Question

choose the best way to improve this graph: the average yearly growth rate of pnw cedar trees compared to annual rainfall. growth rate (cm per year) amount of rainfall (cm) a the scale is not accurate for the data b the independent variable is on the wrong axis c the wrong type of graph is used for the data d independent and dependent variables are not in the title

Explanation:

The independent variable (amount of rainfall) should be on the x - axis and the dependent variable (growth rate) on the y - axis. Here, it seems the setup might be incorrect in terms of variable placement on axes. Also, the scale seems rather odd as the growth rate values on y - axis start from 200 and go up to 600 which may not be appropriate for cedar tree growth rate data. However, the most fundamental issue is likely with the axis placement of variables.

Answer:

b. The independent variable is on the wrong axis
