How mirror can be identified by observing the values of the magnification? If an object is placed within the focal length of a mirror, the image of the object will get magnified in case of a concave mirror, and will get diminished in case of a convex mirror. The value of magnification will be greater than 1 in case of a concave mirror, and less than 1 in case of a convex mirror.

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.
