Question

Midterm 2 A statistical analysis Version A oups. Table 3a and was conducted to compare standardized test scores between the study and 3b shows partial results. Table 3a N Mean Std Deviation Std Error Mean 12 920 10,492 Test Results Sig Sig. 2. Mean t d tailed) Difference Difference std Error 97.5% of the Equal variances 3.810 995 18.204 Equal variances not 3.027 13.213 .010 3.171 1.584 17.614 11. case as, which statistical analysis was performed? a) Fisher test Independent t-test br c) d) Mann-Whitney U test 12. Based on case a3, what alpha level is used in this analysis? a) 0,010 b) 0.013 0,025 d) 0050 13. Based on case ma, what p value should be reported to indicate whether or not there is a statistical a) 010 0013 c) 0,025 d) 0,060 14, Based on case M3, the BEST interpretation is that the scores in the study group are than those in the control group, s) significantly higher b) significantly lower neither higher nor lower

Explanation / Answer

14. p - value = 0.013 which is less than alpha so we reject Ho.

Hence,

Option b is correct.

16. Here we are comparing the same test score two time and hence, the samples are dependent.

Therefore,

Option c is correct.
