If the personal opinion of a scientist affects the way that the experimental results are reported, that is called bias.
Explanation:
-An experimenter bias, is a process where the scientists performing the research influence the results, in order to portray a certain outcome.
-Bias is among the factors that makes a qualitative research much more dependent upon experience and judgment than quantitative research.
-Bias in a research may arise from experimental errors and failure to consider all the possible variables and also when the researchers select the subjects that are more likely to generate the desired results.
