In frank113/cmu202: Necessary Packages and Data for 36-202 at Carnegie Mellon University

Description

You often hear that a negative outlook can be self-defeating. To test whether this is really true, psychology researchers conducted a study in 1990 on a group of 33 swim-team members at the University of California at Berkeley. 16 of them are cataloged in this data set.

Usage

Format

A dataframe with 16 rows and 2 columns.

Pessimism

The pessimism score of each swimmer. A high score indicates a more pessimistic mindset.

Ratio
