Hi everyone!
I don't know if this is where we are discussing stadistics doubts. But yesterday we have a small discussion in Aachen that I would like to share with you, and maybe our stadistics professional can help us.
When we plot a Graph with the data from our experiment...shall we use SD or SEM? The different is not really clear for me, I just see that SEM is always much smaller than SD, and therefore for sure looks nicer.
In my case, I always plot data from my experiments, and at the end what matters for me is the Mean between different groups, therefore people suggested that I should use SEM. Is it right?
Thank you!!
Hi, SD shows the spread of the data, while SEM shows the accuracy of the means as estimates of the population averages. So I think SD are more appropriate if the purpose of the graph is to show a concise summary of the raw data! I attach a paper that discusses this nicely.
best regards, Georg
Oh nice! Thank you Georg
You are welcome!
We are happy to discuss other problems and share literature if needed.
