I have ~700 patients. I used SPSS version 24. I first wanted to check if there is a correlation between the troponin level (numeric/continuous) and several other lab parameters for each patient - some are numeric/continuous and some are numeric/ordinal (e.g. white blod cell count, hospitalization days, etc..). as the troponin levels did not follow normal distribution, I used

**spearman's correlation**. I then wanted to check whether or not a certain individual is more likely to die if he had a higher troponin result. (so death was is a categorical variable with two levels, - YES/NO right?) . for that I used the

**Mann-Whitney test**, having the Troponin levels as the test variable and death as the grouping variable.

since i got weird results i wanted to make sure that i did the right tests...
