	Data Mining Survivor: Multiple_Variable - Multi-Dimension Scatterplot
		This produces a scatterplot for each pair of variables, with the variable names identified in the diagonal.
		Each plot is a scatterplot of the data for the variable in the column by the variable in the row.
		The upper right triangle of the scatterplot is the mirror image of the lower left triangle of the scatterplot--with the axes swapped.

	Definition: Scatterplot - TheMeasurementGroup.com (Site not responding. Last check: 2007-11-03)
		A scatterplot is a way of representing the scores of a group of clients in a graphic fashion.
		Scatterplots are a very useful way of showing the relationships of two variables, X and Y, for a group of individuals.
		Scatterplots should be examined to see if there appears to be a systematic relationship between X and Y variables such that high (or low) scores on the X variable are systematically associated with high (or low) scores on the Y variable.

		Frequency scatterplots display the frequencies of overlapping points between two variables in order to visually represent data point weight or other measurable characteristics of individual data points.
		Unlike the regular scatterplot in which one variable is represented by the horizontal axis and one by the vertical axis, the multiple scatterplot consists of multiple plots and represents multiple correlations: one variable (X) is represented by the horizontal axis, and several variables (Y's) are plotted against the vertical axis.
		The Multiple scatterplot is used to compare images of several correlations by overlaying them in a single graph that uses one common set of scales (e.g., to reveal the underlying structure of factors or dimensions in Discriminant Function Analysis).

	IMPLEMENTING EXPLORATORY SPATIAL DATA ANALYSIS METHODS FOR MULTIVARIATE HEALTH STATISTICS
		Scatterplot creation was accomplished by simply reading two fields of data from the polygon attribute file associated with the layer being mapped (in this case health service areas (HSAs)), and assigning the values in one field to the X axis and the values in the other to the Y axis.
		For instance, if the user had three separate scatterplots and wanted to see the geographic distribution of outliers on all three plots, she could select the outliers in one plot, move to the next plot and add the outliers from that plot, and then move to the third plot and add those outliers.
		On the scatterplot, this theme is classified along the Y axis, and is symbolized using different colors because the texture overlay cannot be implemented with point data.

		Scatterplot A has a an correlation coefficient of ____; Scatterplot B has a correlation coefficient of _____; Scatterplot C has a correlation of ______; Scatterplot D has a correlation of ______; and Scatterplot E has a correlation of ______.
		Scatterplot A has a correlation coefficient of r = +1.0; Scatterplot B has a correlation coefficient of r = -1.0; Scatterplot C has a correlation of r = +0.8; Scatterplot D has a correlation of r = -0.5; and Scatterplot E has a correlation of r = 0.
		Scatterplot E has no negative or positive slope and the points are widely scattered, so you can tell by these two things that there is no relationship between the two variables and the correlation coefficient equals zero.

(listed under "What programs, money, and staff are available?"), click on "Change your school or district" on the left, select your school or district, then click on link titled "Scatterplot" on the left side of the page.
		Scatterplots are considered by many to be one of the best tools for studying the association between two variables especially when you have a lot of data.
		Scatterplots may suggest an association between two variables because they are both associated with a third variable.

		The most common display of bivariate data is the scatterplot, which is an x-y graph of the data on which the x-coordinate corresponds to the value of one variable and the y-coordinate to the value of the other variable.
		The scatterplot can be used to help both in the validation of the initial data and in the understanding of later results.
		We will continue with this convention throughout the book; for scatterplots on which there is a known variable and an unknown variable, we will plot the unknown variable on the y-axis.

	Definition: Smoother for Scatterplot - TheMeasurementGroup.com
		In a scatterplot, a smoother (or a smooth) is trend line that shows how the two variables (X and Y) are related to one another.
		A smooth is not a statistical test of the relationship of X and Y, although in most cases it is possible to infer the practical significance of the relationship from examining the smoothed data.
		Smoothers are lines plotted onto a scatterplot to show the general trend of how the variables plotted on the X and Y axes of the graph are related to one another.

	Regression (Site not responding. Last check: 2007-11-03)
		Linear regression fits a line to a scatterplot in such a way as to minimize the sum of the squares of the residuals.
		In a scatterplot of weight against height, the x-coordinate of each point would be height of one person, the y-coordinate of that point would be the weight of the same person.
		In a scatterplot, the point whose coordinates are the arithmetic means of the corresponding variables.

	SPSS FAQ: How can I display overlapping data points on a scatterplot?
		This means that most of the data are stacked one on top of the other on the scatterplot, but we cannot tell how many observations each point on the scatterplot represents.
		To create the "sunflowers", a small line, called a pedal, is added to each point on the scatterplot to indicate how many observations each point represents.
		Another way to indicate how many data points each point on the scatterplot represents is to use jitter (adding or subtracting a small amount from each value so that the points are not exactly on top of each other).

	1.3.3.26.11. Scatterplot Matrix
		Although the basic concept of the scatterplot matrix is simple, there are numerous alternatives in the details of the plots.
		Scatterplot matrices are becoming increasingly common in general purpose statistical software programs, including Dataplot.
		If a software program does not generate scatterplot matrices, but it does provide multiple plots per page and scatter plots, it should be possible to write a macro to generate a scatterplot matrix.

	Scatterplot - Wikipedia, the free encyclopedia
		A scatterplot, scatter diagram or scatter graph is a graph used in statistics to visually display and compare two or more sets of related quantitative, or numerical, data by displaying only finitely many points, each having a coordinate on a horizontal and a vertical axis.
		A scatterplot can show three relationships, a positive (rising), negative (falling), and no relationship, which is varied.
		If the downward sloping pattern of dots is from upper left to lower right, it suggests a negative correlation between the variables being studied.

	Scatterplot
		A scatterplot is a useful summary of a set of bivariate data (two variables), usually drawn before working out a linear correlation coefficient or fitting a regression line.
		A scatterplot is often employed to identify potential associations between two variables, where one may be considered to be an explanatory variable (such as years of education) and another may be considered a response variable (such as annual income).
		A positive association between education and income would be indicated on a scatterplot by a upward trend (positive slope), where higher incomes correspond to higher education levels and lower incomes correspond to fewer years of education.
