12.1 Scatter plot

One way to check for a relationship between two variables is to draw a scatter plot. One of the variables (independent/explanatory) can be on the x-axis and the dependent(response) on the y-axis. To draw a scatterplot of two variables x and y use the following code

import matplotlib.pyplot as plt
x = [x1,x2,...]
y = [y1,y2,...]
plt.scatter(x, y)
