Kecoughtan High School AP Statistics students culminate their year with projects
Students in Laura Yannarella’s Advanced Placement (AP) Statistics class ended their year with some phenomenal projects. The projects included a hypothesis, collection of data, and a five-minute PowerPoint presentation to the class.
Students used the methods of inference learned this year to investigate possible connections in a subject of interest to them. Project proposals included a wide variety of topics, such as:
- Senioritis: will your GPA suffer?
- Are females better at recognizing celebrity couples than males?
- Do women and men pay different prices for clothing?
- Are the large fries really worth it?
- Which gender performs better on gender-based questions?
- Does handedness and GPA have an association?
- Does an iPhone know it’s owner’s song preferences enough to skew the randomness of a shuffle?
- Does coffee have an impact on GPA?
- Are people more prone to overestimate the length of a short song clip due to a tendency of impatience?
- Does the presence of a median subconsciously cause drivers to speed more?
Students submitted a proposal of their topic of interest and then designed a study to collet data, analyze the data using any of several inference techniques learned in class, then presented their proposal to classmates through a slide show.
Miriam Abdel-sayed, who studied whether being right- or left-handed had any effect on GPA concluded that handedness has no effect on a high school student's GPA. She said, “The reason I picked it is with me being left handed, people always told me left-handed people are more creative thinkers and I wasn't sure if it was myth or fact. I was curious to see if it had any effect on a student's academic achievement.”
Rebecca Brown and Christian Skaggs hypothesized that Christian’s iPhone has a sense that he preferred to hear Cardi B songs. They ran 50 simulated shuffles and found that it did indeed appear that his iPhone played more Cardi B songs than other artists. The students said, “We learned how to put statistics into an actual situation that we related to.”
Senior Bailey Espaillat’s project tested whether people have a natural tendency to be impatient. She had people listen to a 12 second clip of music and then asked them how much time they believe had elapsed. She said, “When we were introduced to the project, something that interested me was the idea that people tend to overestimate the length of a clip when played. This was a great opportunity to see if that theory held up statistically.”
Students were interested in age-old beliefs that males and females are different. Saja Carpel, Chet Davis, and Keliandra Rossi ran a test on gender specific questions such as make-up tips and knowledge of car maintenance to see if gender knowledge crossed over between the sexes. Their conclusion: while both females and males were more successful on questions geared toward their gender, both sexes performed roughly the same on questions based on the opposite gender.
Chauntanay Thorpe wondered if there is a difference in which gender eats breakfast more. Her conclusion: There is evidence to say that gender has an effect on whether students eat breakfast or not.
Jessica Law and Haley Crabtree ran a test on which gender knew more celebrity couples. Their conclusion: females outperform males.
Regan Walther and Samantha Whippo tested the belief that females compare themselves to others more than males.
Tori Dixon and Gabrielle Poffenbarger were interested in whether females do take more time to get ready in the morning than males. Gabrielle said, “I learned that it's harder to gather data than I thought it would be.”
Malik Miller’s found that male and females both prefer the same movie genre on a first date. He said of his project, titled Kiss or Kill, “The stereotype is a lie that more girls would rather see a romantic movie on their first date.”
Juniors Summer Kujawa and Wyatt Slatter did an analysis on whether having a median between opposing lanes of traffic caused a higher proportion of speeders. They received permission from the Hampton Police Division to use a radar gun on Nickerson Blvd and Fox Hill Road to measure the proportion of speeders in the first 50 cars to pass them on each road. They concluded that it does appear people speed more in the presence of a median. Summer and Wyatt said, “We were just curious to see if people would speed more if a median is present and we used statistics to implement this in a real life situation.”
Juniors Jessica Laxton and Mallory Matthews made a Kahoot game to see which was more recognizable – cartoon characters or historical figures. Not surprisingly, cartoon characters won. They said, “I thought it was fun being able to prove the theory that 5th graders know more cartoon characters than historical figures. It was something we all assume; now we have the statistics to prove it.”
