Crazy Google Positioning Results?

[jeromy g]

I have been getting crazy search positioning results for my website. One minute I'm listed on page 1 of the search result and have been as high as the #1 position and the next minute I am as far back as on the bottom of page 5. I am still relatively new to SEO, but I have not had this problem with any of the other keywords that I have gone after in the past. At the time of writing this I am currently found in the middle of page 4.

All I want to know is why is there such a big swing in Google's search results. They just seem to be all over the place with no rhyme or reason.
