1. Provide a 1-paragraph summary of the article in your own words.2. Discuss any relevant issues of validity and reliability.Conclusion- Internal validity →construct validity →external validity. Innovation is needed.“In terms of conclusion validity”.. there might be some issues of sample size.. look at the slides and explain everything of sampling error. Relationships of data/ correlationsInternal validity. experiment/ quasi/ non experiment. Single group?- single group threat. History threat/mortality threat/ testing threat. Two groups or more/ selection history threat/ selection mortality/ social threats to internal validity★ (possible interactions between treatment and control-e.g. imitation of treatment..)External validity: Sb do the probability sample- so you could generalize the sample to certain type of populationConstruct validity applies to everybody. Since there is a survey.- Inadequate preoperational explanation of construct (definitions of variables in your study is comprehensive/ clear enough? Be clear of what you are going to measure)- Mono-method bias, (e.g. if self esteem have 5 dimensions ,you are only including 2.)- Mono operation bias – quasi/ experiment, refers to the implementation of treatment. Do you have problem with how the treatment is implemented? Did the residents actually get the food(treatment) are you giving the program or not. If non experiment, do not talk about this since there is no treatment.- Social threat to construct validity.(non-sampling error) and how concerned we are with the study. If it is a sensitive issue. There will be non-sampling error, no trust, be shamed of the answer, e.g. income is also a sensitive issue. Face to face interview is risker. Is the author convincing you there is a good data?3. What are some strengths, benefits, and limitations of this study? What different methodological choices could the authors have made? Would you do anything differently if you conducted this study?
