Document Summary

Independent data points- when the value of a variable does not infer what the value of another variable is. Random variation- re moving and controlling factors one is no interested in to get a variation in the variables one is interested in. Confounding factor- the study of the effect of v a on v b, but variable also effects c which makes c the confounding factor. Hypothesis- clearly stated description of how a experimental system works. Indirect measure- taking on variable we are not interested in to get a variable that we are interested in. Control- reference against which the results of an manipulated experiment can be compared. Concurrent control- running a control group at the same time as running a manipulated group. Historical control- using historical data as a reference.
