DSRT 734: Comparing Employee Knowledge Before and After Training in JASP

DSRT 734 Question

A business with 50 employees wants to improve the product knowledge of
their workers. They tested each employee before (score1) a new training
program and after (score2) the training to test if their knowlege scores
were different. Save the following dataset to your computer and open it
in JASP. Perform the correct t-test to see if the scores for the
employees are different between score1 and score2. Copy and paste your
JASP output into your answer AND write your conclusion in APA format.

What this question assesses

This assignment assesses analysis of two linked knowledge scores for the same employees, including preservation of pairs, diagnostics on change scores, JASP output, and bounded interpretation of a training comparison.

How to approach this type of question

The missing dataset prevents any calculation. When it is supplied, verify that each row is one employee and that score1 and score2 are numeric measurements for that same person. Preserve the pairing during cleaning and examine missing values; the analyzed N is the number of complete pairs, not automatically the stated workforce size. Calculate or visualize within-employee differences, inspect their distribution and unusual values, and use those diagnostics to confirm the comparison method. In JASP, assign score1 and score2 as a linked pair, request descriptive summaries and the inferential table, and record the statistic, degrees of freedom, p-value, and relevant uncertainty. An APA plan should describe both occasions and the observed direction without saying that training caused a change unless the design supports that claim. It should also distinguish statistical evidence from the practical size of a knowledge change. No output values, conclusion, or employee scores can be reconstructed from the prompt.

Before running JASP, check identifiers and confirm that score1 and score2 were recorded for the same 50 employees. Review the distribution of within-person changes and investigate extreme differences. Save the analysis settings and record complete-pair N, both descriptive summaries, the inferential row, and any interval. Avoid selecting records or methods based on whether significance appears. The final narrative should report the actual evidence and limitations, not promise that the training improved every worker.
