And slowness of course. Enjoying a meal with friends or family is the main ingredient of any Italian dish. Italian Sunday lunches are the best example, a unique experience you should try at least once. 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 closer the coefficient is to either â1 or 1, the stronger the correlation between the variables. If the variables are independent, Pearson's correlation coefficient is 0, but the converse is not true because the correlation coefficient detects only linear dependencies between two variables. For example, suppose the random variable X is symmetrically distributed about zero, and Y = X2.
