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.
If we consider the two variables price and purchasing power, as the price of goods increases a person's ability to buy these goods decreases (assuming a constant income). Correlation is a statistical measure (expressed as a number) that describes the size and direction of a relationship between two or more variables. A correlation between variables, however, does not automatically mean that the change in one variable is the cause of the change in the values of the other variable. Causation indicates that one event is the result of the occurrence of the other event; i.e. there is a causal relationship between the two events.
