Quandaries and Queries
 

 

Hi,
My name is Ade and I am a first year college student taking statistics. I came across a problem and I am wondering if you could provide the answer - I am trying to solve a standard deviation question, I have 30 data points to use, should I group the data before solving for variance or should I just use the raw data.

Thanks, Ade

 

 

Hi Ade,

Unless you are asked to group the data you should just use the raw data.
