Below are the questions for the exam with the choices of answers:
Question #1
A All these are true about the design
B Comparing a treatment group to a control group is a between subjects variable.
C A static comparison group design has a treatment group and comparison group, but no pretest.
D Comparing pretest scores to posttest scores is a within subjects variable.
E Interrupted time-series designs have multiple pretests and posttests
Question #2
A None of the choices are correct
B Regression-discontinuity design
C Nonequivalent comparison group design
D Pretest posttest nonequivalent group design
E Pretest posttest control group design
Question #3
A Two groups got nutrition education, but 2 groups did not
B BMI was used at both pretest and posttest; however only 2 groups got the BMI pretest.
C This design is the Solomon 4-group design
D This design helps determine whether the pretest is influencing the posttest
E All these are true about the design
Question #4
A There is no pretest and only one group in a one-shot case study design
B All these are true about the design
C No pre-experimental designs will use random assignment; thus, there is no true control group. Also, there might not be a pretest in some pre-experimental designs.
D All quasi-experimental designs have pretest(s) and posttest(s), along with a treatment group, but there is no true control group because of the lack of random assignment.
E All true experimental designs have random assignment into groups (i.e., experimental and true control groups), pretest(s), and posttest(s).
Question #5
A This is a type of quasi-experimental design.
B All of these are true.
C Both groups get a pretest (01) and posttest (02)
D Subjects are randomly assigned into groups.
E There are two groups – one group gets treatment 1, one group gets treatment 2.
Question #6
A This is a type of quasi-experimental design
B This is not a true experimental design because there was no random assignment and no true control group.
C A cut-off score was used to assign participants into groups.
D All these are true about the design
E The design was a regression-discontinuity design
Question #7
A Solomon 4-group design
B One group pretest posttest design
C Regression-discontinuity design
D Pretest posttest nonequivalent group design
E Pretest posttest control group design
Question #8
A There was no pretest
B The design is pre-experimental
C Both groups got a posttest
D The design is a static group comparison design
E There was one treatment group and one comparison group
F All these are true about the design
Question #9
A Only two groups received a pretest, but all groups received a posttest
B Only 2 groups received treatment, and 2 groups did not receive treatment
C All these are true about the design
D Since two groups did not get a pretest, it was not a true experimental design
E Subjects were randomly assigned into the groups
