Cross Tabs. This week’s main Forum requires you to answer the question completely and correctly to receive full credit.
(Research Topic attached below)
This week we talk about the uses of a crosstabulation (crosstabs) and the benefits of creating this “snapshot” of your data.
For this forum, provide a brief introduction to your study to remind your classmates what we are reading about here. Include:
1. Your overall research question
2. The research hypothesis and null hypothesis
Next, create a crosstab for your data and include it in the post. Be sure to explain your findings, including a description of the data, a calculation of the epsilons, and a discussion of the10% rule. The epsilons in short are the differences between the highest and lowest column % in any given row. As long as one epsilon makes the 10% threshold, we’ll deem two variables have “enough” going on to with each other to warrant further statistical analysis.
When a variable is continuous (interval/ratio level of measurement), for example, age of respondent, we do not run crosstabs directly b/c it will result in a really spread-out table with lot of 0s and low frequency cells. Such a crosstab does not help us understand the data.
The correct way is to reduce the level of measurement to either ordinal level or nominal level (group the numbers into categories) and then run the cross table. You do this by recoding (See Week 3 Optional Forum). In this way, your crosstabs will help us better understand data. Here is another example of recoding in a video: https://www.youtube.com/watch?v=uzQ_522F2SM
Forum Instructions: Each forum week, learners will post one initial post and three peer responses. This post must demonstrate comprehension of the course materials and the ability to apply that knowledge in the real world. Learners will engage with the instructor and peers throughout the learning week. To motivate engaged discussion, posts are expected to be on time with regular interaction throughout the week. All posts should demonstrate college level writing skills. To promote vibrant discussion as we would in a face to face classroom, formatted citations and references are not required. Quotes should not be used at all, or if necessary, used sparingly. If you quote a source, quotation marks should be used and an APA formatted citation and reference provided.
Forum requirement is 300 words
