Linear Regression of BMD Scanners
Objects may be more linear than they appear. Scholars investigate the relationship between the number of bone mineral density scanners in the US and time. Once they take the natural logarithm of the number of scanners, a linear...

Logarithmic Transformations of Data
Students investigate and study logarithmic equations. In this precalculus lesson plan, students analyze the data behind the function. They define each graph as positive, negative or no correlation. They find the line of best fit.
