Logarithmic transformations

In this chapter, you'll work with data on asteroids that are predicted to pass close to the Earth. It's good to be prepared!

Here you'll explore logarithm-transformations of data ("log" for short), which can be very useful if the values span several orders of magnitude.

• LOG10() takes a number or cell location, and returns the log, base 10.
• LN() does the same, with Euler's number ("e") as the base.
