anonymous · Answer

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.

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

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

campbell_st · Answer

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