The correlation coefficient being +1 if the slope of the straight line...
Explanation:
The correlation coefficient is a statistical measure that shows the strength and direction of the relationship between two variables. The value of the correlation coefficient ranges from -1 to +1. A correlation coefficient of +1 indicates a perfect positive relationship between two variables. This means that as one variable increases, the other variable also increases.
Positive slope in a scatter diagram:
In a scatter diagram, a positive slope means that as the value of one variable increases, the value of the other variable also increases. This type of relationship is known as a positive relationship. When the slope is positive, it means that the line on the scatter diagram goes up from left to right.
Correlation coefficient of 1:
When the correlation coefficient is 1, it means that there is a perfect positive relationship between two variables. This means that as one variable increases, the other variable also increases, and the relationship between the two variables is very strong.
Conclusion:
Therefore, the correct answer to the given question is option A, which states that the correlation coefficient is 1 if the slope of the straight line in a scatter diagram is positive.
