I'm trying to create a standard deviation formula based on 52 values. Unfortunately though, excel only accepts 30. Here's my formula:

STDEV(S7,U7,W7,Y7,AA7,AC7,AE7,AG7,AI7,AK7,AM7,AO7,AQ7,AS7,AU7,AW7,AY7,BA7,BC7,BE7,BG7,BI7,BK7,BM7,BO7,BQ7,BS7,BU7,BW7,BY7, CA7, CC7, CF7, CH7)

Excel then throws the "You've entered too many arguments for this function" error.

Does anyone know how I could set this up so I can use more than 30 values for this standard deviation?

Thanks.
