HP 48G Statistics question Ren Unregistered Posts: 272 Threads: 12 Joined: Jun 2007 08-25-2009, 11:30 AM Hello, In my Chemistry class we will be required to do statistical analysis (mean, std deviation, error, % error) on our lab experiments. I'm trying to use a HP48G to do this. In one of the sample questions the instructor has supplied, I need to calculate the above stats (mean, std deviation, error, % error) from this data (0.0064, -0.0169, 0.0201, -0.0096). Using the (right shift)STAT function, I entered the values, (checked Mean, Std Dev, and Total). The SD came out alright, but both Mean and Total came out 0 (zero) What do I need to do to get more decimal places? Right now in MODES my Number Format is in STD, But if I use one of the other modes (Fixed, Sci, or Eng) will I need to set the number of decimal places each time I'm given a different data set? Thanks, Ren dona nobis pacem Chuck Unregistered Posts: 320 Threads: 59 Joined: Dec 2006 08-25-2009, 11:43 AM I do believe the mean and total is exactly zero. No amount of decimals will change this.
