This software functions online,
directly from this website, and it calculates the Correlation Coefficient
of two data sets. Each data set may have up to 100 numbers.



In the following instructions, the
data sets are referred to as the Pink and Blue data sets, which correspond
to the colors of the input boxes. Thus to use this software,
defined one of your data sets as Pink and the other as Blue.
Then, scroll down and you will see a set of pink input boxes on the
left, and a set of blue input boxes on the right. Then enter
the Pink data set in the pink input boxes, and the Blue data set in the
blue input boxes. 


Before entering or deleting numbers in an input
box, you must first left click on it. 


When you enter numbers,
you must start at the top input box, and work your way downward.
For each, number you place in a pink input box, you must place a
number in the adjacent blue input box. The data sets you
enter must occupy an equal number of input boxes. By design,
this software will not perform calculations when it encounters error
conditions, such as the above. 










This software has a controllable
rounding mechanism that rounds all the 


calculated results down to 

decimal places. You can change
this 





decimal places you prefer in the above input
box. 








The Correlation Coefficient for the Pink and
Blue Data Set is: 





The following is an unconventional way of
presenting correlation 


The correlation between the Pink and Blue data
sets in PERCENT is: 





Column for the Pink data set 
Column for the Blue data set 










In the narrow pink column on the right enter the
numbers for the Pink Data set. OPTIONAL: In the wide pink
column on the left, you can enter a descriptive word or phrase, or other
information, for each number you enter, such as the name of a test
subject, or the individual that collected the data. 
In the narrow blue column on the right
enter the numbers for the Blue Data set. OPTIONAL: In the wide blue
column on the left, you can enter a descriptive word
or phrase, or other information, for each number you enter,
such as the name of a test subject, or the individual that
collected the data.
