Question

What conclusion can be made from the SPSS output?

a. The null hypothesis that the mean LOS for the various MS-DRGs are equal should be rejected

b. The LOS for MS-DRG 291 is significantly longer than the other MS-DRGs

c. The null hypothesis that the mean LOS for the various MS-DRGs are equal should not be rejected

d. The test is inconclusive

What might be the next step in this analysis?

a. No next step, nothing is statistically significant

b. A regression to model length of stay 13

c. Tukey’s post hoc test to determine which MS-DRG means are different

d. Levene’s test to determine if the group variances are different

Explanation / Answer

NUll hypothesis:mean LOS for the various MS-DRGs are equal

Alternative Hypothesis:atleast one of the means are different.

alpha=0.05

From SPSS output

F=19.715

p=.000

p<0.05

Reject Null hypothesis

Accept alternative hypothesis

What conclusion can be made from the SPSS output?

a. The null hypothesis that the mean LOS for the various MS-DRGs are equal should be rejected

What might be the next step in this analysis?

c. Tukey’s post hoc test to determine which MS-DRG means are different
