have been fitted to a data set, in order to identify the model that best fits the
population from which the data were sampled. Exact "**F**-tests" mainly arise when
the ...

situations. Unsurprisingly, the F-test can assess the equality of variances.
However, by changing the variances that are included in the ratio, the F-test
becomes a very flexible test. For example, you can use **F**-**statistics** and F-tests to

And then essentially figure out, what are the chances of getting a certain statistic
this extreme? And I haven't even **defined** what that statistic is. So we're going to
**define**--we're going to assume our null hypothesis, and then we're going to come
up with a statistic called the **F statistic**. So our **F statistic** which has an F ...

: "**What is** the probability that we'd get an **F*** **statistic** as large as we did, if the null
hypothesis is true?" The P-value is determined by comparing **F*** to an **F**
distribution with 1 numerator degree of freedom and n-2 denominator degrees of
freedom ...
