Is my usage of the colon in this sentence accurate?

Colon usage after an imperative sentence in survey instructions

• Consider a survey question that asks a question and then gives instruction about how to respond. For example, Is this a sample survey question? Check all that apply: __ yes __ no Is it best practice to end "Check all that apply" with a colon because a list of options follows, or a period because the sentence giving instructions is finished?

• Answer:

  I think that it is http://english.stackexchange.com/a/108630/41942 a good practice to separate an enumeration or an explanation and a clause that is to be enumerated or explained, with a colon. It acts like a logical separation of two parts. Another thing worth mentioning is that a http://english.stackexchange.com/a/15134/41942 should be treated differently: either list items should be separated with a semicolon, except for the last one terminated with a full stop, or each separate statement should be turned into a sentence with a capitalized letter and a full stop.
