# data[].attributes.body
the relationship that occurs when the order of the elements is switched in the relation

# data[].attributes.body
the line is based of finding medians, rather than means, in regions of a scatter plot

# data[].attributes.body
a measure of the strength and direction of the linear relationship between two variables that is defined as the covariance of the variables defined by the product of their standard deviations

# data[].attributes.body
a linear approach for modeling the relationship between a scalar dependent variable y and one or more explanatory variables denoted x

# data[].attributes.body
a straight line drawn through the center of a group of data points plotted on a scatter plot

# data[].attributes.body
a simple method of interpolation that assumes a straight line relationship between points

# data[].attributes.body
when there is a relationship between two variables and your scatter plot will have an underlying trend in which the data is a straight line

# data[].attributes.body
uses horizontal and vertical axis to plot data points and show how much one variable is affected by another

two lines that are always the same distance apart and never touch.

# data[].attributes.body
the equation of a straight line in the form: y-y1=m(x-x1) where m is the slope of the line and (X1, Y1) are the coordinates of a given point on the line

# data[].attributes.body
process in which the value is estimated beyond the specific range of given variable
