QUESTION: Explain when you would use an F-test rather than a T-test in econometrics
When a statistical test is done to observe the accuracy in the
variances of two data set, with a large sample space is called
f-test.
T-test is done for hypothesis testing of a single data set along
with a defined sample or it can also be used to compare two data
set with their mean, when the standard deviation is not known.
