[Solved] The following data show the results from an independent-measures study comparing two treatments. a. Compute the independent-measures t statistic
Question: The following data show the results from an independent-measures study comparing two treatments.
| a. | Compute the independent-measures t statistic for these data. | ||
| b. | Compute the percentage of variance explained by the treatment effect (r 2 ). | ||
| c. | Convert the data into a form suitable for calculating the point-biserial correlation, and compute the correlation. (You should find that squaring the point-biserial correlation will produce the same r 2 value that you obtained in part b.) | ||
| Treatment | |||
| I | II | ||
| 1 | 4 | ||
| 6 | 11 | ||
| 6 | 10 | ||
| 3 | 7 | ||
| M = 4 | M = 8 | ||
| SS = 18 | SS = 30 | ||
