Red and yellow creates orange. Yellow and blue creates green. The secondary colors can be mixed further to create additional shades. Tertiary colors are the result of a primary and secondary color mixed together. For example, orange mixed with red creates red-orange.
An influential point is an outlier that greatly affects the slope of the regression line. One way to test the influence of an outlier is to compute the regression equation with and without the outlier. This type of analysis is illustrated below.
In statistics an outlier is a piece of data that is far from the rest; think of a graph with dots, where most dots are clustered together in the middle, but one dot, the outlier, is at the top. Think of an outlier as an outsider. An outlier refers to anything that strays from, or isnât part of, the norm. If you like to sleep in a tent in the backyard while your neighbors and family sleep in their beds, youâre probably an outlier. You may also be an outlier if you have to travel far to your job.
