LINEAR CORRELATION. The purpose of a LINEAR CORRELATION ANALYSIS is to determine whether there is a relationship between two sets of variables. We may find that: 1) there is a positive correlation, 2) there is a negative correlation, or 3) there is no correlation. These relationships can be easily visualized by using SCATTER DIAGRAMS.

Strong linear correlation: The closer the number is to 1 or -1, the stronger the correlation, or the stronger the relationship between the variables. Weak linear correlation: The closer the number is to 0, the weaker the correlation. Notice that for the perfect correlation, there is a perfect line of points. They do not deviate from that line.

Jan 01, 2018 · The linear relationship in the sample data is strong and reliable enough to indicate that the linear relationship is likely to be true in the population. We use the regression line to model the data and predict y values only if the following are satisfied: (1) if the correlation coefficient is significant

When there is a strong linear relationship, it means that the two variables tend to vary together in a predictable way, which might be due to something other than a cause-and-effect relationship. For example, the value of the correlation coefficient between sodium content and number of calories for the fast food items in the previous example ...

Pearson's correlation coefficient between two sets of numbers is a measure of the linear association between these two sets. It measures the degree to which two sets of data move together in a linear manner. A high positive correlation indicates a strong direct linear movement and a high negative correlation represents a strong inverse ...
