Statistical hypothesis testing is a key technique of both frequentist inference and bayesian inference, although the two types of inference have notable differences statistical hypothesis tests define a procedure that controls (fixes) the probability of incorrectly deciding that a default position ( null hypothesis ) is incorrect. Confounding variables are a specific type of extraneous variable extraneous variables are defined as any variable other than the independent and dependent variable. In experimental and observational design and data analysis, the term control variable refers to variables that are not of primary interest (ie, neither the exposure nor the outcome of interest) and thus constitute an extraneous or third factor whose influence is to be controlled or eliminated the term refers to the investigator's desire to estimate an effect (such as a measure of.

Generally, one or more variables are manipulated to determine their effect on a dependent variable the experimental method is a systematic and scientific approach to research in which the researcher manipulates one or more variables, and controls and measures any change in other variables. Correlation (pearson, kendall, spearman) correlation is a bivariate analysis that measures the strength of association between two variables and the direction of the relationship in terms of the strength of relationship, the value of the correlation coefficient varies between +1 and -1.
