Data sets definition in statistics a data set is a collection of data often placed in table form a data set is a collection of data, that contains one or more records of related information. At that time, statistics and probability theory took on a methodological role as an analysis of inductive inference, and attempts to ground the rationality of induction in the axioms of probability theory have continued throughout the 20 th century and in to the present. Statistical methods allow an estimate to be made of the probability of the observed degree of association between variables, and from this the statistical significance can be expressed, commonly in terms of the p value. Sensitivity analysis is a technique used to determine how different values of an independent variable will affect a particular dependent variable under a given set of assumptions.

An operational definition is the complete description of the processes that will take place when performing an investigation in easier terms, the steps that you are going to use to investigate. This joint probability, a multiplication of three separate probabilities, requires statistical independence of the three separate probabilities or events the interdependence of p and e in the lpe methodology: a caution to users about possible bias.
