Assignment Requirements

Use the scale you have developed in Unit 5 and give it to at least five people (more if possible). For the purpose of this assessment, you will replicate the responses so that you have a minimum of 50 responses. Say, for example, that you have collected data from five individuals and coded it in your Excel spreadsheet. Copy and paste that data (5 rows) 10 times so that you have 50 rows of data. This is what you will enter into SPSS. Note: we are doing this so that we have a minimal number of respondents to obtain a useful measure of reliability. Remember, you would never do this for any real research study. Report on the results of your reliability analysis as part of this assignment by providing your Cronbach alpha.

To successfully complete this assessment, you must:

Interpret the descriptive statistics for the data set of 50 rows from the field test.

Paste your SPSS tables into your paper; don’t attempt to “redraw” them:
