There is a lot of comments about pool "bad luck". The following assumes that a block award is a random process.
1) Assume there are just five BTC pools with equal hashing power and you have ten miners. On average, every ten minutes one of the 5 pools will solve a block and receive 25 coins. If you divide up your miners and assign 2 miners to each pool, collectively your 10 miners will get something on average every ten minutes.
2) Assume that four pools control 40%, 30%, 20%, and 10% respectively of the BTC hash rate, then you would assign 4 miners to the first, 3 miners to the second etc etc. Still every 10 minutes you would get something.
3) In the real world, variance can never reach this ideal because some fraction of the hash rate is off limits, but the concept is still the same, to minimize variance, you would try to proportionately to distribute your mining power to the available pools.
Sometimes the comment is made that ghash.io is lucky because they mine a lot of coins, while forgetting that they control 40% of the network hash rate. With 40% of the network has rate they should mine a lot of coins. So it's not correct to directly compare the coin output of Ghash vs BTCguild without adjusting for their hash rates.
