    So grateful for your videos. Your teaching style is so natural and suitable for 'stats idiots' like me :) I'm probably the one who's always raising her hand to ask a question but the teacher ignores/misses my raised hand. Most stats videos I've watched assume the viewer understands everything then jumps to the next level. But you actually take the time to make sure your point is understood before moving on. Thank you so much for your superb teaching!
