MTM Margin of Error

Margin of Error is a statistic expressing the amount of random sampling error in a survey’s results. For example, if a survey has a margin of error of ±2.5, 19 times out of 20, that means that if the same survey were conducted 20 times, 19 of those times would generate results with plus or minus 2.5% of the original finding. More specifically, if a survey found that 34% of Canadians ate cereal every morning, the margin of error would indicate that if that question was asked 20 times, 19 of those times would generate results with 31.5% and 36.5% (plus or minus 2.5 percentage points from 34).
