To evaluate the coagulation effects of three drugs, 30 healthy volunteers were randomly assigned into 3 groups and injected with different drugs. Their relevant coagulation times were measured as follows A(group=1): 36.8 34.4 34.3 35.7 33.2 31.1 34.3 29.8 35.4 31.2 B(group=2): 40.0 35.5 36.7 39.3 40.1 36.8 33.4 38.3 38.4 39.8 C(group=3): 32.9 37.9 30.5 31.1 34.7 37.6 40.2 38.1 32.4 35.6 Questions: ① If you want to evaluate whether the coagulation effects of the three drugs are different, which method should be used? and what are the model assumptions for the application of this method? ② Compare the difference of the coagulation effects among three drugs by SPSS, present the main results and make interpretation. ③ Make pairwise comparisons of the efficacy of the three drugs, write out the method of pairwise comparison you adopted (just write one method) and the corresponding p-values.
To evaluate the coagulation effects of three drugs, 30 healthy volunteers were
randomly assigned into 3 groups and injected with different drugs. Their relevant
coagulation times were measured as follows
A(group=1): 36.8 34.4 34.3 35.7 33.2 31.1 34.3 29.8 35.4 31.2
B(group=2): 40.0 35.5 36.7 39.3 40.1 36.8 33.4 38.3 38.4 39.8
C(group=3): 32.9 37.9 30.5 31.1 34.7 37.6 40.2 38.1 32.4 35.6
Questions:
① If you want to evaluate whether the coagulation effects of the three drugs are
different, which method should be used? and what are the model assumptions
for the application of this method?
② Compare the difference of the coagulation effects among three drugs by SPSS,
present the main results and make interpretation.
③ Make pairwise comparisons of the efficacy of the three drugs, write out the
method of pairwise comparison you adopted (just write one method) and the
corresponding p-values.
