Explanation
In a rather
technical technicality, this is the representation of information
for mean, median, mode and range.
Eh, I
really don't see difficulty in this, so it shouldn't be too
hard to explain. The mean is the average of a set of numbers,
and can be used to find a yearly stock percentage rise. Try
this: 10% 20% -60% 100% 25%. What is the mean of these numbers?
Mean can
also be used to discover grades in school.
The mode
is the number that appears most often, or the most common.
It can be used to find the most common height of students
in a classroom. Like this: 5''8, 6'1 4'11, 5'7, '5'7 5'9,
6'
5'7.
The range
is the difference between the largest and smallest number.
Such as rollercoaster legnths: 2,346 m, 1,200m, 3,987m, 678m.
The median
is the number in the middle of a set of numbers. Like these:
2, 6, 6, 7, 9, 12, 56, 8, 79
A way
to display a set of numbers is a stem and leaf plot.
Here is the set of data: 16, 15, 29, 23, 6, 8, 34, 24,
You would organize it as so:
Another
way to show a stem and leaf plot would be on Microsoft Excel,
Claris Works, or any other spreadsheet progam. You can also
show the mean in these programs by making a graph or chart.
