Non-surprisingly, a question mark indicates a question consisting of who, what, when, where, or why. It is usually placed at the end of a sentence.

In writing, the mark is used to have a point read out as a question, differentiating a real question from what is actually just a statement. For example:

Ride a bike? Never!

When it comes to direct quotes, put a question mark inside the quote:

"Yes?" she asked.

But if the whole sentence is a question, then put it right at the end. The same applies for parentheses.

Here's an example of how to use it when writing a quoted question that has a quoted statement:

"What did the chicken mean," the reporter wondered, "when she said 'It's a free country'?"

Indirect questions are embedded into declarative statements, so they do not have question marks.

A cool exception to note is the non-standard interrobang, which is a question mark and an exclamation point:
