100%.
Reliable correct answers If an experiment can be replicated.
Parsimony (Occaim's Razor) correct answers The finding should be explained and interprited in
the simplest and most economic way
Experiment correct answers The most common type of research. The researcher has control over
all relevant variables. Usually conducted in Labs or high control settings.
Confounding correct answers When undesirable variable enter the experiment.
Independent variable (IV) correct answers The variable that the experimenter manipulates
Dependent variable (DV) correct answers The result, the data, the scores, some form of human
response.
Control Group correct answers Group of people who don't receive any form of the IV or
experimental variable
Experimental Group correct answers Group of people who do receive the IV or experimental
variable.
Random Sampling correct answers 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 correct answers Subjects are randomly assigned to the experimental and
control groups.
, True Experiment correct answers Every member has an equal chance of selection AND are
randomly assigned to groups. Rare in most studies.
Quasi Experiment correct answers Any research that fails to use random assignment or lacks a
control group. All intact group studies.
Stratified Sampling correct answers People are selected from sub-groups.
Proportional Stratified Sampling correct answers 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 correct answers 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 correct answers 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 correct answers Research shows the finding are
comparable.
Representativeness of the sample correct answers More important to the study than the procedure
used to select the population.
Probability samples correct answers Random sampling, Stratified sampling, Cluster sampling,
"n"th sampling.
Non-probability samples correct answers Subjects are not selected based on probability.
