Based on social media survey data, the marketing compiled an overall rating scores for each of their bikes. The survey also contained ratings on many bike components, and GBI marketing would like to assess whether a relationship exists in the scores of three relatively inexpensive bike components (brakes, handlebars, and saddle) and the overall bike scores. The idea is that these components could be swapped at little to no costs if it would improve the overall bike rating scores.

In the attached file, each score represents the percentage of respondents who rated one of the three independent components (brakes, handlebars, and saddle) as excellent or very good. The overall scores for each bike are also included in the file. For example, the highest ranked bike, the Deluxe Road Bike (Shimano), had an overall score of 94.3, and component scores of 94.5 (brakes), 90.8 (handlebars), and 97.7 (saddle).
