A scatter plot (or scatter diagram) is a two-dimensional graphical representation of a set of data. Each x/y variable is represented on the graph as a dot or a cross. This type of chart can be used in to visually describe relationships (correlation) between two numerical parameters or to...

Typically, the Scatter Plot is used to plot Factor of Safety versus an input data Random Variable, to observe the correlation between the two.To create a Scatter Plot:Select Scatter Plot from the toolbar or the Statistics menu. In the Scatter Plot dialog, select the data you would like to...
This calculator constructs a scatter diagram (dot plot) that depicts the relashionship between two variables by putting each pair as point on the Cartesian plane. The values of variables are set as pairs of numbers separated by semicolons or tabs.
A scatter plot is used to determine whether there is a relationship or not between paired data. If y tends to increase as x increases, x and y are said to have a positive correlation And if y tends to decrease as x increases, x and y are said to have a negative correlation ...

In general terms, by looking at the scatterplot we can estimate the strength of the linear association between the two variables, but to get a precise magnitude, we need to compute the numerical value of the corresponding correlation coefficient. ...
