Research Data Critique Scenario Two



The CEO of ABC manufacturing commissioned a study to look at the differences between the current salaries of her employees (n = 474) and their starting salaries. The study collected current and beginning salary data for each of the 474 employees and the researcher conducted a statistic and the results are presented below. Using the five steps of hypothesis testing, explain what the researcher might have done, including the appropriate analysis, and interpret the results. Are there any problems with this study? If so, explain what they are.


Beginning salary mean = $17,016.09, SD = $7,870
