Suppose the correlation coefficient between two variables is found to be 0.83. Which of the following statements are true?

small values of one variable are associated with large values of the other variable

the relationship between the variables is weak

a scatter plot of the points would show an upward trend

low values of one variable tend to be paired with low values of the other variable

there is a strong positive curvilinear relationship between the variables

there is a causal relationship between the variables

there is a strong suggestion of a positive linear association between the variables

Homework Answers

Answer #1

Following statements are true

A scatter plot of the points would show an upward trend.

low values of one variable tend to be paired with low values of the other variable.

there is a strong suggestion of a positive linear association between the variables.

Because the correlation coefficient is positive, scatter plot shows upward trend, there is linear association between variables. And 0.83 is high enough coefficient to show strong positive association not as strong as as correlation coefficient 1 will show. Low value of one variable will be associated with low value of other variable.

Scatter plot will be like this

When you are presented with a Pearson’s correlation coefficient between two variables for which an increase in one predicts a decrease in the other, and vice versa, the Pearson’s number will be zero; the Pearson number is only meaningful if the variables move in the same direction as one another close to -1 if the correlation is strong, negative but near zero if the correlation is weak close to -1 if the correlation is strong, close to +1 if the...

correlation measures the degree to which two variables are related to one another. Here are the definitions of the three possibilities: Positive correlations: In this type of correlation, both variables increase or decrease at the same time. A correlation coefficient close to +1.00 indicates a strong positive correlation. Negative correlations: This type of correlation indicates that as the amount of one variable increases, the other decreases (and vice versa). A correlation coefficient close to -1.00 indicates a strong negative correlation....

A Correlation Coefficient is a measurement of the relationship between two variables. A positive correlation means that as one variable increases, the second variable increases too. A negative correlation means that as one variable increases, the second variable decreases, or as one variable decreases, the second variable increases. Positive and negative correlations exists in nature, science, business, as well as a variety of other fields.
