An Introduction to Inference for the Ratio of Two Variances

An introduction to confidence intervals and hypothesis tests for the ratio of two population variances (using F procedures based on the assumption of normally distributed populations). I introduce the methods, and take a quick look at an example and discuss the results.
I don't work through any calculations in this video, but I have another video in which I work through a complete example.
The summary statistics and distribution of the 2D:4D ratios were estimated from Figures 1, 2, and 3 in:
Ozener et al. (2014). Inbreeding Is Associated with Lower 2D:4D Digit Ratio. American Journal of Human Biology. 26:183-188.
