The Hawthorne effect refers to finding that an outcome in this case, worker productivity changed due to observation itself. Inference can extend to forecastingprediction and estimation of unobserved values either in or associated with the population being studied; it can include extrapolation and interpolation of time series or spatial dataand can also include data mining.

Further examining the data set in secondary analyses, to suggest new hypotheses for future study.

The resulting partition function for that single-particle level therefore forms a geometric series: Design of experimentsusing blocking to reduce the influence of confounding variablesand randomized assignment of treatments to subjects to allow unbiased estimates of treatment effects and experimental error.

Nevertheless, because most clinical studies are of a modest size, it is usually advisable to transform non-normal data, especially when they have a skewed distribution.
