**description of headers for Trivial Report**
Morocco,well done mate,keep up the good work.

I thought it'll be right from my side to give some input myself with a description of headers for Trivial Report.For an experienced lotto player these features are quite easy to understand,but a novice might struggle.For now,the description is mainly technical,what every header means and later we could discuss how to use the features as I think that everyone has some technique of their own.

Please if you notice any unlogical thing,correct me and add everything you think it should be added and/or changed.

Sum

Sum of digits of the draw
04 10 21 32 33 44

04+10+21+32+33+44=144

Med

Median is a middle value when numbers are sorted in ascending order i.e.for lotto 5 its a 3-rd number in line (middle), for lotto 6 its (n3+n4)/2, for lotto 7 its n4(4-th number),etc.

Code:

```
n1 n2 n3 n4 n5 n6
04 10 21 32 33 44
```

Med=(21+32)/2=26.5

Avg

Average of all digits
Sum/numbers drawn

In our case it is: 144/6=24

SD

Standard Deviation of the numbers
Variation is an average square deviation of the numbers from the middle,and standard deviation is a square root of that value.Hope that makes sense,I'm not a mathematician

Just for the record I'll show how its calculated,no need to know this really,though,

as LottoStatisticsXpl does all the work.

sd = square root [sum( x - xbar)^2 / (N-1)]

04 10 21 32 33 44

x - drawn number (4,10,21,32,33,44)

xbar - average (24)

square root[(4-24)^2+(10-24)^2+(21-24)^2+(32-24)^2+(33-24)^2+(44-24)^2)/(6-1)] = 15,2

SB

Small & Big numbers
Half of the numbers below midpoint are small numbers and the other half above the midpoint are big numbers

For 6/45: 1-22 are Small and 23-45 are Big

F.e.in this combination

4 10 21 32 33 44,ratio Small/Big is 3/3.

OE

Odd & Even numbers
Ratio of odd and even numbers in the drawn combination.

Code:

```
E E O E O E
04 10 21 32 33 44
```

so,obviously O/E is 2/4.

05

49

Ending from 0-4 and 5-9
-counts last digits in 2 groups: 0-4 and 5-9.

In example that follows there are 6 numbers that all end with a number from 0-4 so this relation is 6/0.

Code:

```
04 10 21 32 33 44
4 0 1 2 3 4
```

But,in this case you can see 4 numbers that have last digit from 0-4 and 2 numbers with last digit from 5-9 so a relation is 4/2.

Code:

```
09 10 17 23 32 43
0 3 2 3
9 7
```

Ending...

0123456789

Ending per digit
-counts specifically the last digits of the drawn numbers.

F.e.

Code:

```
04 10 21 32 33 44
4 0 1 2 3 4
```

0123456789

11112_____

123

How many from are

1=Single Digit

2=twice from this digit

3=3 times from this digit
Code:

```
04 10 21 32 33 44
4 0 1 2 3 4
```

123

41_

4 single digits (0,1,2,3)

1 twice from this digit (4)

_

or

Code:

```
06 12 16 30 31 36
6 2 6 0 1 6
```

123

3_1

3 single digits (2,0,1)

_

1 three times from this digit (6)

EN

Two or more from that digit
-specifies the exact two or more digit(s) endings.

Code:

```
04 10 21 32 33 44
4 0 1 2 3 4
```

In this case EN is 4 (two from that digit)

Rg

Range of the numbers
-in a sorted drawing,range is a difference between highest and lowest number drawn.

04 10 21 32 33 44

44 - 4 = 40

Co

Consequtives
Numbers that are next to each other.

Code:

```
Co
04 10 21 32 33 44 1 1 consequtive (32 33)
04 05 11 12 26 40 2 2 consequtives (4 5 and 11 12)
```

Re

Repeats from last draw
Repeaters are numbers that repeat from the previous draw.

Code:

```
445 14 09 03 04 10 21 32 33 44
444 07 09 03 09 10 17 23 32 43
....
```

In this case numbers 10 and 32 are repeaters.

R2-R12

Repeats after 2-12 last draws
This number shows how many repeaters did occur after 2-12 draws.

Deca

How many from each Decade
Decades are:1-9,10-19,20-29,30-39,40-49 and so on.

This feature shows how many numbers are drawn from each decade.

Code:

```
F.e.
1-9 10-19 20-29 30-39 40-49 Deca
04 10 21 32 33 44 11121
1 1 1 2 1
```

Ms

Decades that missed
-shows the number of missing decades.

In above example,no decade missed so the field Ms is empty.

BUT,in this case:

Code:

```
Deca
09 15 18 28 29 44 122_1
```

decade 30-39 is missing so Ms is 1... or another example...

Code:

```
Deca
04 09 11 16 31 38 22_2_
```

decades 20-29 and 40-49 are missing so Ms is 2.

Lex ID

The Lexicographic ID of this draw
Lexicographic ID is an ordinal number of particular draw combination in lotto game.This feature is useful for sorting of combinations.

For example,lotto 6/45 has 8145060 possible combinations.

First combination 01 02 03 04 05 06 has lex ID 1,

and the lex ID of the last combination 40 41 42 43 44 45 is 8145060.

H1...Hk

Last time appeared draws back
-shows how many draws back did number occur for the last time.If a value is 1,it means that a number is a repeater.

Code:

```
H1 H2 H3 H4 H5 H6
04 10 21 32 33 44 7 1 19 1 4 2
```

In this case,number 4 last appeared before 7 draws,numbers 10 and 32 are repeaters,21 last appeared before 19 draws,33 before 4 and 44 last appeared before 2 draws.

Sm

Sum of Since Last Appeared
Code:

```
H1 H2 H3 H4 H5 H6 Sm
04 10 21 32 33 44 7+ 1 + 19 + 1 + 4 + 2 = 34
```

Sum of last appeared in this case is 34.

LF

Leap Froggers ( +/- 1 off numbers of previous draw)
Leap froggers are numbers one up or one down off numbers from the previous draw,term "next number,next draw" also refers to this term as a synonim.

Code:

```
445 14 09 03 04 10 21 32 33 44
444 07 09 03 09 10 17 23 32 43
```

LF in this case are:10,33 and 44 because 9-->10,32-->33,43-->44.

Possible LF for the next draw are:

Code:

```
04 10 21 32 33 44
LF 03 05 09 11 20 22 31 32 33 34 43 45
```

In case that 2 numbers give the same LF (f.e 12 14 -->13),this is known as double Leap frogger and LottoStatisticsXpl will show that as repeating the LF twice: 1313.
