Quote from video: Make sure you tick the box to show also experimental plugins. And then once that's ticked. Go back and search and the hotspot analysis plug-in should should appear. Now.

How to Analyse data in QGIS?

Click on the Processing ‣ Toolbox to open the analytical core of QGIS. Basically: all algorithms (for vector and raster) analysis are available within this toolbox. We start by calculating the area around the roads_34S by using the Buffer algorithm. You can find it expanding the Vector Geometry group.
