I have a range of output data X (i.e. 1 column of values) that has repetitive values in it, I am trying to graph them using normal distribution but I am not getting a tidy bell curve... it is either lop-sided or is too rounded (doesn't look like a bell)
Do I need to reformat the data so that I have discrete values and frequencies instead? My maths is very poor, I have managed to graph some sample data from a website but each value only occurs once...
Any help would be greatly appreciated.
