What is sample taken without bias?
When a p-n junction is taken without a bias, it forms a PHOTO VOLTAIC CELL.
One way to ensure less sample bias?
Representative/random
What is the definition of biased sample for math?
A biased sample is a Statistical Sample in which the sample is biased or have more samples of the things that is being influenced.
When you sample with replacement are the trials independent?
They are, if the sampling and replacement processes don't introduce any bias.
What is the difference between reagent blank and sample blank?
Reagent Blank : Take reagent and add deionised water (in place of sample to be tested). Now measure the OD at specific wavelength --> this OD is your reagent blank. Substract this OD from your test result (with sample) to avoid any false +ve effect due to colour of reagents itself.Sample Blank : Take sample and measure the OD without adding reagents --> this OD is your sample blank. Substract this OD from your test result to avoid any false +ve effect due to colour and turbidity of sample itself. As it is the fact that colour and turbidity of each sample would vary from one to another.So now it is clear that Reagent blank is used to avoid bias due to colour of reagents and Sample blank is used to avoid bias due to sample itself.

How do you ensure less sample bias?
The sample should be selected randomly.
What is it called when a sample doesn't represent the population being polled?
Bias
In a scientific opinion polling a random sample is used to avoid?
bias.
One way to ensure less sample bias?
Representative/random
What are the major source of sampling error?
The major source of sampling error is sampling bias. Sampling bias is when the sample or people in the study are selected because they will side with the researcher. It is not random and therefore not an adequate sample.
What is the definition of biased sample for math?
A biased sample is a Statistical Sample in which the sample is biased or have more samples of the things that is being influenced.
