Assignment:
Using the data set electric.sav, use SPSS to run a distribution analysis on diastolic blood pressure (DBP58), examining the following for individuals who have had no history of cardiovascular heart disease and individuals with a history of cardiovascular heart disease (CHD). The variable that looks at individual history is CHD.
• Compute the following for each group:
o Mean
o Median
o Quartiles
o Range
o Variance
o Standard deviation
o Skewness
o Kurtosis
o o Under Plots, run a histogram, and show the normal curve on the histogram and run Stem-and-Leaf. (You will receive Box-and-Whiskers when running this analysis.)
o Submit your outputs from all SPSS runs, and briefly describe your results by answering the following questions:
o What can you determine from the measures of skewness and kurtosis relative to a normal curve? What are the mean and median?
o Does one seem better than the other to represent the scores?
o What differences can you see in the pattern of responses those with history versus those with no history?
o What information can you determine from the box plots?
