Answer / babu
In Correlation the Dynamic Value is Generated by the Server.
In Parametrization the Value will be given by the Tester.

Answer / xyz
When one wants to perform the script’s actions like submit
using different values from those recorded. To do this, we
can replace the recorded values with parameters.
This is known as parameterizing the script.
Many applications and Web sites identify a session by the
current date and time. If you try to replay a script, it
will fail, because the current time is different than the
recorded time.
Correlation is a concept where we can capture the dynamic
data when it is generated and used throughout the script.

Answer / shirisha and sowmya
parameterization is used to replace the string with the
parameter and parameterization can be done in .csv data
file and common situations are data constraint,data cache
and data dependency..
correlation is used save the dynamic values during testing
session.

Answer / syed
Parameterization is done for User provided/ User defined
data.
Ex: In an script , I need to enter few ticket numbers.One
ticket number that I entered while recording the script is
hard coded . The saem hard coded ticket number would be
applied for all iterations during exceutio, that I dont
want . Instead , I need a different Ticket Number during
each iteration. So I would parameterize the hard coded
Ticket Number and Provide a set of different ticket numbers
in Order to apply a different one during exceution. This is
Parameterization.
Correlation can also be refered as parameterization.
However its not a parameterization of User Defined values
but parameterization of mServer generated values..

Answer / shiva
Correlation is capturing the dynamic values coming from the servers where as paramaterization is giving the data to the specific fields in the script

Answer / piyush singh
As as example, suppose we have recorded a script for login page with username: abc1 and password: Abc1
Now, while replaying the script you don't want the same hardcoded values in you script since that will not imitate the real world scenario.
So we will parameterized it by substituting it with a parameter say {username} and {password} and then we will modify the parameterization property and add rows and column in data file and select occurrence as either sequential or random.
On the other hand, when we send a request (for e.g. booking a flight) to server and in the response for each iteration server sends a dynamic session id or any dynamic value, then we will apply correlation here by using web_reg_param function or through design studio (automatic correlation) so that the dynamic value can be replaced by a parameter and script wouldn't get failed
