Variance Part 2

In this video we ask what the variance really means in practice. We show that two random variables can share the same expected value and still feel completely different, use a real-world employee example to make that contrast vivid — including the full variance calculation for each — and finish with two practical benchmarks that tell you exactly what high or low variance means.
