If you remove some values from the data set, the correlation coefficient will typically be changed. The direction and magnitude of the change will depend on the values of the values removed.

What is the correlation coefficient to use for ordinal versus nominal data?

What does a correlation coefficient of 1.1 mean?

Well, friend, a correlation coefficient of 1.1 is not possible because correlation coefficients range from -1 to 1. If you meant 1.0, that would indicate a perfect positive linear relationship between two variables. It means as one variable increases, the other variable also increases proportionally.


What is an example of correlation coefficient?

Correlation coefficient My understanding is: two variables as they relate to one another and how accurately you can predict their behavior to one another when together. Basically the strength of the linear association between two variables. When the variables have a tendency to go up and down together, this is a positive correlation coefficient. Variables with a tendency to go up and down in opposition, (one ends up with a high value and the other a low value) this is negatiove correlation coefficient. An example would be the amount of weight a mom gains during pregnancy and the birth weight of the baby


How would you interpret the findings of a correlation study that reported a linear correlation coefficient of 0.3?

A linear correlation coefficient of 0.3 indicates a weak positive correlation between the two variables being studied. This suggests that as one variable increases, there is a slight tendency for the other variable to increase as well, but the relationship is not strong. It is important to note that correlation does not imply causation, and other factors may influence the relationship. Further research would be needed to explore the nature of the relationship more comprehensively.


What correlation coefficient is most likely to describe the relationship between brushing one's teeth and the number of cavities one gets?

The correlation coefficient most likely to describe the relationship between brushing one's teeth and the number of cavities is expected to be negative. This is because more frequent tooth brushing is generally associated with fewer cavities, indicating that as one variable increases (tooth brushing), the other variable (number of cavities) decreases. Thus, the correlation coefficient would likely be close to -1, signifying a strong inverse relationship.

What does a strong negative correlation coefficient mean?

The graph follows a very strong downward trend. Would have helped if you specified which correlation coefficient; there are different types.


When two variables are found to be unrelated the correlation coefficient would be?

Zero.


Which correlation coefficient indicates the weakest relationship between variables?

Pearson's Product Moment Correlation Coefficient indicates how strong the relationship between variables is. A PMCC of zero or very close would mean a very weak correlation. A PMCC of around 1 means a strong correlation.

How would you describe a Correlation Coefficient in your own words?

The strength of the relationship between 2 variables. Ex. -.78


What value or benefit would a researcher gain by calculating a correlation coeffcient rather than simply describing the relationship as a positive correlation or a negative correlation?

The correlation coefficient gives a measure of the degree to which changes in the variables are related. However, the relationship need not be causal.

What can you say about the correlation coefficient and the correlation description when the points lie exactly on vertical or horizontal line?

Let me rephrase: Case 1: You have x and y variables, but the values for x is a constant (vertical line) Case 1: You have x and y variables, but the values for y is a constant (horizontal line) Result is that you have zero covariance, so a correlation coefficient can not be calculated because that would cause a division by zero. If one of your x value (Case 1) or y value (case 2) is not exactly the same as the others, then a correlation coefficient can be calculated, but does it mean anything? The correlation coefficient indicates a linear relationship between two random variables, not between a constant and a random variable.


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.
