using this link answer the questions below ( https://www.mdpi.com/1074962)

1. What was the central research question/hypothesis/purpose of the study?

2. What method did the researchers use? What were the independent and dependent variables (if applicable)?

3. Who were the participants? (how many? demographics? inclusion criteria?)

4. What type of data was collected?

5. How were these data analyzed? *Because some of the statistical analysis procedures a very technical, and there are many that I did not cover in the lecture, you can simply answer 'The researchers used statistical procedures to analyze the data'. If the study was qualitative, however, then statistical procedures would not have been used, in which case you can say, 'The researchers used a thematic analysis to analyze the data'.

6. What were the main results of the study?

7. What did the researchers conclude?

8. Provide an assessment of external and internal validity.

Reminder for answering #8:

To assess external validity, you analyze the sample of participants to determine the generalizability of the results. How representative was this sample? Large, diverse samples increase external validity. Small, homogenous samples decrease external validity. Your answer should be formatted like this: The external validity of this study was relatively (high or low) because ...

To assess internal validity, you analyze how confident we can be that the results are due to what the researchers say they're due to. Were there any confounding variables? Well controlled studies that prevent the influence of confounding variables have high internal validity. In studies when you can think of many possible confounding variables, there is low internal validity. Your answer should be formatted like this: The internal validity of this study was relatively (high or low) because ..
