Question

How do i know when a graph is continuous or discrete?​

Answer 1

When looking at a graph, discrete data will have all the pints connected so it will look something like the 1st picture that I provided. Something that is discrete can not be broken down into decimals or fractions so we usually say discrete things can be counted.

On the other hand, continuous data is usually things that we associate with measuring. These types of graph will have dots all over them and they can have fractions and decimals in them.
