They say only 5% of Italians eat out on Sundays, while 95% are at home eating as much as humanly possible. Sunday lunch is usually spent at some relativesâ home, in my case my grandparentsâ.
A minus one indicates a perfect negative correlation, while a plus one indicates a perfect positive correlation. A correlation of zero means there is no relationship between the two variables. When there is a negative correlation between two variables, as the value of one variable increases, the value of the other variable decreases, and vise versa. In other words, for a negative correlation, the variables work opposite each other.
The relationship between x and y is 'perfect' for these two examplesâthe points fall exactly on a straight line or the value of y is determined exactly by the value of x. Our interest will be concerned with relationships between two variables which are not perfect.The 'Correlation' between x and y is r = 1.00 for the values of x and y on the left and r = -1.00 for the values of x and y on the right.hen we consider the relationship between two variables, there are three possibilities: 1  Both variables are categorical. 2  Both variables are quantitative. 3  One variable is categorical and the other is quantitative, for instance height and gender.
