Simple 95% confidence interval for a median
Hi!
I have a data set of 86 values that are non-normally distributed (counts).
The median value is 10. I want to get an estimate of the 95% confidence
interval for this median value.
I tried to use a one-sample Wiolcoxin test:
wilcox.test(Comps,mu=10,conf.int=TRUE)
and got the following output:
Wilcoxon signed rank test with continuity correction
data: Comps
V = 2111, p-value = 0.05846
alternative hypothesis: true location is not equal to 10
95 percent confidence interval:
10.00000 17.49993
sample estimates:...
