Question

Mr. Roger Munson, the owner-manager of a construction company, is skeptical about investing in training for his 50 construction employees. He believes the investment might be wasted if the newly skilled employees are quickly poached by other companies, and he doubts the training will yield significant productivity improvements. Nevertheless, a performance management consultant argues that enhancing employee skills will boost productivity and positively impact the company’s bottom line. Reluctantly, Mr. Munson has agreed to allow the consultant to conduct a study involving the training of all 50 employees. Providing the training services pro bono, with payment contingent upon demonstrating, through empirical evidence, that the training results in significant productivity gains within a three-month period following the training. Table 4.1 presents an excerpt of the evaluation comparing each employee’s productivity before and after the training. Employee productivity was measured as a percentage of target output achieved over a defined time period, with performance assessed against set benchmarks.

REQUIRED:

Identify and justify the research design underpinning the study, using supporting evidence from the
provided data.


Identify the independent variables (IV) and the dependent variable (DV) in the study, clearly state the
main research question, and formulate both the null and alternative hypotheses. 


Using the standard reporting format, provide a comprehensive interpretation of the results of the
inferential analyses presented in Figures 4.1 to 4.4. In your interpretation, include an analysis of TWO
limitations of the study, discussing their potential impact on the findings, and recommend whether they
should receive payment for the training services provided, substantiating your response with relevant
evidence and reasoning.
