Order for the Margin of error in the graph given above is?: (A) 3>2>1, (B) 3>1>2, (C) 1>3>2, (D) 1=2=3
Answer is A. (a) 3>2>1* Margin of Error: Amount of random sampling error in a survey's results* Margin of error is simply the "radius" (or half the width) of a confidence interval* Margin of error = Critical value x Standard error* Standard error is inversely related to sample size (SEmean = SD/[?]Sample size)* Margin of error is inversely related to the Sample size
