An example of a strong negative correlation would be -0.97. The variables would move in opposite directions in a nearly identical move. The values demonstrate the strength of a relationship as the numbers approach 1 or -1. Numbers of 0.92 or -0.97 would show a strong positive and negative c...
The Pearson correlation coefficient is frequently referred to as r. This is because r is the value it takes when using statistical notation. This type of coefficient is standardized, which means it must fall within certain bounds. This is in contrast to a value, such as the...
