Question

which of the following statement not correct regarding error in a health research (a )random error due to chance(b) systemic error due to bias c) random error can eliminated by improving study design d) bias distorts the study in one direction​

Answer 1

Answer:

(a )random error due to chance

Answer 2

Answer:

The Correct Option is C

Explanation:

A random error, as the name suggests, is random in nature and very difficult to predict. It occurs because there are a very large number of parameters beyond the control of the experimenter that may interfere with the results of the experiment.Bias is a systematic error that leads to an incorrect estimate of effect or association. Many factors can bias the results of a study such that they cancel out, reduce or amplify a real effect you are trying to describe.Research bias happens when the researcher skews the entire process towards a specific research outcome by introducing a systematic error into the sample data. In other words, it is a process where the researcher influences the systematic investigation to arrive at certain outcomes. Random error, as with most errors in research design is not “error” in the sense of being an obvious mistake. Rather, it is the variability that occurs in data due simply to the natural inconsistency that exists in the world. It cannot be eliminated, but it can be controlled by using larger sample sizes and efficient statistical analysis.
