Discontinuous and Continuous Variation. Variation is all the differences which exist between members of the same species. There are two kinds of variation; continuous and discontinuous.You should be able to give some examples of each. Continuous variation is variation that has no limit on the value that can occur within a population. A line graph is used to represent continuous variation. Discontinuous variation is variation that has distinct groups for organisms to belong to. A bar graph is used to represent discontinuous variation.
