The sum of the interior angles of a regular polygon is 2n-4 right angles where n is the number of sides.
If n = 180, then 2n - 4 = 360 - 4 = 356 right angles.
Each interior angle therefore measures 356 x 90 ÷ 180 = 178°.
The central angle of each segment of this polygon therefore measures 180 - 178 = 2°.

To calculate the measure of a central angle of a regular nine-sided polygon, divide 360 degrees by the number of sides. In this case, divide 360 by 9. The measure of the central angle of a regular nine-sided polygon is 40 degrees.
There are two modes! that is one of the main weaknesses of the mode as a measure of central tendency.
School grades, yes. Not so sure about greads, though.

It is one measure - not the only one - of a "central tendency". It is the same as the "average". To calculate the average, just add all the numbers, and divide the result by the amount of numbers.
