Math - Correlation

In this lecture we looked at how to draw a line of best fit through out data.

We also learnt how to calculate the coefficient of correlation, or r-value, which helps to show us how correlated our data is.
This can be quite an involved process, which involves finding the variance, covariance, and standard deviation of our two data sets but can be well worth the effort!

There’s a problem with the signs < and > in the 109 lecture

Great spot, thank you for pointing this out. I’ll get the videos updated asap.
