Activate - Week 2

I am going to do all my active blogs on the different topics of discussion first, and then fill in with my reading information. 

Correlation / Regression

In reference to my knowledge of math vocabulary, a correlation refers to a relationship between two scores or events. A correlation can be either negative or positive. A correlation coefficient determines the direction of the relationship.

A regression represents scores decreasing over time. Two events that have a negative correlation will show regression.

I think of a graph when I hear these terms. A positive correlation graph will show both the x-axis and y-axis numbers increasing. For example, a graph showing test scores on the y axis and the month of the school year will have a positive correlation if the test scores are increasing over time (what we want to happen). On the other hand, if test scores are decreasing over time, the y axis (test scores) will decrease while the x axis (time) will increase.
