9.1 - Linear Relationships - Statistics Online
Is the relationship linear or nonlinear? Is the relationship weak, moderate, or strong? Are there any outliers or extreme values? We describe the direction of the relationship as positive or negative. A positive relationship means that as the value of the explanatory variable increases, the value of the response variable increases, in general.
Does the scatter plot appear linear Strong or weak Positive or
Strong relationship: If the data points are very close to the line of best fit, the relationship is strong. Weak relationship: If the data points are spread out from the line of best fit, the relationship is weak. Here is a table summarizing the possible answers:

The linear relationship between two variables is positive when both increase together; in other words, as values of x get larger values of y get larger. This is also known as a direct relationship. The linear relationship between two variables is negative when one increases as the other decreases. For example, as values of x get larger values ...

Scatter Plot: Strong Linear (positive correlation) Relationship
The scatter about the line is quite small, so there is a strong linear relationship. The slope of the line is positive (small values of X correspond to small values of Y ; large values of X correspond to large values of Y ), so there is a positive co-relation (that is, a …
