Statistical conclusion validity
Does a relationship exist between the two variables? Statistical conclusion validity pertains to the relationship being tested. Statistical conclusion validity refers to inferences about whether it is reasonable to presume covariation given a specified alpha level and the obtained variances (Cook & Campbell, 1979). There are some major threats to statistical conclusion validity such as low statistical power, violation of assumptions, reliability of measures, reliability of treatment, random irrelevancies in the experimental setting, and random heterogeneity of respondents.
