Sampling Interval is the inverse of sampling ratio. For instance, we want to sample 300 names from 900. After a random starting point, we select every third name of the 900 to get a sample of 300. The sampling ratio is 300/900 = 0.333 (or 33%) and the sampling interval is 1/0.333 which is 3.
Nope. Sampling time - is the amount of time it takes to obtain the sample. Sampling interval - is the period of time between samples. For example - it may take 10 seconds to obtain a sample. Obtaining a sample once a day is a sampling interval of 24 hours.
It is ratio.

It is the ratio between the size of the sample and the size of the population.
