Hi everyone, I hope you can help me with this issue reggarding lists vs sets vs data sets
Take for instance the next question:
Number of goals where recorded as following: Set A ={2,2,2,6,6}
Set B={2,6,6}Quantity A: Std Dev of Set A
Quantity B: Std Dev of Set B
I think there are two interpretations:
- In Sets, order and repetitions does not matter, so QA=QB=2 (Std Dev of Set {2,6}).
- However, this is not any set but a “data set” which are really treated as Lists in GRE (according to this post), therefore: QA~1,96>QB~1,89.
Which one do you think is the correct approach?
Another example will be the following:
