A researcher can introduce bias in data analysis by analyzing data in a way which gives preference to the conclusions in favor of research hypothesis. There are various opportunities by which bias can be introduced during data analysis, such as by fabricating, abusing or manipulating the data. Some examples are: 1 reporting non-existing data from experiments which were never done (data fabrication); 2 eliminating data which do not support your hypothesis (outliers, or even whole subgroups); 3 using inappropriate statistical tests to test your data; 4 performing multiple testing (“fishing for P”) by pair-wise comparisons (4), testing multiple endpoints and performing secondary or subgroup analyses, which were not part of the original plan in order “to find” statistically significant difference regardless to hypothesis.

Why is sampling important in research?

Is a case control study biased?

A research would then be biased and it would not allow generalization of conclusions to the rest of the population.
