The Youth Risk Behavior Survey (YRBSS) is a national survey monitoring health behavior among youth and young adults. It is administered by the Centers for Disease Control and Prevention (CDC). For this use, the “Youth Risk Behavior Surveillance System Dataset” is provided to practice calculating and interpreting the t-test. Refer to the instructional videos in the topic resources and the Using and Interpreting Statistics: A Practical Text for the Behavioral, Social, and Health Sciences textbook as a guide.

Refer to the topic resources to review the documentation, questionnaires, and general information pertaining to the YRBSS and YRBS. Then use the 2015 “Youth Risk Behavior Surveillance System Dataset” and conduct a two-sample t-test to determine if weight (in kg) differs by sex. Submit the SPSS output for the t-test.
Create an 8-10 slide PowerPoint presentation to discuss the findings for the t-test. For the presentation of your PowerPoint, create lecture notes to further explain the slides displayed of the results and findings. Include an additional slide for references at the end.
Include the following:
- Identify which of three t-tests was selected and explain why this is the best statistical test and whether the assumptions were met.
- What are the null and alternative hypotheses?
- What is the decision rule?
- What is the test statistic and p-value?
- Interpretation of the t-test results (What was done? What was found? What does it mean? What suggestions are there for the creation of a health promotion intervention?)
side note (please read before accepting this question as a warning of how to get data file out into SPSS Software) —-> When you begin to upload “Youth Risk Behavior Surveillance System Dataset.xlsx” you can convert this file on your end of the computer into a “(.sav)” file into SPSS software of Citrix workspace. Studypool does not accept me dragging and dropping files of (.spv), so therefore I changed it on my end to an “XSLS” in order to provide the variables to apply for my t-Tests. When you open your blank SPSS software then you can click File, click Import Data, under Database will be the first option of Excel to open up your saved file of “Youth Risk Behavior Surveillance System Dataset.xlsx” to covert. You may need to make a separate folder under your username of the computer on either Mac or Windows to find the file easier when the “Open Data” box appears. Click on “Users”, click on “name of computer”, click on the folder you will make for this as “SPSS”, THEN it will be readily available to access. This is very helpful since I can send in (.sav) files.. I hope this helps!!
Submit the SPSS exported output and the PowerPoint.
