Answer
Procedural bias occurs when the unfair amount of pressure is applied to complete their response quickly.
Measurement bias occurs when there is systematic or random error occur while taking the reading.
Design bias occur when the research fails to encounter all the aspects of the projects before presenting conclusion.
1) The correct answer is option B.
Balance is miscalibrated hence there will be systematic error which is a type of measurement bias.
2) The correct answer is option A.
Limiting response time for participant is an example of Procedural bias.
3) The correct answer is option A
Here, Jackie has not surveyed the diverse group so it is the case of design bias
the branch of optics that studies interference, diffraction, polarization, and other phenomena for which the ray approximation of geometric optics is not valid.
The answer is D. Krypton (kr)
Well,
A control in an experiment would basically be the "normal" version of your test subjects.
In a drug testing experiment with people, the control group would be the people who don't take the drug.
In an experiment on the effects of salt on potatoes, the control group would be a potato without salt on it.
So in an experiment to measure the effects of gas additives on fuel, the control would be fuel without additives.
