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.

Authority, Pseudoscience and Amy Cuddy

If you have stumbled upon TED talks or psychology news in the last five years, chances are you would have already read one of Amy Cuddy’s articles or watched her talks on ‘power posing’. Admittedly the argument that she weaves is actually convincing, and the simple fix she suggests to help with stressful situations most compelling. But what part of this claim is actually evidence based research, and what part is abusing authority to stretch scientific truth?

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.

On Having a Penis (Bone)

Technically speaking, a human penis can’t actually be ‘broken’. That’s because it’s made up not of bone, but of soft, spongy tissue. But what about animals? Do our close and not-so-close relatives possess boney penises? And if so, what is the function of a penis bone? The answer isn’t as simple as you might think.
