![]() ![]() ![]() Replication (repetition of the complete design) is not common practice unless you need to assess the impact of some uncontrolled factor and/or to confirm the outcome of your analysis (among other less common reasons). ![]() These are the 2 reasons for the repetition of one experiment. This is done by comparing how well the model predicts the average of the repeated center points. Correspondingly, a type curve method is proposed to calculate the hydraulic parameters of the clay layer through laboratory experiment, which verifies the reliability of the analytical solutions. Additionally, these repetitions will allow (in certain designs) the assessment of the suitability/validity of the fitted model (opposite to lack-of-fit). However you don’t need to perform those repetitions if you have already a prior and reliable estimate of the variability. 1 inaccurate wording which changed the sense of what was said, 2 accurately described sense of what was said, but not exact wording, 3 accurately described wording The students who participate in the experiment might be interested to see the recording after they have completed their surveys. These repetitions allows the estimation of the experimental variability and as such to make inferences about the significance of the effect of the factors under study by comparing them to the experimental variability (noise). ![]() Quite often a center point (in triplicate or more) is repeated. As a rule of thumb, designs include the repetition (replicate and repetition meaning depend on the scientific field and context) of, at least, one experimental combination. ![]()
