What?
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.
Stratified random sampling.

Frames are used by developers to divide the page into various sections. It can have id, name etc for referencing it further.

In stats, a sampling error is simply one that comes from looking at a sample of the population in question and not the entire population. That is where the name comes from. But there are other kinds of stats errors. In contrast, non sampling error refers to ANY other kind of error that does NOT come from looking at the sample instead of the population. One example you may want to know about of a non sampling error is a systematic error. OR Sampling Error: There may be inaccuracy in the information collected during the sample survey, this inaccuracy may be termed as Sampling error. Sampling error = Frame error + Chance error + Response error.

In Fireworks CS5, the "frames" panel can be found in the "Layers" panel. It allows you to manage the different frames of an animated GIF or PNG file. You can access it by clicking on the tab labeled "States" within the Layers panel.
