Stat Videos on YT

Here are some content creators on YouTube who I have used in the past to help me understand concepts in statistics and probability. Some of them are more organized than others (i.e., via playlists), but you could always try searching something like “[creator] central limit theorem” to find results

  • Khan Academy (good for everything)
  • Ben Lambert (good for stats)
  • Patrick JMT (good for math, some stats)
  • 3Blue1Brown (my personal favorite, especially his series on linear algebra)

If you have others that you have found useful, let me know and I will add them to the list
