Academic bias is the bias or perceived bias of scholars allowing their beliefs to shape their research and the scientific community. It can refer to several types of scholastic prejudice, e.g., logocentrism , phonocentrism , [ 1 ] ethnocentrism or the belief that some sciences and disciplines rank higher than others.
Selection bias refers to the problem that, at pre-test, differences between groups exist that may interact with the independent variable and thus be 'responsible' for the observed outcome. Researchers and participants bring to the experiment a myriad of characteristics, some learned and others inherent.
[11] [12] Anchoring bias includes or involves the following: Common source bias, the tendency to combine or compare research studies from the same source, or from sources that use the same methodologies or data. [13] Conservatism bias, the tendency to insufficiently revise one's belief when presented with new evidence. [5] [14] [15]
Even if a study meets the benchmark requirements for and , and is free of bias, there is still a 36% probability that a paper reporting a positive result will be incorrect; if the base probability of a true result is lower, then this will push the PPV lower too. Furthermore, there is strong evidence that the average statistical power of a study ...
In published academic research, publication bias occurs when the outcome of an experiment or research study biases the decision to publish or otherwise distribute it. Publishing only results that show a significant finding disturbs the balance of findings in favor of positive results. [ 1 ]
There are multiple formal definitions of "inherent bias" which depend on the particular field of study. In statistics , the phrase is used in relation to an inability to measure accurately and directly what one would wish to measure, meaning that indirect measurements are used which might be subject to unknown distortions.
Another way to understand independent study is to understand learning from a distance. Learning from a distance is a theory in which the student is at a physical or a mental distance from his or her teacher. The student and the teacher are connected by something such as a worksheet, an essay, or through a website on the internet. [7]
Participation bias or non-response bias is a phenomenon in which the results of studies, polls, etc. become non-representative because the participants disproportionately possess certain traits which affect the outcome. These traits mean the sample is systematically different from the target population, potentially resulting in biased estimates.
