normalising values - histograms
I current have device delay values that I have plotted over time (so time on the x axis and the delay values on the y axis). This is for all the delay values that I was given for all devices.
I have been told that I should normalise these delay values per device....I'm a bit confused as to what that means though...Does normalise automatically imply a histogram? i.e. Must I get the mean, standard deviaition and plot as a histogram and is that then normalised?
Any help greatly appreciated - my stats knowledge is non existent really.
