In a positive correlation, both variables increase together. An example of this is a company's profit's relationship with its sales. The greater the sales, the greater the profit. A negative correlation is where one variable decreases with increase in the other. An example is the time taken to reach somewhere and the speed traveled at. The faster you move, the less the time. No correlation means the two variables are not related. An example of this is as you get older, it does not mean you will get better grades.
A property was up for sale for $400,000 but there was so many offers and bids someone offered a million dollars, it was a positive thing for that owner knowing that extra cash will do well for them.
I got a job but I kept messing up then i got fired, all I feel is negativity.
There's no correlation when someone says that you look pretty one minute then turns to someone else and tells them the opposite of what they just told you.
