Question

A few months ago, the upper management at a large corporation decided they wanted to make major changes in the organization. Leadership is concerned that employees may be resistant to the change, and they want to find out if there is a change management method that would help employees accept change more effectively and keep employee satisfaction high. Two methods they have considered are the ADKAR Framework and the Prosci Change Management Methodology. The company wants to implement a small change in two departments before they make any major organization changes and would like to test the methods. The corporation uses the Devine Company to measure employee satisfaction with an anonymous survey.

• • What is the significance level of the comparison?
  • What was the alpha level you identified in Week 3?
  • What was the means and variance for each variable?
  • What was the test statistic?
  • What was the critical value for both the one- and two-tailed test?
  • Was your test one-tailed or two-tailed?
  • Were you able to reject the null hypothesis? In other words, did you prove there was a difference?
• Talk about what these results mean in everyday language and in context to your chosen scenario.

Answer 1

The significance level is 0.05.

Note: Please provide alpha from Week 3 to answer the second question

The means and variance for each variable are:

ADKAR Frame work: mean = 4.875 variance = 5.267857143

Prosci Change Management Methodology: mean = 8 variance = 18.28571429

The test statistic is -1.821237697

The critical value for the one-tailed test is 1.761310136

The critical value for the two-tailed test is 2.144786688

Our test was two-tailed.

We are able to reject the null hypothesis for the one-tailed test not for a two-tailed test because the absolute value of the test statistic is less than the critical value for the one-tailed test but not less than the critical value for a two-tailed test. Hence, there was a difference in a one-sided test.

It can be concluded that both methods help employees accept change more effectively and keep employee satisfaction at a similar level.
