The "Perfect" Date: Ranking and Rating Decisions with a Spreadsheet
In this Spreadsheet Across the Curriculum activity, students will build a spreadsheet to apply a ranking and rating scheme using weighted averages to help them decide which person to date. In the activity they will explore the difficulties involved in rating systems. One of the main issues is to decide how to measure and rank the quantitative and qualitative factors that affect their decision.
- Explore difficulties involved in measuring and rating qualitative data.
- Rate certain attributes according to their own personal preferences.
- Assign weights to these attributes.
- Use an equation for the weighted average to perform a calculation in Excel
- Use the sort function in Excel.
- Gain experience with Excel equations.
- Gain experience with weighted averages and how they can apply to real-life situations.

For the class overall, I will use a student attitude survey at the beginning and end of the semester. The survey, which focuses on self-confidence, value, enjoyment, and motivation, is part of the Colby-Sawyer Quantitative Across the Curriculum project
