my output is as follows:
wilcox.test(main_samp$SCORE~main_samp$GENDER, conf.int = TRUE)
Wilcoxon rank sum test with continuity correction
data: main_samp$SCORE by main_samp$GENDER
W = 2780.5, p-value = 0.04829
alternative hypothesis: true location shift is not equal to 0
95 percent confidence interval:
-6.800005e+01 -2.056837e-05
sample estimates:
difference in location
-33.00003
result of W seems suspicious since i expect the result to be between 0 and 1.
and the confidence intervals are also -ves what could be the challenge?
Thanks Taby
