Webtestwise alpha level in hypothesis testing, the significance level (i.e., the level of risk of a Type I error) selected for each individual test within a larger experiment. This is in contrast to experiment-wise alpha level, which sets the total risk of Type I error for the experiment. WebCH. 12 Pilot testing before conducting an experiment helps to be sure that the independent variables will be interpreted as expected. CH. 12 A threat to internal validity that refers to the fact that the researcher knows the research hypothesis and thus causes an invalid confirmation of the research hypothesis is known as experimenter bias. screen sharesWebA physician conducted an experimental study to compare the effectiveness of four different weight-loss programs.
