Inferential Statistics

For instance, we use inferential statistics to try to infer from the sample data what the population might think. Or, we use inferential statistics to make judgments of the probability that an observed difference between groups is a dependable one or one that might have happened by chance in this study. Thus, we use inferential statistics to make inferences from our data to more general conditions; we use descriptive statistics simply to describe what's going on in our data. Here, I concentrate on inferential statistics that are useful in experimental and quasi-experimental research design or in program outcome evaluation.

Most of the major inferential statistics come from a general family of statistical models known as the General Linear Model. One of the keys to understanding how groups are compared is embodied in the notion of the "dummy" variable. PHAC SUR2: Communicating Data Effectively.

Descriptive Statistics. « PreviousHomeNext » Descriptive statistics are used to describe the basic features of the data in a study.

Descriptive Statistics

They provide simple summaries about the sample and the measures. Together with simple graphics analysis, they form the basis of virtually every quantitative analysis of data. Descriptive statistics are typically distinguished from inferential statistics. With descriptive statistics you are simply describing what is or what the data shows. Descriptive Statistics are used to present quantitative descriptions in a manageable form. Every time you try to describe a large set of observations with a single indicator you run the risk of distorting the original data or losing important detail. Univariate analysis involves the examination across cases of one variable at a time.
