Requirements
The T-test Assignment will be graded on accurately completing a t-test using a specified data source. In addition to this, you are expected to analyze the results of the data, correctly report this information, and speak of the significance of findings in terms of public health. The quality of self-assessment, use of citations, use of Standard English grammar, sentence structure, and overall organization based on the required components as summarized in the directions and grading criteria/rubric will be evaluated.
Create your product using Microsoft Word, which is the required format for this assignment. Place output from SPSS into this word document as an appendix.
The length of this assignment is to be no less than 3 and no greater than 6 pages, excluding title and reference pages.
APA format is required with both a title page and reference page (no abstract is required). Use the required components of the review as Level 1 headers (upper and lower case, centered)
Introduction
This should introduce basic concepts of T-test and the use of it in statistics. It should also consist of the purpose of the paper.
Narrative
A narrative is a place for you to discuss the methods used and why this test is the appropriate test for the variables. You should also include a description of the variables, a description of the data set, and any other important information that will help frame your test findings in APA format.
Results
You will report the results you get, possible hypotheses, and if you have a statistically significant result. State whether you accepted or rejected your hypotheses.
SPPS Print out
Please provide the SPSS printout from the test you completed as an appendix to the paper. This should include everything from the printout page after the test is completed.
T-tests are used when the test statistic follows a normal distribution.  It can be used to determine if the means of two sets of data are significantly different from each other.
You will complete a paired T-test analysis for this assignment using the data set provided to you.
Module 2 Dataset (Links to an external site.)
A study tested whether cholesterol was reduced after using a certain brand of margarine as part of a low fat, low cholesterol diet. The subjects consumed on average 2.31g of the active ingredient, stanol ester, a day. This data set contains information on 18 people using margarine to reduce cholesterol over three-time points. There are two populations, A and B.
You will compare population A before margarine use vs. population A after 4 weeks of margarine use; compare population A before margarine use vs. population A after 8 weeks of margarine use.
The variables you will consider are cholesterol levels and the use of margarine.
You will include a narrative that includes possible hypotheses and null hypotheses, an explanation of the relationship between the variables, and report the important results in APA format.
