This shows us some of the probability density functions for some of the chi-squared distributions. This first one over here, for k equal to 1, that's the degrees of freedom. So this is essentially our q1. This is our probability density function for q1. And notice, it really spikes close to 0, and that makes sense, because if you're sampling just once from this standard normal distribution, there's a very high likelihood that you're going to get something pretty close to 0. And then if you square something close to 0, remember, these are decimals, they're going to be less than 1, pretty close to 0, it's going to become even smaller. So you have a high probability of getting a very small value.
