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?

Concept of Reflection

The idea that light travels in straight lines is uppermost, while its wave
character and other physical aspects are disregarded. Since the laws of
reflection and refraction corollaries of the wave nature. Sources of
light, such as the sun, stars, and electric lamps can be seen when the
light they produce reaches the eyes. However, most objects can only be
seen when light is reflected off the surface of an object. An object that
reflects no light appears to be black. On the other hand an object that
reflects all of the light appears the same colour as the light source, for
instance something which reflects all of the white light reaching it
from the sun appears white light mirrors and highly polished surfaces,
reflect light strongly and we shall now deal with the laws governing
the reflection.
