The Southwell plot is a graphical method of determining experimentally a structure's critical load, without needing to subject the structure to near-critical loads. [1] The technique can be used for nondestructive testing of any structural elements that may fail by buckling .
In the first example provided above, the sex of the patient would be a nuisance variable. For example, consider if the drug was a diet pill and the researchers wanted to test the effect of the diet pills on weight loss. The explanatory variable is the diet pill and the response variable is the amount of weight loss.
Line chart showing the population of the town of Pushkin, Saint Petersburg from 1800 to 2010, measured at various intervals. A line chart or line graph, also known as curve chart, [1] is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. [2]
The interaction plot may use either the air temperature or the species as the x axis. The second factor is represented by lines on the interaction plot. There is an interaction between the two factors (air temperature and species) in their effect on the response (body temperature), because the effect of the air temperature depends on the species.

If the factor levels are simply categories, the correspondence might be different; for example, it is natural to represent "control" and "experimental" conditions by coding "control" as 0 if using 0 and 1, and as 1 if using 1 and −1. [note 1] An example of the latter is given below. That example illustrates another use of the coding +1 and −1.
For example, typical fresh chili peppers have a water content around 90%, whereas Tabasco sauce has a water content of 95%. [12] For law-enforcement-grade pepper spray , values from 500,000 up to 5 million SHU have been reported, [ 1 ] [ 13 ] but the actual strength of the spray depends on the dilution. [ 3 ]
A funnel plot is a graph designed to check for the existence of publication bias; funnel plots are commonly used in systematic reviews and meta-analyses. In the absence of publication bias, it assumes that studies with high precision will be plotted near the average, and studies with low precision will be spread evenly on both sides of the ...
