I appreciate this greatly... I am working with people that don't understand even the basics (such as a survey with 49 responses means that the margin of error is over 10% and thus comparing 1 month's results of say '68 per cent' with next month's '75' is meaningless); hope that this will help me better explain what they are missing.
- 2b3a51 3y agoYour example includes just about every manager I have ever worked with in a 35 year teaching career. National exam pass rate of 67% does not imply that every class of 20 will have 14 or 15 passes! I really appreciate the author providing access to the LaTeX source as well.

So intuitively the bigger the population the bigger the bound for the margin of error.
- shrubble 3y agoSorry for not being clear, the population is about 900-1200 (customers who have opened tickets in the calendar month) and the survey count (responses) is (can be) 49.
- sokoloff 3y agoMy favorite is when a survey result is presented with “as many digits as my calculator showed”, often allowing me to derive how many responses were likely received.
