1.name a real-world situation where you might expect to transform data. describe the situation and how the data might be transformed.

2.the act of transforming (or manipulating) data is permissible because the same rule is applied to all data in a given set. in other words, you're not just transforming some of your data while leaving other data points alone. the same concept appears in algebra when isolating a variable to solve a given equation. as long as each step applies the same rule to both sides of the equation, it is permissible. even driving safely by car is possible because all drivers agree to drive on the same side of the road. can you think of two other examples where a similar logic might apply?

3.in this lesson you saw that transforming data is a powerful tool for gaining insight into the data. can you think of a situation for which you would not choose to transform the data? describe characteristics of the data set and why a transformation would not be appropriate.
