Senior Mathematics Faculty Interview Questions and Answers

Cumulative frequency is the running total of the frequencies in a frequency distribution.

• Cumulative frequency is calculated by adding up the frequencies as you move through the data.

• It helps in determining the number of observations that lie below a certain value in a data set.

• Cumulative frequency can be used to create cumulative frequency distribution or cumulative frequency polygon.

• For example, if the frequency of a certain value is 5 and the cumulative frequency up to that...read more

A quadrilateral is a polygon with four sides and four angles.

• Quadrilaterals can have different types of shapes such as squares, rectangles, parallelograms, trapezoids, and rhombuses.

• The sum of the interior angles of a quadrilateral is always 360 degrees.

• Opposite sides of a quadrilateral are parallel in parallelograms.

• Examples of quadrilaterals include a square, rectangle, and kite.

A rhombus is a quadrilateral with all sides of equal length and opposite angles equal.

• A rhombus has four sides of equal length.

• Opposite angles of a rhombus are equal.

• The diagonals of a rhombus bisect each other at right angles.

• Example: A square is a special type of rhombus with all angles equal to 90 degrees.
