Hi Shashwat,
"8" is a number, "Single" is not a number.
You can't use the Parse Number operator on this kind of data.

If you need numeric values you can i.e. use the "Nominal to Numerical" operator.

The Nominal to Numerical operator allows you to encode Nominal values, like your "Married, Single, Together, Divorced, Widow" values into either Unique Integers like "0,1,2,3,4" or into a dummy encoding, which means new attributes with either 0 or 1 for each of the possible Nominal values.
Here is an example processes that applies both methods onto your csv file:

you can copy and paste the xml into the Process panel of RapidMiner Studio.
This will replace your current process with the one from the XML, so please save your work first and start a new blank process first.
