Comments Biased and unbiased estimators from sampling distributions examples

I have a question how do we tell the sample median is biased or unbiased if we don't know the population median? is it possible? Comment from : Ahmad Fauzan

Thank you for this great video Just one point of clarification for me (I'm learning statistics for the first time in a college 200 level-class) In the second example, are you using "population parameter" (where you drew the line on the 5) interchangeably with mean or median? Is population parameter, in this example, used as a general term to describe a center point in the population distribution that's not a mean or median? If so, what is a population parameter in the example I'm asking so I have a better understanding of why I should care that the sample distribution is a bias/unbiased estimator in regards to the "5" Comment from : Ryan Gaines

Unbiased due to the variety of times he calculated the resultbrStatistic B Comment from : Divis Mean

That first distribution looks pretty flat, you'd expect a more normal distribution Comment from : bigcat56308
