Week 001 - Linear Regression

Linear regression makes a model of data, either with 2 variables (independent & dependent) or more. A line has the equation y = mx + b, where m is the slope of the line(steepness) and b is the y intercept (how far up or down the line starts). If you have a set of points (y, x) you can calculate the slope, m, using the equation below:

the bar symbol means arithmetic mean (average) the y intercept, b,can be calculated using:
