But, each definition could provide different results for your study. Tip: To avoid surveying the wrong people, make sure you clearly define the respondent requirements you need to meet your survey objectives before beginning your project. This step will give your survey results a proper scope. Also remember to be specific in your reports and findings when referring to your population. Using broad terms like poor, rich, large, or small can lead to misinterpretation.
Some surveying methods can make it difficult, or even impossible, for certain people to take part in your study. For example, if you survey commuters you meet walking around on the street , you might not get a representative sample of people who drive or ride bicycles.
Tip: The best way to limit this type of researcher bias is to give all potential respondents an even chance to participate in your survey. In our commuter example, you might be better off sending an online survey to everyone who lives in your town, or asking some local businesses to send your survey out to all their employees. This form of bias is introduced when raw data is transformed into misinterpreted findings.
For example, bias can come into play when a survey creator gets excited about a finding that meets their hypothesis but overlooks the fact that the survey result is only based on a handful of respondents. Make sure that your results have the sample size you need to make conclusive decisions by using our sample size calculator. Tip : Most often, this form of bias is caused by gathering information and then later developing your data analysis strategy. To avoid this type of bias, create a data analysis plan before you write your survey.
Then write questions that you know will work well with the analysis you have in mind. For example, use a multiple choice question if you want to quantify your results. Finally, take note of the different analytical tools available in your survey software beforehand. Here, we will delve into the different types of bias in research that we should strive to eliminate, as well as how we can avoid them.
Bias in research pertains to unfair and prejudiced practices that influence the results of the study. From sampling bias to asking leading questions, unfair practices can seep into different phases of research. Whether or not researchers do it intentionally, bias can negatively affect the outcomes of the study.
It makes the results irrelevant and insignificant. You ought to know how to identify the different kinds of bias researchers and respondents can introduce into the study. In eliminating or, at least, minimizing bias, you can produce research with reliable and valid results that can benefit your business, community, or society in general.
Publishing false claims can do more harm than good to the people and organizations that rely on these studies. Unfortunately, many turn a blind eye to research bias. Sometimes, it could be a lack of resources or time that drives researchers to ignore these unfair practices. Opinion Stage is an interactive content creation platform that can help you minimize bias in research. As it comes with an intuitive survey maker with pre-made yet highly-customizable survey templates , you can write unbiased questions that will produce valid and reliable results.
The survey maker even delivers comprehensive reports on the results and performance of the survey, allowing you to improve the quality of your research.
Human error causes bias in research. Some people may do it intentionally. However, most researchers unknowingly add all kinds of biases into their studies at various phases of the study.
Bias in research, whether quantitative or qualitative, may come in different types. Due to the nature of qualitative data, bias is more likely to occur in this form of research. Not only that, it can exist in all parts of the study. However, qualitative research has more room for creativity and flexibility. Thus, it can produce more insights that one cannot generate from quantitative research. In qualitative research, bias can either be caused by respondents or researchers.
Respondents can add bias to your research by answering questions untruthfully. If they choose answers that are more socially acceptable instead of ones that reflect what they truly think or feel, they unknowingly create bias. Sometimes, respondents also introduce bias when they know the researchers or sponsors of the study. When researchers conduct their study in a manner that influences the outcomes, they commit one of the two main forms of bias in qualitative studies—researcher bias.
Much like respondents, researchers can commit different types of bias in research. Avoiding bias in qualitative studies is challenging. At best, you can eliminate such occurrences in the study to protect the quality of the data you gather and the integrity of the research itself.
Survey participants are often unaware of it, but they tend to introduce bias into research by answering questions untruthfully. Response bias occurs when they feel pressured to answer questions in a more socially acceptable way. Or, they might feel compelled to provide responses that enable researchers to achieve their desired outcomes. Non-response bias is also common, which occurs when response rates are low.
Also dubbed acquiescence bias, friendliness bias occurs when respondents simply tend to agree with the ideas that they are presented within the survey. They may even tend to give more positive ratings or feedback. Sometimes, this happens when participants perceive the brand or researchers as professionals or authoritative figures.
Their acquiescent personalities may enable them to introduce such biases to the research. There are also instances where friendliness bias occurs because of the length of the survey itself. This occurs when people give responses which they think are more socially acceptable. Respondents may provide inaccurate answers just to put themselves in the best possible light.
You can prevent this from happening by choosing your words carefully. Make respondents feel that there is no right answer and that any answer is acceptable. In this article, we define what researcher bias is, describe the different types and provide some key steps for how to avoid it during an examination process.
Researcher bias is a situation that can form when a researcher's perspective influences the results of a study claiming an objective point of view. It can develop during every step of a research process, including the initial planning stage, theory development, data collection and analysis. When researcher bias occurs, a study's results can show a subjective point of view, which can affect how other professionals use its data to market products, create internal policies and engage with clients.
Researchers can introduce bias into studies in varied ways, so they often use multiple tactics throughout a process to reduce this possibility. Here are some types of research biases that can affect a study and ways to avoid them:.
Design and selection bias can occur in the initial planning stage of a study when a researcher chooses data collection and sampling methods that omit key information. If they only include some relevant demographics, their results may only be partially accurate. For example, if a researcher studying the quality of a college textbook only sent survey materials to public universities, they may show an unintentional bias toward one type of student.
By also sending the survey to students from private universities and community colleges, however, they can reduce the overall possibility of including bias in a design plan.

It typically involves instruments a researcher uses or time given to participants to complete a step. Consider an example of a researcher who gave study participants 10 minutes to complete a questionnaire and only offered pencils as a writing implement.
If they only analyze the questionnaire data based on content, they may show bias in the results. By including details about the environment and procedure in your data analysis, you may be able to better avoid procedural bias.
Order effects bias can happen when the sequence order of a researcher's questions influences an interviewee's answers. This type of bias often occurs if a specific question provides context for another, causing the responder to adjust their answer. For example, if a researcher created an interview question about the features of one product followed by a question about the same features in another product, the responder might compare the two items instead of forming separate assessments.
To avoid the possibility of bias in this situation, you can set questions in a randomized order, then have colleagues take the survey in an unofficial capacity to test its effectiveness.
A leading questions bias can take place when a researcher frames a question to elicit a specific answer or respond with a certain emotion. When the researcher writes a question using their own assumptions about the topic, a responder's answer may reflect that assumption more than their own perspective.
For example, consider the interview question, "How did you enjoy using this product? You can reduce this possibility by writing clear, neutral statements in your questions. The halo effect bias can occur when a researcher perceives one response as an interviewee's overall perspective on a topic. For instance, if a researcher recalls more information about an interviewee's enthusiasm for a product, they may minimize other parts of their response in their interpretations, which might show some bias toward only positive feedback in their interpretations.
To avoid bias in this situation, you can take notes about the nuances of an interviewee's responses and remain conscious of the halo effect bias during the process.
Confirmation bias can happen when a researcher's belief system informs their protocols for data collection or analysis.
If you narrow your focus to only one hypothesis, you may unknowingly remember more information that supports it.
Consider an example of two interviewees who shared different perspectives on the same product. If a researcher focussed more on the answer that aligns with their own point of view, the resulting analysis might show some bias. To avoid involving a confirmation bias, you can develop standards for interpreting data that incorporate an awareness of alternative hypotheses and perspectives.
Cultural bias occurs when a researcher prioritizes the values and standards of their own culture while assessing people from a different community. People sometimes use perspectives from their own community to inform their actions, but the research process often requires learning that people can have different perceptions of the same situation. For example, if a researcher interpreted an interviewee's response to a question about daily product usage according to their own standard, the study's results may show bias.
