The F-distribution is used for interval data in cases where we are comparing the variances of two populations. The Student-t distribution is also used for interval data, but in cases where we are estimating the mean of a population based on a sample. The Chi-squared distribution is used for categorical data, and the Binomial distribution is used for binary data (e.g. yes/no questions). Therefore, the best choice for sampling distributions used for interval data is the F-distribution.
