Weak Positive CorrelationThe value of Y increases slightly as the value of X increases. Weak Negative CorrelationThe value of Y decreases slightly as the value of X increases. Complex CorrelationThe value of Y seems to be related to the value of X, but the relationship is not easily determine...
Correlation is a term that is a measure of the power of a linear relationship within two quantitative variables (e.g., height, weight). There are mainly two types of correlation depending on the movement of the variables − Positive correlation– In a Positive correlation of two variables, ...
What is a correlation coefficient and why is it used in statistics? Correlation Coefficient: When we measure the relationship between two variables, we may find that the change in the variables are related. The correlation coefficient measure how strong or weak this relationship is. However, ...
Example of a weak positive association. The correlation between blood viscosity and fibrogen is 0.46. Notice that there is also a tendency for small fibrogen values to have low viscosity and for large fibrogen values to have high viscosity. This tendency, however, is less pronounced than in ...
Answer and Explanation:1 The maximum possible correlation is represented by a Pearson coefficient is equal to +1. A value of +1 indicates that there is a perfect, positive,...

Correlation is usually defined as a measure of the linear relationship between two quantitative variables (e.g., height and weight). Often a slightly looser definition is used, whereby correlation simply means that there is some type of relationship betw
The further the coefficient is from zero, whether it is positive or negative, the better the fit and the greater the correlation. The values of -1 (for a negative correlation) and 1 (for a positive one) describe perfect fits in which all data points align in a straight line, indicating...
A negative correlation demonstrates a connection between two variables in the same way as a positivecorrelation coefficientand the relative strengths are the same. A correlation coefficient of 0.85 shows the same strength as a correlation coefficient of -0.85. Correlation coefficients are always values ...
