X,Y scatterplot

X,Y scatterplot. These are plots of X,Y coordinates showing each individual's or sample's score on two variables. When plotting data this way we are usually interested in knowing whether the two variables show a "relationship", i.e. do they change in value together in a consistent way?.

LINEAR REGRESSION

LINEAR REGRESSION. By: Emmalyn S. Sumpay MSCN. Linear regression is used to make predictions about a single value. Simple linear regression involves discovering the equation for a line that most nearly fits the given data. That linear equation is then used to predict values for the data.
