Document Summary
Don"t worry about true zero it is ratio. If it"s even number of cases you take the two and average them out. If there is an outlier you must use median as measure of central tendency. When we speak about the canadian public we speak based on our sample. The question is how close we get into our actual population. There is always room for standard error . N = number of cases = 1219. P = percentage of people who chose certain value= in terms of agree it is 32. 6 (1-p) = must equal 100 so = 1-33=67. If variance increases (numerator) then your se increases. If the number of cases (denominator) decreases your standard of error increases. The constant increase of cases retrieves diminishing decrease in standard error. Error to the mean statistics and subtract it this gives you.
