Summary
| Description |
English: A plot of the scaled chi-squared probability distribution, the probability distribution of the sample variance s2,
where s2 is the mean of the squares of ν independent normal distributions of mean 0 and standard deviation σ; plotted here for the case σ = 1.0. Equivalently this is also a plot of the distribution of the variance ratio s2/σ2 for any value of σ. As ν increases s2/σ2 becomes more sharply peaked close to 1 |
