A) What are the degrees of freedom for this study?

B) What is the mean of the difference scores (MD)?

C) What is the sum of squares of the difference scores (SSD)?

### Scenario 1: Participant Scores The table below presents data for three participants, each with two scores recorded under conditions defined in Scenario 1. This data aims to illustrate changes or differences between two sets of conditions represented by "score 1" and "score 2" for each participant. | Participant | Score 1 | Score 2 | |-------------|---------|---------| | 1 | 75 | 43 | | 2 | 61 | 39 | | 3 | 68 | 74 | **Explanation and Analysis:** - **Participant 1**: Shows a notable decrease from Score 1 (75) to Score 2 (43). - **Participant 2**: Also experiences a decrease from Score 1 (61) to Score 2 (39). - **Participant 3**: Contrarily, Participant 3 exhibits an increase, moving from Score 1 (68) to Score 2 (74). This table can be used to discuss data trends, patterns of change, or the impact of varying conditions on performance outcomes within the educational context. Further analysis can explore the factors contributing to increases or decreases in scores.
