In mathematics when it comes to graphs preparing and reading them accurately is enough to solve any question that arises from it. Scatter plots and time series graphs are descriptive graphs that show changes in a variable over time. How good are your reading skills? Answer the questions below and find out.

The beetle population is the independent variable.
The number of trees is the depedent variable.
The beetle population is the depdent variable.
Botht the beetle population and the number of trees are independent variables.
A greater number of trees indicates a higher beetle population.
The number of beetles in an area is dependent upon the number of trees in that area.
There is a positive correlation between the number of beetles in an area and the number of trees.
There appears to be no correlation between the number of trees in an area and the beetle population.
Beetles breed more slowly than trees.
The beetle population increases more rapidly than the tree population.
Trees will become extinct after 40 years.
The number of trees is greater than the number of beetles after 40 years.
