Briefly [ha]:
(read the Wiki references)

Know the universe you are sampling, know the question, know what will confound your data, determine what to measure, decide what will be your acceptance criteria *before* you have the answers, design the sample procedure, identify systematic and non~ errors, do *NOT* assign causality just because you have some correlation, calculate your answers, see if they are reasonable and, [if you can afford the time and effort] re-test to confirm.

Then you have to be prepared to deflect and skewer the questions from the statistically challenged.

From Wikipedia, the free encyclopedia
The theory of statistics includes a number of topics:

Statistical models of the sources of data and typical problem formulation:

1. Sampling from a finite population
2. Measuring observational error and refining procedures
3. Studying statistical relations

Planning statistical research to measure and control observational error:

1. Design of experiments to determine treatment effects
2. Survey sampling to describe natural populations

Summarizing statistical data in conventional forms (also known as descriptive statistics)

1. Choosing summary statistics to describe a sample
2. Fitting probability distributions to sample data

Interpreting statistical data is the final objective of all research:

1. Common assumptions that we make
2. Likelihood principle
3. Estimating parameters
4. Testing statistical hypotheses
5. Revising opinions in statistics

read'em all, good luck.
