They are still unbiased however they are inefficient since the variances are no longer constant. They are no longer the "best" estimators as they do not have minimum variance
Standard deviation (SD) is neither biased nor unbiased. Estimates for SD can be biased but that depends on the formula used to calculate the estimate.
ok I'm sure not many people will be asking this but a biased spinner is basically a spinner that is unfair or not accurate
Biased- (Not random) Unbiased-(Random) Example: (ubbiased) Woman takes random people to take a survey.
A biased error is one that is caused by a factor inherent to the source of the error. An unbiased error is one that comes from anywhere.
Leaning or tending to lean to one side.
One effect of non-response is that is reduces the sample size. This does not lead to wrong conclusions. Due to the smaller sample size, the precision of estimators will be smaller. The margins of error will be larger.A more serious effect of non-response is that it can be selective. This occurs if, due to non-response, specific groups are under- or over-represented in the survey. If these groups behave differently with respect to the survey variables, this causes estimators to be biased. To say it in other word: estimates are significantly too high or too low.
you can not people can be biased and not biased
Science is not biased.
I think that question was biased! It almost made me think you were biased! It should be obvious my answer is biased! Sometimes I think that I.Q. test questions are biased!
A biased sample is a sample that is not random. A biased sample will skew the research because the sample does not represent the population.
