Which statistics to use- HELP!!!
Posted 09 April 2009 - 08:38 PM
I have done some phenotypic cells counts, 15 fields with each sample and 3 phenotypic characteristics, I have each represented as a percentage of the total cell number.
What I want to check is whether there is a statistically significant change between the same phenotype when the cells are undifferentiated and then differentiated.
Please let it be an easy one! I only have access to excel at the moment. Something like a T-test?
a speedy reply would be great as I can add it to my talk for tomorrow.

There is also an online tool allows you to calculate Fisher exact probability http://faculty.vassa.../fisher2x3.html

Chi squared- yes! I know this one and I understand it, which is more important.
Seriously, I don't really understand most statistics, I have missed out on this in my previous education somehow.
