  3. 6.1 INTRODUCTION Inferential Statistics Inferential Statistics involves the use of statistic to form a conclusion, or inference, about the corresponding parameter.

  4. 6.2 Sampling Distributions Sampling Error The difference between population parameter and sample statistic used to estimate the parameter Sampling Distribution A all of possible values for a statistic and probability associate with each value.
