The possible range of correlation coefficients depends on the type of correlation being measured. Here are the types for the most common correlation coefficients:
- Pearson Correlation Coefficient (r)
- Spearman's Rank Correlation Coefficient (ρ)
- Kendall's Rank Correlation Coefficient (τ)
All of these correlation coefficients ranges from -1 to +1. In all the three cases, -1 represents negative correlation, 0 represents no correlation, and +1 represents positive correlation. It's important to note that correlation coefficients only measure the strength and direction of a linear relationship between variables. They do not capture non-linear relationships or establish causation.

What else can I help you with?
Which of these correlation numbers shows the strongest relationship?
A correlation coefficient of 1 or -1 would be the highest possible statistical relationship. However, the calculation of correlation coefficients between non independent values or small sets of data may show high coefficients when no relationship exists.
What correlation coefficients represents a situation in which there is no relationship between variables?
We would need to have the list of correlation coefficients to respond to this question.
Is 0.17 the strong correlation coefficients?
No.
Which one of the following correlation coefficients indicates the weakest correlation?
None of them.
Which one of the following correlation coefficients indicates the weakest correlation Answer - 0.01 plus 0.021 plus 0.76 - 0.88?
Assuming that all of these coefficients are based on samples of the same size then the weakest correlation is -0.01 because its absolute value (0.01) is the smallest.
Define correlation coefficients?
Correlation coefficients measure the strength and direction of a relationship between two variables. They range from -1 to 1: a value of 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no correlation. They are commonly used in statistics to quantify the relationship between variables.
What are the properties of correlation?
The correlation coefficient is symmetrical with respect to X and Y i.e.The correlation coefficient is the geometric mean of the two regression coefficients. or .The correlation coefficient lies between -1 and 1. i.e. .

Properties of regression coefficient-statistics?
8.7.4 Properties of Regression Coefficients:(a) Correlation coefficient is the geometric mean between the regression coefficients. (b) If one of the regression coefficients is greater than unity, the other must be less than unity.(c) Arithmetic mean of the regression coefficients is greater than the correlation coefficient r, providedr > 0.(d) Regression coefficients are independent of the changes of origin but not of scale.
What correlation coefficients express the weakest degree of relationship between two variables?

What is a statistical measure of the strength of a relationship between two variables?
A statistical measure of the strength of a relationship between two variables is often quantified using the correlation coefficient, such as Pearson's r. This value ranges from -1 to 1, where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 signifies no correlation. Additionally, other measures like Spearman's rank correlation can be used for non-parametric data. These coefficients help determine how closely related the variables are and the direction of their relationship.
