TERMS TO KNOW
  • Margin of Error

    An amount by which we believe our sample's mean may deviate from the true mean of the population.

  • Estimate

    The mean value obtained from the sample. If the sample was well-collected, the estimate should be reasonably close to the true value.

  • Confidence Interval

    A range of potential values that the true value could be. It is obtained by adding and subtracting the margin of error from the value in the sample.
