Many factors play a role in determining what kind of play you should adapt while short stacked in MTT. There is really no way to generalize in this context.
Questions you should ask yourself are:
1. How large are other stacks in comparison to mine?
2. What are the table manners?
3. What is my table image?
4. What stage is the tourney at? (mid, deep, bubble, ITM, etc.)
5. What cards have I been dealt for the last 30-40 hands?
Number 5 could help you speculate odds
of, perhaps getting better cards if you've been running dry for a while.
In any case, there are so many factors it's difficult to give one perfect solution.
