# 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.

# How To: Graphs

Virtually all scientific reports and articles deal with numbers of some sort, and what better way to represent large amounts of data than on a well made graph? Unfortunately not all graphs are created equal; this post will introduce the basics of graph building and common pitfalls to avoid.

# Liquid Helium – The Superfluid

The ability of helium in its liquid state to seemingly disobey the laws of physics has been the subject of study for almost a century. Yet this phenomenon is not commonly taught in schools, or even universities for that matter. What is occurring in the photo is a spontaneous process in which liquid helium rises up and out of its container. In this post I will attempt to explain the science behind this phenomenon in the simplest terms possible. Knowledge awaits.
