In my project work am comparing two signals with the help of an instrumentation amplifier. With the help of DSO (Digital storage oscilloscope) I read the output of instrumentation amplifier as 3.02 V. Can I display this output of Instrumentation amplifier to an LCD with the help of arduino. If yes, please help.
As you have not posted a link to the documentation for your DSO I have no idea.

DSO is not the factor. I will give an example:
Am comparing two dc voltages of 4 V and 5.2V with an instrumentation amplifier ic (INA129). if am giving the gain of ic be 10, then the output will be (5.2-4)*10 V = 12V. So mu question is, can I display this value from Instrumentation to an LCD with the help of arduino.
Yep, you can. As long as you bring it back to 3.3V/5V DC (depending on model). You can sample with about 10 kS/sec and 10 bit when using e.g. an Uno.
