which margin of error to use - JamesResearch - Thu 9 May 2019

When trying to make a marketing claim do you use the margin of error based upon the sample size? Do you ever use the margin of error based upon a subsegment sample size.

Generally you want to use the most appropriate margin of error. If you're comparing or describing specific subsegments then you need to use the sample size for that segment.
