An open circle should have a dashed circumference, a closed circle a solid one.
A closed circle is when a range of numbers also includes that number and an open circle is when a range of numbers doesn't include that number, :)
a semi-circle
With an open circle, the number at which the circle is is NOT included in the dataset; with a closed circle it is. For example if a line is drawn on the number line between 0.5 and 1.5 with a closed circle at 0.5 and an open circle at 1.5, then it represents the numbers between 0.5 and 1.5 including 0.5 but excluding 1.5; this range is the numbers which round to 1 to the nearest whole number.
