You could try making two curves on the same graph (so that the two can be compared). I tried opening the attachment but it failed, I don't know why.
Not 100% if this belongs in here! Its not really university level statistics or pre-university statistics as its not really stastistical theory. Its more applied statistics really!
Following a basic university biomedical lab experiment, I was given this data (in attachment) and was then instructed to do the following:
"Provide a graph comparing breath alcohol levels with reaction times for your subject and control, labelled and annotated appropriately. [8 marks]"
I've been thinking about this for a very long time and I'm not entirely sure in what format to represent this data!
I could do the 'breath alcohol levels' vs. 'reaction times; quite easily if the control group wasn't involved. I'm just not sure how to involve the control group at all because their breath alcohol level is always pretty much 0 and so it doesn't fit in with the variability of the subject group's breath alcohol level...
P.S. I used to come here years back for my A Levels when I was planning to do Math at uni. Then I made a drastic change into Biomedical Sciences...don't ask why!
