## Color Preference Analysis

Type: Mini-lesson

Theme: Statistics

Grades: 6, 7, 8, 9, 10, 11, 12

Learning Target: Students will produce color preference data and create a method to analyze multidimensional data.

Instructions
1. Using student-created data (use an online Form generation tool), generate a table of r, g, b data that describes student color preferences (in RGB color, 0-255) and dislikes. Use this tool to create the colors. Collect favorite and list favorite color data. Data should be formatted in the following manner:
 ID R G B 1 34 255 123 2 255 250 27 3 0 255 55
1. Copy and paste the data into these two graphs: Most Favorite, Least Favorite. You will need to delete the existing data table and rename the variables: i1,r1, g1, b1. The i variable is the ID from the data table.
2. Share both the spreadsheet and the Favorite graphs to student groups. Have groups answer the following questions:
1. Is there a pattern to most and least favorite colors in the class?
2. How can you prove the pattern using the data?
3. If there is no pattern, can you prove that using data?
3. After students have developed a method for their data analysis, ask students to use histographs with R, G, and B color data and look for a pattern. Answer the following questions:
1. Would using a scatterplot show a pattern?
2. What is one problem with using a scatterplot?
3. What other method could be used?
