Detailed explanation-1: -The slope of the line is positive (small values of X correspond to small values of Y; large values of X correspond to large values of Y), so there is a positive co-relation (that is, a positive correlation) between X and Y.
Detailed explanation-2: -We often see patterns or relationships in scatterplots. When the y variable tends to increase as the x variable increases, we say there is a positive correlation between the variables.
Detailed explanation-3: -Solution: A correlation close to 1 means that the graph shows an approximately perfect positive correlation. This means that graphically, this will show close to perfect increasing graph. In the given graph, the one that shows close to perfect increasing graph is scatterplot B .
Detailed explanation-4: -r = 1 means there is perfect positive correlation. r =-1 means there is a perfect negative correlation.
