Especially do not hand in lots of spreadsheet data in an appendix. Put yourself in the position of the reader and have compassion on this person. And be sure to reference the source of your data, either in a footnote or an appendix. Interest rates are usually expressed as an annual percentage. Thus, there is no need to take logarithms of interest rates, since logarithmic transformations and first differences are used to change data to a rate of change.
Interest rates are, by definition, rates of return.
So do no take a logarithm and first difference of an interest rate. Furthermore, if the interest rates are expressed as percentages, and the non interest rates of growth are expressed as percentages, you will have to either divide the interest rates by 100, or multiply the non interest rates of growth by 100. Please do not make a mistake with this issue. Such mistakes can cost you lots of money. Nothing is more frustrating than to look at a graph and become even more confused about what is going on.
