Question Description

Assignment is attached below in the file I uploaded. Part 3 you will be unable to do and I will do myself. I hav attached the the lecture notes for correlations, regression etc. .

Review the first part of these lectures describing statistical tests for which types of variables to analyze (you do not need to know yet how to run your variables in SPSS - that's in Weeks 4 and 5!).

For this class, you may be able to use an ordinal variable in place of a numeric (interval/ratio) variable when the ordinal variable makes numeric sense (for example: 1 = low, 10 = high).

Correlations Correlations (I would probably recommend regression over correlations for your MAIN method of analysis, but there may be times when correlations are appropriate)

Regression Regression

t-tests t-tests

ANOVA ANOVA

Chi Square/ Cross-tabs Cross-tabs

Your Research: Exploring Your Variables and Analysis GOAL: To correctly identify your variables for analysis and which statistical technique you will later use to test your hypothesis. You will also be required to demonstrate that you can access and open the SPSS file (you will need to be able to open SPSS for Written Exam 3) You may enter your responses to the questions below directly into this document and submit this completed document under the appropriate link in the course site. Instructions: Part I Choose one hypothesis you developed in your Written Exam 1. This will be the hypothesis you investigate and write about this semester (and in the questions below). Below, list your single outcome variable and your predictor variables (you must list at least 2) that will be part of your research (Step A). For each listed variable, indicate what type of variable it is (i.e. level of measurement - refer to Chapter 5 in your textbook to learn about levels of measurement) (Step B). A. My single outcome variable is (1)__________ and my predictor variables are (2)___________, (3)________________, and (4)_________________. B. List all the variables (outcome and predictors) with the corresponding level of measurement (i.e. gender – nominal). Be sure to distinguish between interval and ratio levels of measurement. 1. 2. 3. 4. Part II Review the statistical tests lectures (i.e. ANOVA, correlations, etc.) to investigate different analysis techniques. The statistical tests will depend on the level of measurement. If you’re unsure of the level of measurement for your variable, please review the Class Survey Codebook. Based on the type of variables in your hypothesis, indicate which technique (or techniques) you will use to investigate how your predictor variables relate to your outcome variable. - Note: Because you have multiple predictor variables, you may be able to use a single analysis technique that incorporates all of your predictors at once (ex. they can all fit in a multiple regression) OR you may need to run one or more separate analyses (with one or more different analysis techniques). Do your best to investigate your analysis options and explain (to the best of your ability) how you plan to analyze your data. (Example, I will use [statistical test] to see if [variable 1] and [variable 2] predict [outcome variable – variable 3]. I am using this [statistical test] because [variable 1] is a [level of measurement] variable, [variable 2] is a [level of measurement] variable, and [outcome variable variable 3] is a [level of measurement] variable. Part III You will be required to use SPSS for Written Exam 3. These are essentially 3 free points to encourage you to have SPSS downloaded, updated, and ready to go for you to run analyses in Week 5. Follow the following steps then provide a screenshot of the opened dataset with a date and time stamp: 1. Go to Week 5 2. Click on “Instructions and Resources: Written Exam 3 Methods and Results” 3. Follow the instructions under Step 1 4. Open the dataset provided in Step 4 5. Take a screenshot of the opened data file and paste the screenshot below Class Survey Codebook • • Variable name for a given question in SPSS highlighted in yellow. In other words, when you are in SPSS looking for your variable, you will look for the variable name that is highlighted in yellow Coding for each variable listed as # next to variable response options. o For example, if someone responded they were male, it was entered as a “0” in SPSS.
