How can you tell from a scatter plot wheather two variables have a positive correlation a negative correlation or no correlation?
Positive correlation = the slope of the scattered dots will rise from left to right (positive slope) Negative correlation = the slope of the scattered dots will fall from left to right (negative slope) No correlation = no real visible slope, the dots are too scattered to tell.
How do you tell wheater a slope is positive or negative?
A slope is positive or negative based on if the line goes from the upper left corner down to the lower right corner or right to left. Left is positive right is negative.
For a negative slope the rise is and the run is positive?
For a negative slope, the rise is negative and the run is positive.
How can you tell from a graph on a line what type of slope it has?
If the line slants up and to the right, it has a positive slope. If it is slanting up and to the left, it has a negative slope.
What is the difference between positve and negative correlation?
Positive correlation has a positive slope and negative correlation has a negative slope.
