Bivariate Correlation
Pearson’s correlation coefficient is a statistical tool used to measure bivariate correlation. This refers to the strength and direction of the linear relationship between two variables. It assesses how much one variable tends to change along with the other.
A positive correlation indicates that as one variable increases, the other tends to increase as well. Conversely, a negative correlation suggests that as one variable goes up, the other tends to go down. A value of zero indicates no linear relationship between the variables.
Pearson Correlation Coefficient
Pearson Correlation Coefficient: Correlation coefficients are used to measure how strong a relationship is between two variables. There are different types of formulas to get a correlation coefficient, one of the most popular is Pearson’s correlation (also known as Pearson’s r) which is commonly used for linear regression.
The Pearson correlation coefficient, often symbolized as (r), is a widely used metric for assessing linear relationships between two variables. It yields a value ranging from –1 to 1, indicating both the magnitude and direction of the correlation. A change in one variable is mirrored by a corresponding change in the other variable in the same direction.
