Scatter Plots
Negative Correlation
A negative correlation means that there is an inverse relationship between two variables - when one variable decreases, the other increases. The vice versa is a negative correlation too, in which one variable increases and the other decreases.
Positive Correlation
A positive correlation is a relationship between two variables where if one variable increases, the other one also increases. A positive correlation also exists in one decreases and the other also decreases.
No Correlation
A scatterplot is used to represent a correlation between two variables. There are two types of correlations: positive and negative. Variables that are positively correlated move in the same direction, while variables that are negatively correlated move in opposite directions.
Line of Best Fit
A straight line drawn through the center of a group of data points plotted on a scatter plot. Scatter plots depict the results of gathering data on two variables; the line of best fit shows whether these two variables appear to be correlated.
Scatter Plot
a graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation present.
