Statistics; March 15, 2007

This is what we have learned in Applied Mathematics 40s March 15, 2007.

The class wants Mr. K to review or explain what we have learned yesterday March 14, 2007, because we didn't get it at first; well statistics is pretty confusing. Right after that conversation Mr. K showed us his yesterday's example.

Mr. K, re-explaining about the MEAN, MEDIAN, MODE, RANGE & STANDARD DEVIATION:

Mean: Remember that mean is the "average" for the total data we calculate.
To Calculate the Mean without a calculator.
" You add up all the the numbers and divide the answer by how many numbers you have on your data"

For Example:

Data: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

1+2+3+4+5+6+7+8+9+10 = 55

55 / 10 = 5.5

So the Mean is 5.5

Median: The median in exactly in the middle.

For Example:

Data: I, 2, 3, 4, 5

1, 2, 3, 4, 5

So 3 is the Median.

Mode: The mode is the often numbers you see on your data.

For Example:

Data: 1, 2, 2, 2, 2, 3, 4, 5

So 2 is the Mode.

Range: The range is the difference between the biggest number and the smallest number on your set of data.

For Example:

Data: 1, 3, 5, 7, 8, 13

13 - 1 = 12

So 12 is the Range.

Standard deviation:

SORRY....I'll do improvements later...

THE NEXT SCRIBE WILL BE........."BRITT"
