# Median Value and Mean Value

Homework 4.2
1. [Submit on zyLabs] Write a function that has one input, array1, and two outputs output,
medianValue and meanValue. These outputs are as follows:
– medianValue is the median of the numbers in your array. The median is the number in the
array that has exactly the same number of values that are greater than or equal to it as it has
values that are less than or equal to it. In an array with an odd number of indices, this is a
value from the array itself. In an array with an even number of indices, this is the average of
the two middle values in the array. For example, for the array [5 8 9 1 0 2 3 1 9], the median
is [0 1 1 2 3 5 8 9 9] → 3. For the array [10 2 11 3 12 4], the median is [2 3 4 10 11 12] →
(4+10)/2 = 7. Note that the numbers before and after the median can be the same as the
median. The median of [1 2 2 2 2 2 2 2 2 2 3] is [1 2 2 2 2 2 2 2 2 2 3] → 2.
– meanValue is the average of all of the numbers in the array.
You should use a loop or multiple loops to find both of these, and you should NOT call either
of the following built-in MATLAB functions:
– mean
– median
– sum
– cumsum
Other functions, like mod, sort and length are allowed, and may be useful to you
