Experimental design quiz

A  Comparing a treatment group to a control group is a between subjects variable.

B  A static comparison group design has a treatment group and comparison group, but no pretest.

C  Comparing pretest scores to posttest scores is a within subjects variable.

D  Interrupted time-series designs have multiple pretests and posttests

E  All these are true about the design

A  Pretest posttest nonequivalent group design

B  None of the choices are correct

C  Nonequivalent comparison group design

D  Pretest posttest control group design

E  Regression-discontinuity design

A  This design is the Solomon 4-group design

B  This design helps determine whether the pretest is influencing the posttest

C  Two groups got nutrition education, but 2 groups did not

D  All these are true about the design

E  BMI was used at both pretest and posttest; however only 2 groups got the BMI pretest.

A  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.

B  All true experimental designs have random assignment into groups (i.e., experimental and true control groups), pretest(s), and posttest(s).

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  There is no pretest and only one group in a one-shot case study design

E  All these are true about the design

A  This is a type of quasi-experimental design.

B  All of these are true.

C  Subjects are randomly assigned into groups.

D  There are two groups – one group gets treatment 1, one group gets treatment 2.

E  Both groups get a pretest (01) and posttest (02)

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

A  Pretest posttest control group design

B  One group pretest posttest design

C  Solomon 4-group design

D  Regression-discontinuity design

E  Pretest posttest nonequivalent group design

A  The design is pre-experimental

B  There was no pretest

C  The design is a static group comparison design

D  There was one treatment group and one comparison group

E  All these are true about the design

F  Both groups got a posttest

A  Only two groups received a pretest, but all groups received a posttest

B  Since two groups did not get a pretest, it was not a true experimental design

C  Subjects were randomly assigned into the groups

D  Only 2 groups received treatment, and 2 groups did not receive treatment

E  All these are true about the design
