Determine the margin of error

WebFeb 26, 2010 · Margin of error – the plus or minus 3 percentage points in the above example – decreases as the sample size increases, but only to a point. A very small sample, such as 50 respondents, has about a 14 percent margin of error while a sample of 1,000 has a margin of error of 3 percent. WebMay 8, 2024 · To solve for sample standard deviation s, we use the mathematical definition for a margin of error for ˆμ, which is M E = zα/2 ⋅ s √n provided the sample size is large enough (usually at least 30 or 40). Solving this for s gives s = M E ⋅ √n zα/2 For a 95% C.I., we have α = 0.05, and zα/2 = 1.96 (from z -table lookup).
