Guys check out the following statistics related post from UKMi. I found some of the articles very useful.
UK Medicines Information is an NHS pharmacy based service. Its aim is to support the safe, effective and efficient use of medicines by the provision of evidence-based information and advice on their therapeutic use.
Number 1 (July 2001)
- Type and definition of data
- Precision in data measurement
Number 2 (August 2001)
- Samples and populations
- Intersubject variations
- Standard deviations
- Use of graphs to illustrate data
- Centiles and ranges
Number 3 (September 2001)
- Factors to consider when assessing a sample

Number 6 (April 2003)
Dealing with small samples
The t distribution
Using the t test to compare:
- a test value to a ‘normal’ value – (a one-sample t test)
- paired samples
- unpaired samples
Number 7 (August 2004)
