Communication Research Practice Questions
For each of the following questions, select the best answer
from the given alternative choices. Additional instructions are given as
necessary. Read each question and all alternatives carefully before
selecting an answer.
Logic of Quantitative Research
1.1 How are "everyday ways of knowing" (like intuition, tradition, and
authority) different from scholarly ways of knowing (research)?
c. Research examines its assumptions; everyday ways of knowing do not.
1.2 The goal of behavioral (quantitative) approaches to communication research
is best described as which of the following?
a. Explaining, predicting, and controlling communication behavior.
1.3 Which of the following statements is the most accurate description
of the hypothetico-deductive research method?
d. The researcher develops a formal theory from which a specific hypothesis
is formulated and tested by observation and measurement, leading to generalizations
which are then used to refine the formal theory.
1.4 Assume that a researcher observes a relationship between sunspot activity
and stock market prices; specifically, when sunspot activity is high, stock
market prices fall; when it is low, stock prices rise. Can the researcher
assert that sunspot activity influences stock prices based on this observation
alone?
b. No; other explanations have not been ruled out.
Definitions

Simple Scenario: Theory Building
Read the following paragraph and answer the next three questions
A researcher suspects that television sets emit energy that damages
people's vision. To test her theory, she observes a sample of children
(none of whom wear glasses) and measures how far away they sit from the
television when they watch. Two years later, she observes the children
again, this time seeing how many are wearing glasses. Her data suggest
that young children who sit close to the television set are more often
diagnosed as needing glasses than children who sit further away, and announces
that her theory is supported.
3.1 In this situation, "distance from the television while watching"
is what kind of variable?
3.2 What kind of variable is "whether or not a child wears glasses"?
3.3 Suppose a critic disagrees with the researcher, saying that it is possible
that previously existing eye problems in the children may result in both
sitting close to the TV and in needing glasses. "Previous existence of
eye problems" is, in this case, an example of what kind of variable?
3.4 Which of the following is a characteristic of a "good" hypothesis?
3.5 What assertion about the variables being studied does the "null hypothesis"
make?
c. That there is no relationship between them.

Scenario: Threats to Validity
Read the following scenario and answer the next four questions.
An education researcher is interested in the effectiveness of a new
method of teaching reading to 1st graders. She divides the students into
two groups and gives each of them a reading test. She trains several teachers
in how to teach reading using the new method. Over the course of the school
year, one group is taught using the new method; the other group is taught
using the old method. At the end of the school year, she tests both groups
again and compares their scores to see if the new method is more effective
than the old.
10.1 Suppose the researcher divided the 1st graders into groups based
on their scores on the first test, with high scorers placed in the "old
method" group and low scorers placed in the "new method" group. What threat
to internal validity might occur?
c. statistical regression
10.2 Suppose that, on the day of the second test, several students are
absent because their parents are told that the test is "optional". What
threat to internal validity might occur?
10.3 Suppose that the researcher regularly visits the "new method" classrooms
in order to observe the teachers and the children. What threat to internal
validity might occur?
10.4 Suppose that the "new method" is supposed to be used by three of the
school's first grade teachers, but that one of those teachers decides to
incorporate different methods that he thinks will work better. What threat
to internal validity might occur?
d. treatment validity (means instrumentation)
Scenario: Experimental Designs
Read the following paragraph and answer the next three questions.
A researcher decides to investigate the relationship between public
speaking experience and self-confidence. She obtains subjects from a pool
of volunteers and randomly assigns them to one of two conditions.
In the first condition, subjects receive a one-week public speaking
course consisting of two hours each day practicing various types of speeches,
receiving critiques, and evaluating each other's work. In the second condition,
subjects do not attend this class.
All subjects fill out a questionnaire at the end of the week. The
questionnaire includes three items measured on a 7-point Likert-type scale
which asks subjects about their confidence in their own abilities to meet
challenges, overcome obstacles, and solve problems which they may encounter.
These items are then added together to create a "self-confidence scale".
11.1 What kind of design has the researcher used?
b. posttest only control group design
11.2 Which of the following is the treatment group?
a. The group that received the public speaking class
11.3 The fact that the subjects were volunteers can be used to support
which of the following statements?
a. The experiment has external validity (or generalizability) flaws
