he ANOVA determines whether any significant variance exists between two or more sample groups regarding a specified dependent variable. Determining the level of variance gives you an opportunity to conduct additional tests to ensure that your findings are accurate and sufficiently supported by your data. Unlike t tests, an ANOVA can compare more than two groups. For example, an IT manager wants to determine whether the mean (average) times required to complete a certain IT task differ based on the three types of employee training. He randomly selects 10 employees who have undergone the three types of training. Using an ANOVA, he could analyze data to verify whether the mean times required to complete the same IT task varies based on the three types of training.
This week, you will run a one-way ANOVA using appropriate data from the IT Security Dataset located in this week’s Learning Resources.
To prepare for this Assignment:
Review the video, Analysis of Variance (ANOVA).
Review the following tutorials from the Green and Salkind text:
Lesson 25, “One-Way Analysis of Variance”
Lesson 26, “Two-Way Analysis of Variance”
Review the Assignment Exemplar provided in this week’s Learning Resources.
Submit a 5- to 6-page paperusing the Assignment Exemplar.
Your paper must include the following elements:
An APA Results section for the one-way ANOVA test. (See an example of an APA Results section in Lesson 25, “One-Way Analysis of Variance” of the Green and Salkind text on pages 136-137.)
The critical elements of your SPSS output, including:
A properly formatted research question
A properly formatted H10 (null) and H1a (alternate) hypothesis
A descriptive statistics narrative and properly formatted descriptive statistics table (see page 134 of the Green and Salkind text)
A properly formatted box plot (see page 136 of the Green and Salkind text)
A properly formatted inferential APA Results Section (see pages 135-136 of the Green and Salkind text).
An appendix including the SPSS output generated for descriptive and inferential statistics (see SPSS output on page 134 [one-way ANOVA] and page 135 [post hoc results] of the Green and Salkind text)
Finally, explain how you would extend the one-way ANOVA to a two-way ANOVA using the variables in the IT Security Dataset.
