How To Date A Dinosaur Fossil

No, not that kind of dating… Rather, ‘dating’ a dinosaur bone dug out of the ground involves a series of processes that allow us to estimate just how long the thing had stuck around on this Earth. This helps us to understand how that species fits into the evolutionary tree of change; when did they first appear and when did the last of their kind walk this Earth? Let’s take a look at the chemistry that allows us to travel 65 millions years back in time.

How To: Statistics – ANOVA

One thing that regularly stumps scientists is the handling of data. We seem to be very good at generating obscene amounts of it, but representing it meaningfully can be a little off putting if you don’t happen to be a bioinformatician. In previous tutorials we looked at hypothesis testing using variations of the t-Test, and we continue the series by comparing more than 2 samples sets with ANOVA.

How To: Statistics – Two Sample and Paired t-Tests

One thing that regularly stumps scientists is the handling of data. We seem to be very good at generating obscene amounts of it, but representing it meaningfully can be a little off putting if you don’t happen to be a bioinformatician. Let’s continue our tutorial series by introducing Two-Sample t-Tests and Paired t-Tests to see how we can easily incorporate statistical analysis into our work.

How To: Statistics – One Sample t-Tests

One thing that regularly stumps scientists is the handling of data. We seem to be very good at generating obscene amounts of it, but representing it meaningfully can be a little off putting if you don’t happen to be a bioinformatician. Let’s wet our toes with a simple One Sample t-test to see how we can easily incorporate statistical analysis into our work.
