Lies, damn lies and statistics – Mark Twain

He uses statistics as a drunken man uses lampposts - for

support rather than illumination.

Data LiteracyON YOUR TABLES, DISCUSS: DO YOU HAVE

1. Sufficient data:– to enable the key questions and factors to be explored

2. Sufficient access:– to systems which enable key elements of data to be linked

3. Sufficient experience and understanding:– to find the smallest amount of data needed - and how best to present it

4. Sufficient embedding:– such that individuals have an appropriate view about the reliability of

data5. Sufficient confidence:

– to be able to justify why we are NOT doing something as well as the things we have decided to do

6. Sufficient humility:– to enable our own assumptions to be challenged

How do they expect me to achieve that?

Different characteristics are used in complex mathematical models to create estimates based on a number of characteristics... Different estimates are created.

Differences• If two assessments are different

– One might be wrong

– They might BOTH be wrong

– They might be assessing different things
