How was the sample data collected? (Such as surveys, interviews, test scores) and by what sampling technique (such as random samples, stratied samples, etc.). Include any other information you think is relevant for describing the study. What type of statistical summaries did they discuss? How was the data analyzed? What tests did they perform? (List a few that are mentioned, you do not need to know what they all are unless we discussed them in class.) Are you able to identify the hypotheses? Explain the meaning/implications of the p-value(5) for this study. Check the results for misleading graphs or statements
