A4.4: Chapter 7, Problem 7.4, Cronbach’s Alpha to Assess Internal Consistency Reliability. For
each of the
following Scales; 7.4a Alpha for the Revised Competency Scale, 7.4b Alpha for the Revised Motivation
Scale, and 7.4c Alpha for the Revised Pleasure Scale, complete the following: Write a short narrative of
your process, an interpretation of your findings, and write your results. Cut and paste the Case
Processing Summary, Reliability Statistics, Item Statistics, Inter‐Item Correlation Matrix, and Item‐Total
Statistics tables directly into your document and refer to them in your interpretation. Include
appropriate headings to clearly show each separate reliability test completed. A4.5, Application Problem ‐ Measuring Reliability and Validity. Using the “hsbdata.sav” file, do the
following problems. Write a short narrative of your process, an interpretation of your findings, and your
results. Cut and paste your outputs directly into your document and refer to them in your
interpretation. Write the results. a. Write a research question and a null hypotheses relating to the variables “mosaic” and “mosaic2” that
could be answered using a paired sample t test. Run the t test and provide a full interpretation if the
findings to include the outputs. b. Combine “item01”, “item07”, “item12”, “item13” to form a summated scale. Run the Cronbach’s
alpha for that scale and provide a full interpretation of the findings to include the outputs.
