Read the article, Diaper Need as a Measure of Material Hardship During COVID-19 (byEmma Shaffer, Sallie Porter, Peijia Zha, Eileen Condon), and briefly answer thefollowing questions.

1. Did the descriptive statistic in the report sufficiently describe the major variables and background characteristics of the sample? Were appropriate descriptive statistics used - for example, was a mean presented when percentages would have been more informative?
2. Were statistical analyses undertaken to assess threats to the study's validity (e.g., to test for selection bias or attrition bias)?
3. Did the researchers report any inferential statistics? If inferential statistics were not used, should they have been?
4. Was information provided about both hypothesis testing and parameter estimation (i.e., confidence intervals)? Were effect size reported? Overall, did the reported statistics provide readers with sufficient information about the study results?
5. Were any multivariate procedures used? If not, should they have been used - for example, would the internal validity of the study be strengthened by statistically controlling confounding variables?
6. Were the selected statistical tests appropriate, given the level of measurement of the variables and the nature of the hypotheses?
7. Were the results of any statistical tests significant? What do the tests tell you about the plausibility of research hypotheses? Were effects sizable?
