Write My Thesis- Independent Samples t-Test:

Imagine a researcher is interested in the relationships among teachers’ self-esteem and productivity. A randomly selected sample of 40 teachers completed a questionnaire including a number of demographic questions as well as measures to assess their self-esteem and productivity. In the EDR-8201 Week 4 Worksheet you will find a table. This table provides the demographic data and participants’ responses for the self-esteem measure (100-point scale) and the productivity measure (50-point scale). Use these data to answer the questions below (these data have already been entered in a SPSS file; see the note below the data table).

Download the SPSS data set: “teachersurvey.sav.” Not all of the variables in that SPSS file will be used for this assignment.

In this SPSS assignment, use the tools learned in this course thus far to complete the following:

There are three main assumptions needing to be satisfied before using the independent-samples t-test for testing differences between the genders. Use SPSS to generate the output needed to test the assumptions. Please discuss each one and explain whether each has been met using SPSS output as needed to include the Shapiro-Wilk test for normality (used when the sample size is less than 50), histograms, and the Levene’s test. Keep in mind if the population value is unknown, it is permissible to infer from sample values. Regardless of sample size, test whether these assumptions are met.

Please produce an SPSS output for an independent-samples t-test comparing male and female scores on self-esteem.

What are the null and alternative hypotheses?

Report the results in APA format.

What might be concluded from this hypothetical study (males vs. female self-esteem test)? In the conclusions, please consider possible limitations of the study as well as recommendations for future research.
