CHART KEY

The colored bar shows the percentage of boys compared to girls for each response. However, if there are only a few responses for a question, the percentage can be misleading, so take note of the color-coding of the bar.

	100+ Responses: There are at least 100 responses to the question, so the results are probably worth paying attention to!
	10+ Responses: The lighter-colored bar shows there are between 10 and 100 responses. The results may or may not be useful.
	1+ Responses: The pale bar shows there are fewer than 10 responses, so you should probably ignore this one.
