                                            WELCOME YOUNG INVESTIGATORS....

Your task to do....
Here's an interesting set of five numbers:     4,6,7,7,11
The mean, mode, median and range are all 7.

Can you find other sets of five positive whole numbers where:

Mean = Median = Mode = Range 
Can you find sets of five positive whole numbers that satisfy the following properties?

Mode < Median < Mean

Mode < Mean < Median

Mean < Mode < Median

Mean < Median < Mode

Median < Mode < Mean

Median < Mean < Mode

Not all of these can be satisfied by sets of five numbers! Can you explain why?

    I found a range of numbers where in all averages, the values are the same.
    4,4,4,2,6
    Total value when added altogether: 20
    Mean: 20/5=4
    Range: 6-2=4
    Median: 4
    Mode: 4
