What is a median in math?

What is a median in math? The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. Median is the middle number in a sorted list of numbers. To determine the median value in a sequence of numbers, the numbers must first be sorted, or arranged, in value order from lowest to highest or highest to lowest. If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above. If there is an even amount of numbers in the list, the middle pair must be determined, added together, and divided by two to find the median value. The median is sometimes used as opposed to the mean when there are outliers in the sequence that might skew the average of the values.  You may like What is manifesting? What is electric Charge?

Laws of Reflection

In the Figure Illustrates the terms that we use in the study of reflected

Represents the surface of a plane. AO, called the incident ray, is the
direction in which light falls onto the reflecting surface. O is the point
of incidence and OR the, reflected ray. The angles, which the incident
and reflected rays make with ON, the normal or perpendicular to the
reflected surface at the point of incidence, are, called the angles of
incidence and reflection respectively. Laws of reflection are -

♦ The incidence ray, the reflected ray and the normal at the point of
incidence all lie in the same plane.
♦ The angle of incidence is equal to the angle of reflection.
