When the value of one variable increases/decreases simultaneously with the other, it indicates a positive correlation, that is to say, they are positively related to each other. Since correlation is a measure of linear relationship, a zero value does not mean there is no relationship. Get in touch with us and we'll talk... Conversely, if the value of x increases/decreases and the value of y decreases/increases, x and y are said to be inversely proportional to each other. The word Correlation is made of Co- (meaning "together"), and Relation Correlation is Positive when the values increase together, and Correlation is Negative when one value decreases as the other increases A correlation is assumed to be linear (following a line).

For example, the number of classes a student misses is negatively correlated with his or her class grade. For example, when one stock is up, the other tends to be down. In statistical studies, a perfect negative correlation can be expressed as -1.00, a perfect positive correlation can be expressed by +1.00, and a zero correlation is expressed as 0.00. Let’s say, a comparative study is being done among a group of individuals who consume alcohol. Zero or no correlation: A correlation of zero means there is no relationship between the two variables. To understand why and how the above concept seems to be related to psychology, you need to understand correlational studies, which are often used as a measure to find out the relationship between variables in psychology.

The definition of negative correlation states that it is a relationship between two variables, such that when the value of one variable increases, the value of the other decreases and vice versa. Trying to figure out if there is a positive, negative, or no correlation? Negative correlation occurs when two variables move in opposite directions over a given time period. Correlation can take any value between -1 to 1. Negative correlation or inverse correlation is a relationship between two variables whereby they move in opposite directions. Pearson correlation takes a value from − 1 (perfect negative correlation) to +1 (perfect positive correlation) with the value of zero being no correlation between X and Y. In layman terms, Negative Correlation is a relationship between two variables. The variables are negatively related to each other. Negative correlation occurs when the rise in one item accompanies a fall in another. A perfect negative correlation has a coefficient of -1, indicating that an increase in one variable reliably predicts a decrease in the other one. That is to say, the more the absenteeism, lesser the grades. For example, suppose two variables, x and y correlate -0.8. But it will be wrong to suppose that the rise in ‘x’ is causing the ‘y’ to decrease because it is possible that both the companies concerned are involved in entirely different businesses and get impacted by different economic conditions.
