 # Lab 0 - Statistics and the Student t-test
+
+We use statistics to draw conclusions from limited data. No measurement is exact. Every measurement you make has two types of uncertainties, *systematic* and *random*. *Systematic* uncertainties come from faults in your assumptions or equipment. 
+*Random* uncertainties are associated with unpredictable (or unforeseen at the
+time) experimental conditions. These can also be due to simplifications of your
+model. Here are some examples for caliper measurements:
+
+In theory, all uncertainies could be accounted for by factoring in all physics
+in your readings. In reality, there is a diminishing return on investment
+for this practice. So we use some statistical insights to draw conclusions.
