Good Afternoon Group,
Was just looking at a wb of the PB lottery results.
I used Excel to calculate the Mean, Standard deviation, upper and lower limits of each drawings range for the last 33 drawings.
The following are the results of this analysis:
Median |
13 |
25 |
33 |
49 |
59 |
12 |
Standard Deviation |
11 |
10 |
12 |
11 |
9 |
8 |
Lower Limit |
02 |
15 |
21 |
38 |
50 |
04 |
Upper Limit |
24 |
35 |
45 |
60 |
68 |
20 |
Range |
22 |
20 |
24 |
22 |
18 |
16 |
From the above analysis, the following numbers are the only ones that do not overlap by more than one drawing placement:
36, 37, 46, 47, 48
I then performed the same analysis at 10 drawings:
Median |
13 |
26 |
37 |
43 |
61 |
13 |
Standard Deviation |
13 |
11 |
12 |
11 |
12 |
8 |
Lower Limit |
00 |
15 |
25 |
32 |
49 |
05 |
Upper Limit |
26 |
37 |
49 |
54 |
69 |
21 |
Range |
26 |
22 |
24 |
22 |
20 |
16 |
From the above analysis, the following numbers are the only ones that do not overlap by more than one drawing placement:
There are none
Frankly, not being a statistician, I am a little surprised that this range of the drawings in the shorter term is greater than that of the longer term. This may be an anomaly, which is why I am reaching out to group to try and understand what I am seeing. Thought this might be something to look into, with a broader range at more drawings, vs a narrower range with fewer drawings, lending a thought process of drawings "filling the gaps".
Mathmeticians say that there is an equal chance of any number being drawn with any single drawing. Formulaicly speaking, in the long run, would agree. However, I do not believe that mathematics explain the increased frequency of number drawn in the short run that we often see.
Thoughts, comments? Am I way off course?
Thanks to all!!
