Who is the more consistent bowler? Standard Deviation

Question

At the end of a bowling tournament, three friends analyzed their scores.  Erinn's mean bowling score is 92 with a standard deviation of 14.  Declan's mean bowling score is 130 with a standard deviation of 18.  Matt's mean bowling score is 116 with a standard deviation of 22.

 

Who is the more consistent bowler?  Thank you :)

Answer 1

Standard deviation is a measure of how much a set of scores varies on average from the mean. A high standard deviation means the scores vary a lot from their mean. A low standard deviation means the scores tend to be closer together.

 

Does consistent mean clustered close together or far apart? This tells you whether you want the high or low standard deviation.
