The weighted mean is similar to an arithmetic mean (the most common type of average), where instead of each of the data points contributing equally to the ... more
The standard error (SE) is the standard deviation of the sampling distribution of a statistic. The term may also be used to refer to an estimate of that ... more
The margin of error is a statistic expressing the amount of random sampling error in a survey’s results. The larger the margin of error, the less ... more
