprised me! I think it just depends on if they wanted their ears pierced or not, but I could be wrong. Also, it could've just been the time they grew up-what was in and out.
Conclusion
I think it would have been cool to see if age affects how many ear piercings some people have. Like, to ask "Do you have single, double, triple, etc. pierced ears?" would be interesting. I would think older kids have more double piercings than younger kids. These would be interesting questions.
