what are three ways a scientist can minimize bias in scientific investigations?

Answer;

Three ways that scientist can use to avoid bias are;

- Sampling method

- Using blind study

- Repetition

Explanation;

Sampling method involves the studying of a small quantity of a particular aspect in order to form an opinion about the whole population. To avoid bias its important to obtain samples that are appropriate and that would cover the entire participants studied.

-Repetition involves repeating a particular experiment several times in order to ensure that one gets the same results that is ensure accuracy of the results.

-Blind study involves an experiment in which the control and the variable groups are conceal from the participants until after the end of the experiment. It is an important factor to avoid bias in scientific research.

Final answer:

Scientists can minimize bias in scientific investigations through randomization, blind studies, and double-blind studies.

Explanation:

There are three ways that scientists can minimize bias in scientific investigations:

1. Randomization: Scientists can assign participants or samples randomly to different groups or conditions to ensure that each group is similar and reduce bias.
2. Blind studies: Scientists can conduct blind studies where participants or researchers are unaware of the group assignments or the purpose of the study to prevent biased behavior or expectations.
3. Double-blind studies: Scientists can also conduct double-blind studies where both the participants and the researchers are unaware of the group assignments to further avoid bias.
