Keep in mind that correlation doesn't always equal causation. If you're looking to determine a negative correlation, these two datasets are likely to move in opposite directions. Your variables are the two things you want to measure the correlation or relationship between. If you want to determine the correlation of your negatively correlated variables, here are some steps you can take: 1.

Related: What Is a Positive Correlation in Finance? How to determine negative correlation A portfolio of exclusively positive correlations could prove volatile, so it's important to maintain negative correlations in a portfolio, too. Some believe that you can reduce risks in a portfolio by maintaining uniquely correlated financial assets. Often, portfolio managers look at correlation to help them diversify their portfolios. One reason is that it can help portfolio managers reduce risks within their asset holdings. There are many reasons why knowing the correlation coefficient between variables is important. Related: Correlation Coefficient Formula: A Definitive Guide Why is negative correlation important to understand? The higher the negative correlation is, the closer you can expect the correlation coefficient to be to -1. If they had a correlation coefficient of -0.1, that would mean they had a weak negative correlation. That said, if two datasets have a correlation coefficient of -0.8, they would have a strong negative correlation. A correlation coefficient of -1 represents a perfect negative correlation, +1 represents a perfect positive correlation and 0 represents no correlation. The correlation coefficient measures the strength of the relationship between two variables. Related: What Is a Data Set? (With Definition, Types and Examples) What is a correlation coefficient? The less you sleep, the more soda you might drink. The more money you spend, the happier you can be. The higher the room temperature, the lower the rabbit population The more you cook, the smarter you may be. The more you exercise, the more you sing. As one variable moves one way, the other moves in a different, or unrelated, direction. Here are some examples of zero or no correlations: Related: Positive and Negative Correlations (With Definitions and Examples) Zero or no correlationĪ correlation of zero means there's no relationship between the two variables. The more the temperature rises, the higher the lemonade sales rise. The more hair you have, the more conditioner you may use. The more money you make, the more you might pay in income taxes. The more you eat, the more groceries you may buy. Here are some examples of positive correlations: This means that both variables increase or decrease simultaneously. Represented as 1, a positive correlation shows variables moving in the same direction. Here are other types of data correlation: Positive correlation Negative correlation is just one statistical term used to identify data relationships between two variables.

The lower the temperature, the more clothes you may wear. The more you cook at home, the less you might eat out. The more it rains, the less you can water the garden Here are some examples of negatively correlating variables: Even though two variables might have a negative correlation, things could change as time passes.

This is can be especially true with stocks and bonds. It's important to note that in some circumstances, correlations might change. Related: Inverse Correlation: Definition, How It Works and Examples Negative correlation examplesĬonsider the following variable examples that would produce negative correlations. This is the opposite of positive correlation, where both variables increase or decrease at the same time. The reverse can also be true with a negative correlation. This shows that while x, or the first variable, gains value, y, or the second variable, decreases in value. You might see negative correlation represented with a -1. Negative correlation, or inverse correlation, describes a situation where, with two variables, one variable increases in value while the other decreases. In this article, we discuss negative correlation and its differences from other correlation types, and we offer steps for calculating negative correlation and examples of negatively correlated variables. There are many types of correlations, and understanding how each one works can help statisticians, managers and other professionals discover the relationships between the variables they study. Correlation is a statistical term that describes the relationship between two variables or datasets.
