[R] Question in Chi-squared test, can I do it with percentage data?
Hi all,
I know Chi-squared test can be done with the frequency data by R function
"chisq.test()", but I am not sure if it can be applied to the
percentage
data ? The example of my data is as follow:
#############################################
KSL MHL MWS CLGC LYGC
independent (%) 96.22 92.18 68.54 93.80 85.74
#############################################
Thanks
Jeff

If these are counts, it makes a difference if these are 96 out of 100 or 960000 out of 1000000.
