The correlation coefficient = 6(20,485) – (247 × 486) / [√[[6(11,409) – (2472)] × [6(40,022) – 4862]]] = 0.5298 The range of the correlation coefficient is from -1 to 1. Our result is 0.5298 or 52.98%, wh

How would you describe the relationship between two variables that have a correlation coefficient of 0.577? A. Very strong B. Strong C. Moderate D. Weak E. Non-existent What is the correlation coefficient that most closely approximates the scatterplot below...
Correlation coefficient measures a relationship of a pattern between variables. A value of 0 means that there isn’t a relationship between two of the variables. A value of 1 means that there is a strong positive relationship. This means when one of the variables increases, the other also has...
For the dataset shown above, the correlation coefficient (the slope of this line) is −0.69 and the significance of the result is p = 0.026. This shows that duration of psychosis and performance IQ have a moderate to strong negative relationship with each other and that the relationship is...
The Pearson correlation coefficient is defined as a measure of the strength of the linear relationship between two variables. It indicates how close the relationship is to 1 or -1 for a strong linear relationship, while 0 signifies no linear relationship between the variables. ...
The correlation coefficient is a tool to help you understand how strong the relationship is between two different variables. When investing, it can be useful to know how closely related the movement of two variables may be — such as interest rates and bank stocks. You calculate the values...
However, there is only one correct answer. A Pearson correlation coefficient should accurately reflect the strength of the relationship. Take a look at the correlation between the height and weight data, 0.694. It’s not a very strong relationship, but it accurately represents our data. An accur...
