Question

if the relation between x and u is 3x+4y+7=0 and the corelation coeffi ient between x and y is -0.6
what is the relation between x and y​

Answer 1

The relationship between x and y is a strong negative relationship.  

Explanation:

• The value of the correlation coefficient is used to measure how strong a relationship between two variables.
• The coefficients of correlation vary from -1 to 1.
• The strong negative correlation means that the graph has a slope in the downward direction from left to right.
• As the x-values increase, the y-values get smaller.
• The strong positive correlation means that the graph has a slope in the upward direction from right to left.
• As the x-values increase, the y-values get larger.
• Here, the given value of the coefficient of correlation is -0·6.
• Therefore, the relationship is a strong negative relationship according to Pearson's Correlation.
