Hi,

Could you show us dummy data that shows us what your data layout and values
are. As I read your question count rate is a single number and you can
calculate a mean and standard deviation of a singe number.

Please help!
I am trying to show a possible effect that a count rate has on whether a
specific test is succesful or not.
I have 2 sets of data both of which are measures of same parameter (i.e
count rate). I wish to display each set as either having passed or failed a
particular test. So I need a column of points that have passed and a column
that have failed (the count rate should be along the y-axis). I also wish to
display the mean and standard deviation of each passed count rate and failed
count rate.
