A researcher is interested in testing the effect of two techniques— (1) attending small-group tutoring sessions and (2) reading guides—on a person's ability to do a particularly challenging form of crossword puzzle known as a cryptic crossword. The researcher recruits 36 participants and has half of them attend a small-group tutoring session. They also have half of those who did and did not attend the small-group tutoring session read a cryptic crossword guide. They then gave the 36 participants a cryptic crossword puzzle and recorded how many clues the participants had answered correctly after 20 minutes. The data for the researcher's study is included below. 1. Paste the necessary output for this analysis (both descriptive and inferential) from jamovi. Descriptive statistics must include cell means and group means 2. What is the mean and standard deviation for each group ? 3. What is the value of the test statistic for each effect ? 4. What is the degrees of freedom for each effect ? 5. What is the precise p-value for each effect as reported by jamovi ? Make sure you report each value to at least three decimal places. 6. Which of the effects are significant? ? 7. What is the effect size for each effect ? 8. Based on the results of your analysis, does tutoring increase, decrease, or have no effect on cryptic crossword ability ? 9. Based on the results of your analysis, does reading a cryptic crossword guide increase, decrease, or have no effect on cryptic crossword ability ?
