[BlindMath] When making a graph, when is it appropriate to log adjust the values on the y-axis?

[Sabra Ewing]

Could the handout be wrong and the data actually is linear?

The handout states that we are to make a standard curve where we plot absorption values from spectrophotometry on the Y axis and different concentrations on the X axis in micrograms per milliliter. The problem is, this makes a linear graph that definitely is not a curve, and I’m wondering if it would be better to do some type of adjustment on the y-axis so that it is more user-friendly. I have seen this done on graphs before. When is it appropriate to log adjust the Y values, and how exactly is this done?
