Research Proposal I (20 Points)
A researcher prepares three types of situations to test anxiety among a group of patients being treated for various anxious tendencies. The dependent variable is a paper and pencil anxiety test on an interval level of measurement. Scores can vary from 0 to 40; the higher the score, the greater the measured anxiety. Each patient will receive each condition once.
