The assessment performed
this year was completed in conjunction with the college’s General Education
Assessment Committee. A request was made by the committee to assess the
college’s General Education “Outcome 1” which concerns methodology. The
department agreed to test our Introductory Psychology students with 10
common questions, listed below:
- An investigator
has found a negative correlation between the amount of vitamin C people
take and the number of colds they get. The investigator could safely
conclude from this finding that:
- The more
vitamin C taken is associated with getting fewer colds
- People who
get few colds are compelled to take vitamin C
- Taking
vitamin C causes people to get few colds
- The more
vitamin C taken is associated with getting more colds
- An explanation
using an integrated set of principles that organizes and predicts
observations is called a(n):
- experiment
- hypothesis
- theory
- survey
- In a study
involving the effects of drug use on dreams, the type and amount of drug
used would be the _______ variable and the effect on a person’s dreams
would be the _____ variable.
- dependent,
independent
-
independent, dependent
- empirical,
rational
- rational,
empirical
- A correlation
between self-esteem and annual income of -.75 would indicate that:
- higher
levels of annual income are associated with lower levels of
self-esteem
- lower levels
of self-esteem are associated with lower levels of annual income
- higher
levels of self-esteem are associated with higher levels of annual
income
- it is
impossible to predict annual income levels from knowledge of
self-esteem levels
- The key
advantage of the experimental method is that it
- allows
for direct cause-effect conclusions
- enables
experimenters to study more phenomena
- is best
suited for the investigation of abnormal behavior
- enables
replication or empiricism
- The part of an
experiment that the experimenter deliberately manipulates is the:
- hypothesis
- control
group
- dependent
variables
-
independent variable
- A group of
researchers wanted to determine if people will eat more food in a room
with red paint and red decorations than in a room that is decorated in
blue. Half the participants in this study ate in a red room and half
ate in a blue room. The researchers then measured how much food was
consumed in each of the two rooms. In this study, the independent
variable was
- the type of
food that was available during the study
- the amount
of food that was consumed
- the color
of the decorations in the room
- how hungry
the participants were at the end of the study
- Which of the
following correlation coefficients expresses the strongest degree of
relationship between two variables?
- -.88
- .81
- .15
- 1.12
- What is a
representative sample?
- a small
population
- a group of
participants who know each other
- a sample
that is identical in size and characteristics to a population
- a sample
selected to reflect the characteristics of a population of interest
- Which of the
following is the best description of the use of inferential statistics?
- procedure
used to explain the relationship between two variables
- a method for
summarizing a large amount of data with a few numbers
- method used
to determine the practical importance of research findings
- procedure
for determining if differences are due to chance or non-chance
factors
The questions were
voted on by the department members to reflect the kinds of questions about
methodology that students in Introductory Psychology should know. Among the
546 Introductory Psychology students, the average score was 59% which, while
low, was significantly above chance,
t(356)
= 33.30, p
< .001. Notably, the Introductory Psychology students perform better than a
group of 149 History 1700 (US History) students (M
= 38.26%), t(674)
= 9.32, p
< .001).
Even among the History students, those had never had a psychology course (N
= 79) scored lower (M
= 34.80%) than those who had (N
= 70, M
= 46.89%), p
< .001.
The data were
interpreted as evidence that Introductory Psychology students do learn the
methodology of the discipline, but that more lower-division instruction in
methodology may be required. In response, the department developed a new
course, titled
Psychology as a Science
and Profession,
which will function to
offer lower division instruction in methods. The course was approved by the
Senate in May.
