Students were asked to produce a 1-2 page double-spaced report summarizing their findings:
- A brief summary of the data in each mini-study (Solon neighborhood and CR/IC). This included a response to the following question using data, graphs, regression lines, significance tests and correlation coefficients to backup your opinion - "Is size a useful predictor of price in your neighborhood? ...and in Iowa City or Cedar Rapids?"
- A prediction of the students' house's assessed value based on square feet using his/her neighborhood model and the Iowa City or Cedar Rapids model. Does this match-up with the assessed value according to the websites? Explain a few possible reasons why or why not.
- Finally, include a paragraph explaining any possible errors observed in the way data was collected or the process in which this study took place
Scatterplots, regression line equations and prediction intervals using Microsoft Excel were the norm for each student.
This project parallels quadrant D learning as written in the 9-12 Data Analysis/Statistics & Probability Iowa Core Curriculum essential concepts.
