We discussed correlations and their use in class. You showed high levels of proficiency in the various examples and samples which were shared in class. Your second reflection focuses on developing a small, but relevant, data set from the teacher evaluation data for your school. Begin the exercise by contacting the principal or assistant principal (or data clerk) in charge of submitting the teacher evaluation data to the central office. Request the evaluation records for the teachers at your school (including your own if applicable) and then populate an Excel spreadsheet with the information.
