Suppose I have just results of various gaming sessions: Beginning
balance, Gaming EV (+ or -), Ending balance. No more info is supplied.
How can one get to the SD for the whole bunch of sessions. I assume
they all are from the same bankroll. So the question is: What is the
probability of the whole bunch of sessions to end to a higher balance
or to a lower one.
To clarify, here is an example of the data I could have
Beginning balance Session EV Ending balance
10000 +200 11400
11400 +50 11000
11000 +115 13000
and so on.
How could one infer from the data above a SD and / or the probility
for each supposed endiong balance for the whole list, given the list
of sessions the result of each sessions and the beginning balance.
Thank you very much
