ESTIMATION

</ul style=”list-style-type:none”>

Estimation is the process of using a score from a sample of the population in order to estimate the score of the population. There are three different methods that can be used:

  • Point Estimation
      • The value of a sample statistic is used as a best guess or quick estimate of the population parameter

    • Interval Estimation
        • The use of sample statistics to determine a potential range of a population parameter. This interval is typically stated without stating any degree of confidence.

      • Confidence Interval Estimation
          • The use of sample statistics to determine a potential range of a population parameter. This confidence interval is stated with a degree of certainty or confidence.
