Which test are you using?
What are your H0 (null hypothesis) and Ha (alternative hypothesis)?
Calculate your statistic.
What decision does this inform you to make and why? (You may use the critical value in the chart or the calculated p-value, but you must indicate what you are doing.)
Write a one to two sentence conclusion that correctly responds to the question. Use APA format to report your statistic ex. [χ^2(df)=1.1, p<.05]
Mr. Jones and the New Worksheet
Mr. Jones wanted to check if there was an observable impact of a particular worksheet on his students’ test scores for Chapter 1. His idea was to test if there was a significant variation in the average test score of the class that used the worksheet in comparison to the class that did not. In the class before lunch, he used the worksheet but not the class after lunch. He has 23 students in each of the two classes. Their test scores are below:
Before Lunch | After Lunch | ||
86 | 79 | 23 | 67 |
59 | 45 | 74 | 46 |
98 | 67 | 38 | 90 |
81 | 80 | 14 | 79 |
32 | 72 | 38 | 63 |
35 | 84 | 51 | 38 |
31 | 60 | 18 | 56 |
57 | 20 | 44 | 70 |
68 | 43 | 27 | 33 |
24 | 16 | 16 | 14 |
31 | 58 | 24 | 30 |
