Question

A researcher wanted to know if there was a difference in the effectiveness training results between permanent employees at a business and temporary employees at the same business. The two training methods were in-person training or via videos. After the training, each employee took a test to determine the effectiveness of the training. Draw the correct design for this experiment. (Hint: In the design, it is easier to start off with the training methodology.) Remember to clearly indicate what is randomized.

Answer 1

solution: Let, .) Statistical model to compare the a means from a independent Populations. 1. Test score Training methods Video training An Persontraining Mean score ! Test score of permanent employees of a business test scores of temperory employees of the same business mean score 2 → This is a pooled variance t test model with two independent random variables of the test score of permanent and temperory Employees, and test scores measured in two of the training methods. → one is video training and another one is in-person training. a compare the means of two independent samples of the test scores using poded variance t test to determine the difference in the effectiveness of the training results of the permanent and temporory employees. → If you do two way analysis of variance, you will the Conditional means with the trainingmethods in two levele two levels. and test come in

a) Then the four mean values will be compared to determine the difference blw the employees given that either they attend in-person training Bu video training.
