What is meant by error and bias?
I haven't been able to confirm the answer yet but here's what I believe: 'error and bias' in research terms questions the validity of the results you have found. If you are asked to relate error and bias to your research, they are asking you to share possible errors with the results and whether or not there could be any bias in the results collected.
One way to ensure less sample bias?
Representative/random
Why is it important to make sure you random sample is random?
It is important to make sure your random sample is random in order to make sure the results are accurate, and to prevent experimenter bias.
What system is used for reducing bias and error in the measurement of data?
Scientific method
What is meant by random behavior?
Not chaotic behavior; a tendency to overcome bias (unpredictable short term)
What is the difference between Sampling error vs sampling bias?
Sampling error leads to random error. Sampling bias leads to systematic error.
Difference between standard error and sampling error?
Standard error is random error, represented by a standard deviation. Sampling error is systematic error, represented by a bias in the mean.
Is random error a form of bias?
No, its not.
Did random error have positive value or negative value?
It must be either, otherwise it is systematic error or bias.
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 difference between random assignment and random sampling?
Random sampling is the sample group of subjects that are selected by chance, without bias. Random assignment is when each subject of the sample has an equal chance of being in either the experimental or control group of an experiment.
What is the difference between skepticism and bias?
Skepticism is uncertainty, while bias is prejudice.
What is the difference between the input bias current and the input offset current?
A: difference in bias current causes the other
Advantages and disadvantages of simple random sampling?
advantages: reduce bias easy of sampling disadvantages: sampling error time consuming
What is bias an experiment?
The bias is the difference between the expected value of a parameter and the true value.
What are the differences between sampling error and sampling bias?
Sampling bias is a known or unknown selection of data to be examined in an audit. There should be no bias if the sample is random. Ex ... look at the first item in the file folder. or examine all files for purchases over $10,000, or examine no files for sales less than $500. Sampling error, is the incorrect selection of files for an audit. Ex ... a random number generator tells you to audit file 1547, but you select 1457. Sampling error is also used to describe the fact that auditing a sample will NOT create the exact same answer as auditing every single file or transaction.
Science what is a sample taken without bias?
The answer is Random Sample
