WebScatterplots can help you find multiple types of outliers. Some outliers have extreme values. These outliers are distanced from other data points, as shown below. Unusual observations have values that are not necessarily extreme, but they do not fit the observed relationship. WebA scatterplot can also be called a scattergram or a scatter diagram. In a scatterplot, a dot represents a single data point. With several data points graphed, a visual distribution of the data can be seen. ...
