K/D Ratio ..... Explain To Me ....

[Sparky862]

Okay, how do you work out the average K/D tario for a user in a group?? Lets take the example 0.67 and 1.67 .... How do you work out those 2 users average K/D per round/match??

Would be happy if you could answer it step by step and how you got to the average amount. I know K/D is your amount of Kills over One Life in game .... But is it your raw total of Kills over One life in game or your avarege Kills over One Life in game??

[Spawn of Totoro]

Take how many kills/death and how many rounds. Add the kills/deaths, divide by the number of rounds and you get the average.

This is how any kind of average is determined.

Also, to get the decimal versions, after the above is done, you divide your kills vs your deaths.

[Mac]

Sorry, I might be interpreting this wrong. Do you mean as a collective? Since you've mentioned 2 users and the K/D for them. If so just add up the K/D then divide by how many users. 0.67 + 1.67 = 2.34 then divide by 2 to get 1.17 as the average.

If not then what Spawn of Totoro said.

No.

That is ONLY how MEAN average is determined.

Other averages are determined by different methods, i.e. Median is identified as the central value if the entire data set is ordered from lowest to highest values, or the Modal average in which the most commonly occurring value(s) are usedf to identify an average.

Although MEAN is the most typical and common usage of average, it is neither the only, nor necessarily appropriate method to use given a situation.

A prime example of issues that may arise when using inappropriate methods, might be that of census results rom a few decades ago where it was establioshed by the Mean that the average family household (I believe in UK) would each have 2.4 children.
Naturally, this was nonsensical in real termsn, since NO FAMILEIES had or will ever have such a fractional child.

No, what i ment was

User A has a 0.67 KD
User B has a 1.67 KD

What is User A average KD per match/round
What is User B average KD per match/round

So i am talking about each individual user, not comparing them

But how can a KD be 0.67 .... How can you get 0 kills and 67 deaths?? But i have seen the user getting kills in a round (1-2 Kills) .... So how is it possible to have a KD of 0.67 when it should be 2.67???

Also that is how what average is determined?? His average death or kill rate per round??

[Hans]

0.67 means you get 0.67 kills per death on average, not that you have 0 kills and 67 deaths.
lets say you have a kd of 1.50, that doesnt mean you killed one and died 50 times, that means in lets say 2 lives you killed 3 people, so thats 1.50 per life.

So how do you get to that answer that 2 lives you killed 3 people which gives you a 1.50??

0.67 KD is the average number of kills per death for User A

This value could represent something like

User A has killed 2 players, but died 3 times.
It may also mean they have died 100 times, but killed 67 players.
Either way, it is not represent any average, but is merely the RATIO of kills per death.

Ratios can be expressed in verious ways, the word comes from the original Ancient Greek noption that RATIONAL NUMBERS can be expressed by the relationships of INTEGERS.


The following are all essentially the same ratio, expressed differerntly

0.67
67%
2:3
10:15

Typically, rations are expressed in their simpålest form. Since 10 and 15 can be divided by 5, 2/3 is a more typical representation than 10/15

In K-D ratios, these show the ratio of the total number of kills divided by the total number of deaths, but the result is again expressed in its simplest form.

In your case, the results are expressed as a decimal fraction where unity (1) woudl be 1 kill for each death.


_____________________

Since the 0.67 (and User B's 1.67) you have given as an example refer to the TOTAL OVERALL K-D rqatio (that is, the RATIO of the total Kills and Total Deaths)

If you seek to calculate the AVERAGE K/D ratio PER ROUND woudl then require the INDIVIDUAL K-D ratio for EACH ROUND.
It will NOT NECESSARILY BE THE SAME as the overall K-D ratio, since there may be rounds in which there were no kills, nor deaths for that user etc.

