## Main Question or Discussion Point

So I work at a retail store, and the way the company works, they determine how many hours are given to each store by the amount of sales that is predicted for this week. The higher number of sales, the higher number of hours = more workers.

the way that the company predict how much we will make this month is this: so lets say the company wants to forcast how much money they will make in the month of August 2005. They take the sales of August of 2002 + Sales of August 2003 and find the average. that average, is how much we are predicted to make in 2005

so (n-2 + n-1)/2 is the prediction for month n..

Being a math major, I was thinking, is this mathematically sound way to predict forcast?

Im sure there are statisticaly better way to predict forcast right? what would be a more accurate way to do it? Since I have access to old records(and have taken a number of statistics and math classes), I was wondering if it is possible for me to give a better prediction.

thanx guys
