It might be easier to compare Fixed Interval and Variable Interval in order to answer your question.
Fixed Interval - set amount of time (bird gets a cracker every 10 minutes if it pushed the lever.)
Variable Interval - no average time set (bird gets a cracker at some point after it pushes the lever, but the time varies)
Bird pushes lever = cracker in 20 minutes
Bird pushes lever = cracker in 7 minutes
Bird pushes lever = cracker in 11 minutes

Variable interval (VI) schedules deliver reinforcement for the first response after a random average length of time passes since the last reinforcement.
Example: VI3" = reinforcement is provided for the first response after an average of 3 seconds since the last reinforcement.
Lab example: VI10" = a rat is reinforced for the first bar press after an average of 10 seconds passes since the last reinforcement.
Real world example: a predator can expect to come across a prey on a variable interval scheduleSource(s): http://en.wikipedia.org/wiki/Reinforcement