Here's an example:



R K D (Bear in mind, it will ONLY be possible to have maximum of 1 death per round)
0 0 1
1 0 1
2 2 1
3 0 0
4 1 1
5 0 1
6 0 1
7 0 0
8 1 0
9 0 0

in a match of 10 rounds, the player got 4 kills and died 6 times.
This gives a KD ratio of 4:6 or, in most simple terms, 2:3
This can be expressed as 0.67

HOWEVER The AVERAGE K-D is compeltely different. Assuming the MEAN average at least, this entails the individual round K/D

Sum{K} = 0+0+2+0+1+0+0+0+1+0 = 4
Sum{D} = 1+1+1+0+1+1+1+0+0+0 = 6

Mean K/Round = 4/10 = 0.4
Mean D/Round = 6/10 = 0.6

Mean K/D per round = 0.4/0.6 = 0.67

In this case, since the ONLY DATA is those ten rounds, the overall K/D is the same as the mean K-D per rounds of the match. HOWEVER, should User A play more matches, their match K-D may show differences.

personally never understood the obsecesion with the k/d ratio. it's not an accurate skill assesment in the general sense, only accurate to your performance within the scope of it's limits. you could get consitently matched with players far worse or far better than you on both sides, and this affects it. it does serve as a sort of easy to track number for games, but it's not a representation of fun.

I merely want to know cause I would like to know if i am improving or getting worse as a individual. I am the type of person that tries to improve and want to improve in what i do, and my K/D is the only way for me to keep track.

And I just struggle to grasp the term.

Sometimes i would go into another user profile and see a KD of 0.78, other times i see 1.46 and i just look at the numbers and i dont know how "good" he plays in a match. I just like to pit myself against other users to improve on myself

in a match of 10 rounds, the player got 4 kills and died 6 times.

--------------------------------------------------------------------------------------
0.67 KD is the average number of kills per death for User A
1.67 KD is the average number of kills per death for User B
-------------------------------------------------------------------------------------

So User A on average get 0 kills and 67 Deaths?? What?? I take it this is a higher value than the his average value like you said on a higher scale it can represent 100 deaths over 67 kills, which then makes sence. But the value of the K/D 0.67 makes no sence on average??

K ---- 0
D ---- 67

So in a game/round that user gets average (Full game consisting of best out of 5 Rounds)

K --- 0
D --- 10

????????????

-----------------------------------------------
HOWEVER The AVERAGE K-D is compeltely different. Assuming the MEAN average at least, this entails the individual round K/D

Sum{K} = 0+0+2+0+1+0+0+0+1+0 = 4
Sum{D} = 1+1+1+0+1+1+1+0+0+0 = 6

Mean K/Round = 4/10 = 0.4
Mean D/Round = 6/10 = 0.6

Mean K/D per round = 0.4/0.6 = 0.67
------------------------------------------------

If .......

Mean K/Round = 4/10 = 0.4
Mean D/Round = 6/10 = 0.6

Shouldnt my KD be 4:6 ... How do you get from 4:6 to 0:67??? How even?? Im so confused lol.

Also why is it 0.4 and 0.6?? Where does the 0 fit into that??

It still does not make sence to me at all.

[Sparky862]

Okay, the game im trying to make sence of is Tom Clancy Siege.

The game consists of best out of 5 rounds. Im still new to the game, so my KD is 0.67. So in a match on average i kill 2-3 people, but i died 2-3 times. Basicly for every person I kill, I die.

Sometimes on a match I kill 3 people, but died only 1 time.
Sometimes on a match I kill 0 people, but died 2 times
Sometimes on a match I kill 0 people, but died 0 times

So my avarege per match is a KD ratio of 2:2 or 2:3 ..... how does this game get to 0.67?? Yet when i gave you the total of 0.67 you were correct in your example claiming that on average the KD is 2:3 per round, which was correct. Yet i still dont know where the 0.67 comes from and where the 0 even comes from for that matter??

How do i rework my way from 0.67 KD back to a more average currency that makes more sence like 2:2 or 2:3??

I understand that 0.67 is a more broader scale which represents a number average of a 100 rounds total correct?? Because if a user had a KD of 0.99, and it went one number higher your KD would be 1:00 correct??

But if your KD is 0:67 or 1:67 or whatever KD you want to mention, how do I rework my way back to a more sensable number to know that on a avarege, this user will get x amount of kills and death according to hes KD which is 0:67 or 1:67?? For example if i join a user in a match on my team with a KD of 1:67, I can expect X amount of kills and deaths from him??

In your example you said that "Mean K/D per round = 0.4/0.6 = 0.67" ... how does that even make the slightest sence when it should be 0.10 not 0.67?? Plus where did you get that 0 from??

My current KD now is 0.77 ... so i went .10 higher than what i was
