| Feb 5, 2019 at 11:20 | comment | added | wnawaz | Thank you for your prompt response and I completely agree with what you have said. However, you have mentioned about two distributions, which give me an impression that we are comparing two samples (regardless - dependent or independent), whereas my original question is about one sample. I have a fixed median value (test score) which I want to compare with all statements (data points) to see if the median is statistically higher (than the fixed median). In such a case, how do I find the pairwise difference? If I treat the fixed value as a pair against each data point, its still skewed. | |
