**It is important to understand statistics**

It is important to understand the MEANING of statistics

By that I mean, when you are using statistics

it is necessary to understand what any statistic means

**Use and Misuse of Statistics**

It is important to understand:

- why people are using statistics
- how people are using statistics
- what the statistics user thinks their statistics mean.

It is important to understand the possibility of errors:

- in collection
- in the analysis
- in the ways the statistics are used / employed.

It is important to understand the limitations of the statistics.

- It is
*crucial*to understand what the statistics are trying to explain - What is the
*explanatory power*of these statistics? - Do they
*add to*the analysis? - In what way?
- On
*what*do they elaborate?
