The Critical Value. The critical value for our margin of error formula is denoted by zÎ±/2. This is the point z* on the standard normal distribution table of z-scores for which an area of Î±/2 lies above z*. Alternately is is the point on the bell curve for which an area of 1 - Î± lies between -z* and z*.
The margin of error is a statistic expressing the amount of random sampling error in a survey 's results. It asserts a likelihood (not a certainty) that the result from a sample is close to the number one would get if the whole population had been queried.he margin of error is a statistic expressing the amount of random sampling error in a survey 's results.
