Laboratory experiments and practical measurements serve several purposes, some of which do not demand accuracy. Some experiments are exploratory in the sense of looking for the existence and direction of some effect before trying to establish its magnitude; others are chiefly instructional, to ...
A significant amount of effort is put into the design of experiments, whether they are being conducted at a private research facility, a university lab, or a high school classroom. This effort is undertaken to avoid as many mistakes and errors as possible. Unfortunately, regardless of how well...
Instead of trying to fit your DOE campaign into a single experiment, think of the DOE process as a collection of sub-experiments. And for each sub-experiment, you might use a different design—as every type of DOE design at each step is intimately linked to a phase in the DOE campaign....
Type of researchWhat’s the difference?What to consider Primary research vs secondary researchPrimary data iscollected directly by the researcher(e.g., throughinterviewsorexperiments), while secondary datahas already been collected by someone else(e.g., in governmentsurveysor scientific publications)....
Factorial ANOVA is an efficient way of conducting a test. Instead of performing a series of experiments where you test one independent variable against one dependent variable, you can test all independent variables at the same time.VariabilityIn a one-way ANOVA, variability is due to the ...

Experiments are usually designed to find out whateffectone variable has on another – in our example, the effect of salt addition on plant growth. You manipulate theindependent variable(the one you think might be thecause) and then measure thedependent variable(the one you think might be theef...

The ability of the Elders to speak anywhere at any time, and of the Giver to pass on ancient memories to Jonas, reveals an advanced level of technology that is almost mystical in The Giver. The advancements in his experiments brought him to a point of no return, and Jekyll ultimately make...
Types of quasi-experimental designsMany types of quasi-experimental designs exist. Here we explain three of the most common types: nonequivalent groups design, regression discontinuity, and natural experiments.Nonequivalent groups designIn nonequivalent group design, the researcher chooses existing groups ...
