    Answer:

    how accurate the statistic is when using it to estimate the parameter.

    Step-by-step explanation:

    The margin of error may be referred to as a range or interval around a calculated statistic. The margin of error usually employed when calculating the confidence interval, will give a certain range of value within the sample statistic. This is sample statistic and margin is used to estimate the parameter albeit a certain percentage or proportion within the sample statistic. This provides the accuracy level at which the statistic will estimate the parameter.

    Margin of Error :

    Margin of Error = Zcritical * σ/√n ; OR

    Margin of Error = Tcritical * s/√n

    Where ;

    σ = population standard deviation

    s = sample standard deviation
