My Name is Amy Moon and I am creating this web site for Algebraic Connections. This page will show you how to calculate each part of the big Seven, and help you with your Algebra!
First, I will
explain to you what each part of the Big Seven means:
1.
Mean- This is the average of all the numbers in your data
2.
Range- This is the smallest number in your data verses the biggest
number
3.
Maximum
(Max) – This is the largest number in your data
4.
Minimum
(Min) – This is the smallest number in your data
5.
Median- This is the number that ends up in the middle compared to all
other numbers in your data
6.
Average- This is the average of your data
7.
Mode- This is the number that is repeated the most
I will show you two ways to use the following terms to
your advantage!
Mode: Can be found by simply looking at your data and finding the number that occurs the most.
It can also be found by sorting out your data in categories from biggest to smallest. Then divide the remanding numbers by two.
Mean: Add up all numbers in your data and divide by how many numbers there are.
You can also push 2nd, Catalog, find mean, click enter. Then 2nd Stat to find the list you want.
Median: You can divide the smallest and largest into two categories and divide the remaining numbers. You can also find it, the same way as mean except find Median instead of Mean.
Max/Min: push 2nd, Catalog, find max/min and 2nd Stat, enter to find the list needed.
Average: Add up all the numbers and divide
by the amount of numbers. You can also use the same technique used in mean.
Range: look for the largest number versus the smallest number.
Example
7, 9, 11, 13, 15 is the list of numbers used
Average- add up
7+9+11+13+15= 55 Then divide by how many numbers there are. So 55 / 5 =11 is
the Average.
Range-
7(smallest) to 15(largest)
Min- 7
Max- 15
Mode- There are
no numbers repeated, so there is no mode
Median- when you
eliminate the seven and 9 for the smallest, and the 13 and 15 for the largest,
your middle number is 11
Mean- 11 is the
Mean (See Average for procedure)
This information can be very helpful to you in many ways. These
techniques can simplify data and make it easier to read. This can come in handy
with many jobs whether they are math related or not.
