It's often also valuable to know to what degree they relate.
It is often important to know whether two collections of information relate to one another or form an observable pattern. Related: Inverse Correlation: Definition, How It Works and Examples Why are correlations important?įinding correlations between data sets can help you make informed decisions in the workplace. A perfect negative correlation would have a correlation coefficient of -1. Negative correlations work the same way as positive ones, but their correlation coefficients are less than zero. Negative correlations usually look somewhat like a line extending from the chart's top left to the bottom right. If one set of information decreases when the other increases, it is a negative correlation.

A perfectly positively correlated linear relationship would have a correlation coefficient of +1. When the figures increase at the same rate, they likely have a strong linear relationship. If you plot your data on a graph, a positive correlation would typically show a line extending from the lower-left corner of your chart toward the top right.įor positive correlations, the correlation coefficient is greater than zero. If one set of information increases when the other increases, that is a positive correlation. Here's a closer look at positive and negative correlations: Positive correlations Positive and negative correlations are descriptors for sets of numbers, or variables, that relate to one another in a linear pattern that you can recognize when you plot them as dots using a set of axes. Sometimes, you might see the correlation coefficient represented with the letter "p." It is important to remember that the correlation coefficient is most reliable when the relationship between your two sets of figures is linear, rather than curved, for instance. Using a correlation coefficient, you can determine if your data relates either positively or negatively. Positive and negative describe the type of correlation, or relationship, that exists between two variables or information sets.
