Which of the following statements about the margin of error is false?
A) Statisticians routinely construct interval estimates by making their point estimate the interval center and creating a range of other possible values, known as the margin of error, below and above the center.
B) The margin of error is a half-width of an interval estimate, equal to the difference between the point estimate on the one hand and either the lower or upper limit of the interval on the other hand.
C) The unknown parameter is presumed to lie at the center of the interval that point estimate and margin of error create.
D) The margin of error only takes sampling error into account, ignoring all other potential sources of error, such as bias in questions, selection bias, or miscalculations.
E) None of these.
Margin of Error
An expression of the amount of random sampling error in a survey's results, indicating a confidence range within which the true value lies.
Sampling Error
The difference between a sample statistic and the corresponding population parameter, arising due to the fact that the sample is not a perfect representation of the population.
