Lots of other factors.

Lets say that there's 4 dollars in the pot, it's checked to you, you bet 4, and your opponent shoves over 8. Meaning you need to call 4 to win 16. You're getting 4-1 on your call. You can call with unmade hands that figure to win around 25% of the time.

Calling a check raise is typically bad for business unless you have the nuts or an extremely powerful hand, when the check raise isn't a shove.

In this situation, though, the check raise may have been because your opponent felt weakness because you bet less than half the pot.

Typically any bet you make should be between 50% and 100% of the pot. 66% of the pot should be your default if you don't know exactly what to bet.
