Central vertigo and dizziness are symptoms of a disorder or disease that is affecting the brain or brain stem. Both vertigo and dizziness can affect your sense of motion and balance and ability to perform some activities such as driving.
A scatter plot, scatterplot, or scattergraph is a type of mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data.If the points are color-coded you can increase the number of displayed variables to three.or a set of data variables (dimensions) X 1, X 2, ... , X k, the scatter plot matrix shows all the pairwise scatter plots of the variables on a single view with multiple scatterplots in a matrix format. For k variables, the scatterplot matrix will contain k rows and k columns.
Scatter Plots and Linear Relationships. A helpful way to visualize a relationship between two variables is to construct a scatter plot, which you were briefly introduced to in our discussion of graphical techniques. A scatter plot represents each set of paired scores on a two dimensional graph, in which the dimensions are defined by the variables.
