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.
Outliers And Influential Points. An outlier is a data point that diverges from an overall pattern in a sample. An outlier has a large residual (the distance between the predicted value () and the observed value (y)). Outliers lower the significance of the fit of a statistical model because they do not coincide with the model's prediction.
The mean and mode are highly sensitive to outliers. What this means is that the presence of an outlier will dramatically affect both of these measures of the center. One advantage of the median is that it is not influenced as much by an outlier. To see this, consider the data set 3, 4, 5, 5, 6.
