Types of graphs
A graph is just a picture of an amount of something. Like size of buildings since 1900.
Your independent variable goes on X axis ( it is almost always time)
Your dependent variable goes on Y axis
Your X and Y axis scale can be different◦but the spacing between the numbers should be the same on an axis.
Graphs should have title, and descriptions on both X and Y axis.
In other words your graph should TALK
T titleA axis evenly spacedL label both axis and titleK key or legend if needed
Interpolation – is when you find a value that lies on the smooth curve or line between two actual data points.
Extrapolation – Find a value that lies on the smooth curve or line beyond the actual plotted points.
