Find the equation that models the data. Select “LnReg” from the STAT then CALC menu. Use the values returned for a and b to record the model, y = a + bln(x). Graph the model in the same window as the scatterplot to verify it is a good fit for the data.

"WebSep 17, 2015 · A logarithmic model is a model that measures the magnitude of the thing it's measuring. It can also be seen as the inverse of an exponential model. For example, exponential growth is very common in nature for things like radioactivity, bacterial growth, etc., being written as N(t) = N_0e^(kt) or N(t) = N_0a^t So if wanted to know how much … " - Greenberg's logarithmic model
