Due Date: Nov 18, 2015 23:59:59       Max Points: 20

Details:

A correlation determines if there is any statistical relationship between variables. The Pearson product-moment correlation coefficient measures the relationship between two variables. In this assignment, you will review the SPSS output for a correlation and use it to answer questions about the groups. You will also review the SPSS output to determine if a correlation exists between the variables.

General Requirements:

Use the following information to ensure successful completion of the assignment:

Directions: 

Review the SPSS output file which reports the results of the correlation to see if there is a correlation between the cost of beer and the number of calories it contains or the cost of beer and the volume of alcohol it contains. Answer the following questions based on your observations of the SPSS output file:

Based on the correlation coefficients (r-values) that were computed and their statistical significance, what conclusions do you draw regarding

  1. The researcher’s question of correlation between the cost of beer and the number of calories it contains?
  2. The researcher’s question of correlation between the cost of beer and the volume of alcohol it contains?

SPSS Access Instructions

SPSS (Statistical Program for the Social Sciences) is a computer program that is the de-facto standard used by research institutions and universities for the completion of quantitative analysis.As a doctoral learner, knowledge of quantitative research techniques and the application of these methods as provided in the application software is a required doctoral competency.Doctoral learners are required to use SPSS during several courses to complete specific assignments.Doctoral learners may execute SPSS Base Module and Advanced Statistics in one of two ways.

SPSS Installation on Learner’s PC or MAC

SPSS Base and Advanced Statistics Modules may be installed on a PC or MAC computer.The combined program is very large so please make sure you have at least 2 GB of available disk space on your computer.Once the program file is downloaded, you may access SPSS software to complete classroom assignments and perform quantitative analysis as related to your own research.Actual installation can be performed in less than five minutes after the file has been downloaded.However, the initial download may exceed 60 minutesif your Internet connection is relatively slow.In some instances when the download exceeds 60 minutes, the download may not complete.Should you experience issues when attempting to download the SPSS file, please access the SPSS Server (below). Please use the following links to obtain installation instructions and the program file:

All SPSS programs installed on learner computers employ a security activation key which is in effect for 12 months. Should you receive a message indicating your SPSS software is out of date or requires a new activation key, simply follow the PC Update or MAC Update instructions. The update is typically completed in less than five minutes.

SPSS Server Access

The SPSS Server provides a convenient alternative method to access SPSS Base and Advanced Statistics Program via the Internet.Instead of downloading the entire SPSS program onto your computer (which can exceed 60 minutes), you may access the SPSS program via the Internet by downloading a small activation file (in less than five minutes).Once the activation file is downloaded, you may access SPSS software from any location where you are connected to the Internet to complete classroom assignments and perform quantitative analysis as related to yourown research.Please use the following link to obtain instructions on how access the SPSS Server.

Remember that when completing course assignments using the SPSS server, it is necessary to first download the SPSS data file (.SAV) prior to accessing the SPSS Server.Once the data file is download to your computer, you can OPEN the file directly from SPSS.

Technical Support

Should you encounter any technical issues when attempting to install SPSS on your computer or access the GCU SPSS Server, please contact GCU IT Technical Support at 877-428-8447.Hours of operation: Monday – Friday: 6 AM – Midnight; Saturday and Sunday: 7 AM – Midnight (AZ time). Should you require assistance using SPSS to perform analysis, please contact your GCU faculty member.
