CPCE QUESTIONS AND
CORRECT ANSWERS
GRADED A+ 2025-2026
Reliable - ANS-If an experiment can be replicated.
Parsimony (Occaim's Razor) - ANS-The finding should be explained and interprited in
the simplest and most economic way
Experiment - ANS-The most common type of research. The researcher has control over
all relevant variables. Usually conducted in Labs or high control settings.
Confounding - ANS-When undesirable variable enter the experiment.
Independent variable (IV) - ANS-The variable that the experimenter manipulates
Dependent variable (DV) - ANS-The result, the data, the scores, some form of human
response.
Control Group - ANS-Group of people who don't receive any form of the IV or
experimental variable
, Experimental Group - ANS-Group of people who do receive the IV or experimental
variable.
Random Sampling - ANS-Every member of the population has an equal probability of
being selected for the study and the selection of one member of the population has no
effect on the selection of an other member.
Random assignment - ANS-Subjects are randomly assigned to the experimental and
control groups.
True Experiment - ANS-Every member has an equal chance of selection AND are
randomly assigned to groups. Rare in most studies.
Quasi Experiment - ANS-Any research that fails to use random assignment or lacks a
control group. All intact group studies.
Stratified Sampling - ANS-People are selected from sub-groups.
Proportional Stratified Sampling - ANS-The data reflects the pattern that occurs
naturally. i.e. the population you are working with is 1/2 black and 1/2 white. Your
study would have 1/2 black 1/2 white
Cluster Sampling - ANS-A naturally existing group is selected. i.e. an experiment
wanted to show the side effect of a certain drug on substance abusers in treatment
users so the experimenter contacts substance abuse programs and selects people from
those.
"n"th Sampling - ANS-The experimenter picks every "10"th person or every "2"nd
person from a population and that is how your groups are generated.
Systematic sampling v. Random sampling - ANS-Research shows the finding are
comparable.
