PPT-Parametric Inferential Statistics

Types of Inference Estimation On the basis of information in a sample of scores we estimate the value of a population parameter Hypothesis Testing We determine how well the data in the sample fit with the hypothesis that in the population a parameter has a particular value. 1 (Version 1: 8/27/2014 ) SPSS for Inferential Statistics SPSS for Inferential Statistics 2 (Version 1: 8/27/2014 ) Background Information IBM SPSS Statistics is a software package used for statisti The University of Reading Statistical Services Centre 1.
