Discussion:
Propose a research design and explain whether this is a true experiment or a quasi-experiment
At this week's research team meeting, Rafael informs you that his hypothesis is now "Children who have high self-efficacy in softball are more likely to play baseball in a park district league." He thinks that the answer to this will help the park district to decide whether they want to include a beginner softball to their program but not as a feeder to their Little League baseball program.
To test his hypothesis, he decides to measure how children feel about their ability to play softball on the self-efficacy measure, ask them whether they played softball as a formal team or not, and then group them into children who signed up for park district baseball teams and children who did not.
Rafael's advisor asked him to propose a research design and explain whether this is a true experiment or a quasi-experiment.
