Question
There are two independent variables:
Medication, which has two levels: “drug” or “placebo.” (“Drug” refers to the anti-cancer medication; “placebo” refers to an inert substance.)
Type, which refers to the type of pancreatic cancer, and has two levels: “endocrine” and “exocrine.”
Half the participants are given the drug, half the placebo.
Within each of these groups, half the participants have endocrine pancreatic cancer, and half have exocrine.
43. As described, this design is
a. 2x2 within-subjects
b. 2x2 between-subjects
c. 2x2 mixed design
d. correlational research
44. Consider a variation on the design described above. One group of patients has endocrine pancreatic cancer, another group has exocrine. In each of these groups, all the patients receive the drug during one phase of the study, and receive the placebo during another phase. This new design is
a. 2x2 within-subjects
b. 2x2 between-subjects
c. 2x2 mixed design
46. The appropriate statistical test for the design as originally described is
a. a one-sample t test
b. an independent samples t test
c. a paired-samples t test
d. an ANOVA
Explanation / Answer
43 ) Here, the 2 x 2 between subjects design will be perfect design for this experiment as there are tests two different level for two different categories.
so option c 2x2 mixed design
44 ) a. 2x2 within-subjects
45) option c a paired samples test
