CHAPTER ONE ASSIGNMENT, PART ONE
Answer format: all work is to be performed "by hand". Your submission must include all work required to reach
your answer. Credit will be assigned only to questions for which you have shown your work. Multiple-page
submissions MUST BE STAPLED!
Practice Problem items from text, beginning on page 25. You are required to complete only the
following items: 2, 7, 8, 11, 12, 14, and 18.

CHAPTER ONE ASSIGNMENT, PART TWO
Answer format: brief answers to most question parts are fine and even preferred. Just make sure your answer is
justified when requested. Copy and paste graphs/tables into a word file containing your answers (for instance,
next to number three, you should provide the table you were asked to create). Feel free to resize when it seems
appropriate. But make sure that the important aspects are still readable on printout. Duplex printing is fine and
even preferred. The text section "Using SPSS" (pages 29-32) will serve as an important resource should you
become stuck at any point. Staple Part Two to Part One.
Using the "sample depression data" provided on blackboard under datasets:
1) What is the variable name for the variable in the row numbered “4” in “variable view”?
What is the variable label? What does each possible number value for this variable mean in
real-life terms?
2) Is this variable nominal, ordinal, interval, or ratio? Why?
3) Create a frequency table in SPSS for that variable.
4) Using SPSS, create a histogram for that variable.
5) Now create a histogram for that variable that lays a normal curve on top of it. Does this
graph make it easier to tell if the data are normally distributed than did the previous
histogram? Would you describe these data as (a) fairly normally distributed, or (b) are they
extremely non-normal? If non-normal, how (examples: heavy skew or kurtosis, bimodal, etc.)?
6) Create a histogram for that variable that uses grouped frequencies. Use intervals of size 2.
Would it be better to show this histogram or an ungrouped in this instance? Why?
7) Enter into SPSS the data from Practice Problem 13 in your text (page 27), and create a
histogram for that variable.
