storing data wirelessly received from an analog accelerometer

Hey Guys

I'm completely new to all this so apologies for the amateur question!

I have an analog accelerometer taking 10 recordings a second and I'm using two series 1 Xbees to transmit the data from just 1 axis to my Arduino Uno. How do I go about storing the incoming data to an array on the Arduino's memory (presumably with the EEPROM.write() function?) which I can then read and send to my laptop serial port after about 20 seconds?

Thanks in advice for any help! Using complete beginner terminology would be much appreciated!
