- hervature 5y agoNegative correlation also known as anticorrelation does not mean there is a "direction". Simply, it is a scalar number and not a vector. Don't add to the confusion of terminology by using a colloquial definition of "direction" to mean it can be negative or positive. We could have defined correlation to be in [0,1] and your sense of direction would be very confusing.
- netizen-936824 5y agoThank you for the clarification, you are absolutely correct that its positive or negative rather than having a direction.
