- The
**median**is also the number that is halfway into the set. To find the**median**, the data should first be arranged in order from least to greatest. To remember the definition of a**median**, just think of the**median**of a road, which is the middlemost part of the road. -

I could give you the answer but this website explains very nicely, how to calculate each type of average. The second example they use fits your list of numbers better than the first.

Mean Median Mode and Range

Mean Median Mode and Range

in math? mode is the number that comes up most often, mean is all the numbers added then divided by the number of numbers, and median you put all the numbers in order and pick the middle one

They are all measures of central tendency. See http://en.wikipedia.org/wiki/Average

The mean is 30, the median is 30, and the two modes are 30 and 31.

You don't need the calculator for that. Sort the data in ascending order.

Mode

Find the most frequent data element (the one repeated the most) in the set. That is the mode. If you have several elements that share the same highest frequency all of them are modes.

Count the number of elements in the set.

If the number of elements is ODD the median is the element that happens to hold the middle place in the ordered set.

If the number of data elements is EVEN, then there is not one middle element, but 2. Call them if you wish MIDLeft, and MIDRight

Take the values of these two elements and calculate their average.

That average is the value of the median.

You can imagine the median as a virtual (not really there) data element inserted between the two middle elements and having as value the average of the two middle elements

Your set would look like the following

{Min_value, ..., MIDLeft_value,

Now, was there something about fractions?

The question is incomplete.

The mean, also called the average is defined as

mean= (sum of the data values)/(number of data elements)

Mode = the most frequent data value (the one that is most repeated)

**To find the median: **

Data values 12.5, 13, 13., 13,**13.5**, 14, 19.5, 19.5, 20

**Mean** =(12.5+13+13+13+13.5 +14+19.5+19.5+20)/9=?

**Mode**= most frequent value. Here it is 13 (repeated 3 times)

There are 9 values, an odd number. Middle element is the 5th ( 13.5)

**Median**=13.5

Example 2

Data values 12.5, 13, 13., 13, 13.5, 14, 19.5, 19.5, 20, 25

**Mean** =(12.5+13+13+13+**13.5** +**14**+19.5+19.5+20 + 25)/10=?

**Mode**= most frequent value. Here it is 13 (repeated 3 times)

There are 10 values, an even number. Middle element is not among the values. There are two middle elements (the 5th and the 6th) or

The value of the median is the average of the 5th and 6th elements or

**Value of Median** =(13.5+14)/2=?

The mean, also called the average is defined as

mean= (sum of the data values)/(number of data elements)

Mode = the most frequent data value (the one that is most repeated)

- Order the data values in ascending order (sort them from the smallestr to the largest), and
- Locate the data value that is in the middle.
- If the number of data values id ODD (not a multiple of 2) there is only one middle element. That is the median.
- If the number of data elements is EVEN (multiple of 2), there is not one middle element but two.
- The median is the average of the two middle element values
**Median =( left of middle value +right of middle value)/2****Imagine this median value to be inserted between the two middle elements**

Data values 12.5, 13, 13., 13,

There are 9 values, an odd number. Middle element is the 5th ( 13.5)

Example 2

Data values 12.5, 13, 13., 13, 13.5, 14, 19.5, 19.5, 20, 25

There are 10 values, an even number. Middle element is not among the values. There are two middle elements (the 5th and the 6th) or

The value of the median is the average of the 5th and 6th elements or

mean: 77

median: 87

mode: none or all of them (take your choice)

range: 43

If this is homework, be sure to show your work.
