## Agent_Sniffles 3 years ago In probability, what is biased and what is unbiased?

1. ro.hitman

What do you mean? Independent and Dependent?

2. ro.hitman

I havent heard those terms

3. Agent_Sniffles

I was going thru the lesson and it said biased and unbiased. But, when I took my test, I only got one right so i guess I didn't really understand what it was.

4. ro.hitman

Im sorry, I dont know.

5. Agent_Sniffles

That's alright.

bias is when the likelihood isn't uniform... or the events are not equally likely as an example... a normal 6 sided die... has the numbers 1 to 6 on the faces... then the probability of any number is 1/6 P(5) = 1/6 P(2) = 1/6 etc in Bias a 6 sided die... with the numbers, 1, 2, 3, 4, 4, 4, the probability of each event has changed P(1) = 1/6 P(2) = 1/6 P(3) = 1/6 and P(4) = 3/6 this is bias... one evernt is more likely to occur

7. Agent_Sniffles

Well..then what's unbias? My math lesson explained that backwards. O_o

8. campbell_st

no bias... all events equally likely bias... one or several events are more likely hope that helps...

9. Agent_Sniffles

okay..Weird. It did help. Thanks ^)^
