Answer those question: Questions 1. Is the research based on an observation study or a randomized experiment? How do you know? 2. What are the explanatory and response variables? Can “cause and effect” be concluded? 3. If it’s an observational study, give an example of a possible confounding variable (other variables that may also have an effect on the dependent or response variable). If it’s a randomized experiment, specify the treatments. Component 1: The source of the research and of the funding. Component 2: The researchers who had contact with the participants. Component 3: The individuals or objects studied and how they were selected. Component 4: The exact nature of the measurements made or questions asked. Component 5: The setting in which the measurements were taken. Component 6: Differences in the groups being compared, in addition to the factor of interest. Component 7: The extent or size of any claimed effects or differences. Summary: Are the results of the study convincing to you? If not, why not? If so, would you change anything in your life because of this study?
