The answer is "Positive correlation".
Positive correlation is a connection between two variables in which the two variables move in tandem. A positive correlation exists when one variable reductions as the other variable decreases, or one variable increments while alternate increments. In insights, a flawless positive correlation is spoken to by 1, while 0 demonstrates no relationship, and negative 1 shows an immaculate negative connection.
An immaculate positive correlation implies that 100% of the time, the factors move by precisely the same. A positive correlation can be seen between the interest for an item and the item's related cost.
