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.
An outlier is a piece of data that is much greater or less than most of the other data points. For example, in this data set... 5,7,6,7,5,7,7,22,5,6,5 ...the 22 is the outlier.The more or less one number in a set is, the more it affects the mean.n outlier is a piece of data that is much greater or less than most of the other data points. For example, in this data set... 5,7,6,7,5,7,7,22,5,6,5 ...the 22 is the outlier.
