Math mean median mode

Mean, median, mode

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.
Median
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.
Median_value =(MIDLeft+MIDRight)/2
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, Median_value, MIDRight_value, ..., Max_value}

Now, was there something about fractions?
