At Day0 I obtain a population of

flies, and dissect some of these flies at each time-point (I.e. I have a population of 30 flies at Day0. I dissect 3 of them right away, 3 more after 1 day, another 3 after 3 days, and so on up to 15 days after birth). To obtain these results I need to dissect (thus killing) the fly, so I cannot assay the differences in a single individual fly changing overtime, but I can assay the differences in the whole population. What I obtain is a n number of around 50 for each timepoint. I could just plot the average for each timepoint on a chart and show the variation overtime this way. I would use standard error of the mean to build up the error bars. My problem is that I need to show these data not as raw data, but as a ratio over the first Day, in order to better show the decrease in the cell number overtime. To do this, I am showing my data as a percentage ratio over day0 [(Day1Mean/Day0Mean)*100]. To make it more clear: Day0 mean: 5 Day1 mean: 4 Day3 mean: 3.5 Day6 mean:

As for the specific values of the error itself, that's really up to what measurement of error is appropriate for your situation.http://www.mathworks.com/help/matlab/ref/errorbar.html 0 Comments Show all comments Log In to answer or comment on this question.
