2. Identify a concept (e.g., attitudes toward the
elderly, marital satisfaction, delinquency,
social class) that receives attention in this
area and that interests you.
3. Describe how you might conceptualize this
concept.
4. Describe one or more measurement strategies
you might use to operationalize this concept.
List at least one or more indicators and two
or more categories.
5. Identify the level of measurement of this
concept given the operationalization you
suggested. Give support for your answer.
6. Discuss the reliability of your measurement
strategy. How might you check the reliability
of this strategy?
7. Discuss the validity of your measurement
strategy. How might you check the validity
of this strategy?
PART B
EXERCISE 5 . 1
Practice Sampling Problems
This exercise gives you an opportunity to practice
some of the sampling techniques described in the
chapter.
The following is a list of the states in the
United States (abbreviated) and their populations
in 2005 to the nearest tenth of a million.
State Population State Population
AL 4.5 CO 4.5
AK 0.6 CT 3.5
AZ 5.5 DE 0.8
AR 2.7 FL 17.0
CA 35.5 GA 8.6
1. Number the states from 01 to 50, entering
the numbers next to the abbreviated name
on the list.
2. Use the random number table in Appendix E
and select enough two-digit numbers to provide
a sample of 12 states.Write all the numbers
and cross out the ones you don
’t use.
3. List the 12 states that make it into your
random sample.
4. Now, if you have easy access to the Internet,
locate the
Research Randomizer (http://
randomizer.org/) and draw one set of
12 numbers from 01 to 50 from it. Then list
the 12 states that would make it into your
random sample this time.
5. This time, take a stratified random sample of
10 states, one of which has a population of
10 million or more and nine of which have
populations of less than 10 million. List the
states you chose.
6. How might you draw a quota sample of
10 states, one of which has a population
of 10 million or more and nine of which
have populations of less than 10 million?
a. Describe one way of doing this.
b. Describe, in your own words, the most important
differences between the sampling
procedures used in Questions 5 and 6a.
