Critiquing A Quantitative Study
ANSWER
When critiquing a quantitative study, it is essential to consider various factors such as research design, sample size and selection, data collection methods, reliability and validity of the data collection, and statistical analysis.
Research Design: The first factor to consider when critiquing a quantitative study is the research design used. Is it an experimental or non-experimental study? How were the variables measured? Were experiments conducted in a controlled environment? Was the sample size large enough to support generalizable conclusions? These are all critical questions to ask when assessing the research design of a quantitative study.
Sample Size & Selection: Sample size and selection are other factors when critiquing a quantitative study. Was a random sampling method used? Was the sample size large enough to draw reasonable conclusions? Did the researchers include participants that represented the target population accurately?
Data Collection Methods: It is essential to consider the methods used. How was data collected? What instruments were used? For example, if interviews were conducted, how were questions structured, and what questions were asked? Was the instrument valid and reliable for measuring these variables?
Reliability & Validity: It is also essential to assess whether or not the data collected is reliable and valid. Were valid measures used to capture information about each participant in an accurate way? Was there any bias in how data was collected or analyzed? Have similar studies found similar results when using similar methodologies?
