FALL 2022 OL Name 1. (19 points) A researcher is interested in the effects of providing verbal feedback on the time it takes people to solve puzzles. She uses both easy and difficult puzzles in the study. There are: A. two levels of puzzle complexity (easy and difficult) B. five levels of feedback frequency (no feedback, infrequent feedback, moderate feedback, frequent feedback, and continuous feedback) So, it is a 2 X 5 design: Feedback frequency (B) None Infrequent Moderate Frequent Continuous Puzzle Easy complexity Difficult [A) NOTE: The table above is just to illustrate the research design. There are nine subjects in each of the ten treatment groups. The dependent variable is the time to solve the puzzle. Using the information provided above and that in the table below, complete the table below for a two-way ANOVA. Show your work below the table and on other side of page. IN ADDITION - write the critical values of F (for a = .05) for each effect and indicate which effects are statistically significant. HINT: Do the degrees of freedom first!
