The difference between respondents and non-respondents has lots of impact on the objective. It is also called participation bias. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">This may happen due to various reasons including some may terminate surveys due to poor survey design and some may drop out on account of asking for confidential info about illegal activity and many more.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example &#8211; A survey asking about video games targeted at people over 50, will likely receive no response. Even the targeted audience is incorrect here.<\/span><\/p>\n<h2><b>Why Surveys and Studies?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">We live in a world with a large population and vast cultures, religions, perceptions, histories, and whatnot. Everyone is quite different from the other being that we can only try to categorize people but we will fail very badly. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">If two people have \u2018x\u2019 similar traits even then the possibility of them liking\/disliking or agreeing\/disagreeing on something is unpredictable. So predicting the market, community or a group of people is next to impossible. What\u2019s the solution then?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Surveys, we take surveys and study them to understand the market or any trend in the world. And that is the reason why \u201cSurveys and Studies\u201d hold a great value in any sector. <\/span><\/p>\n<h2><b>Surveys and NRB (Non-Response Bias)<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Now the question arises, How can NRB(Non Response Bias) affect the study? Whenever a survey is held, there are some options\/choices available for people to choose from. If one does not complete the survey, it creates a report with false data.<\/span><\/p>\n<h3><b>Non-Response Bias Mathematical explanation:<\/b><\/h3>\n<p style=\"padding-left: 80px;\"><span style=\"font-weight: 400;\">Let the number of participants be 4 | =&gt; n=4<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span> <span style=\"font-weight: 400;\">Let the options be:<\/span><\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><span style=\"font-weight: 400;\">Option a<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Option b<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Option c<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Option d<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p style=\"padding-left: 80px;\"><span style=\"font-weight: 400;\"><br \/>\n<\/span> <b><i>Now if every user select unique option,<\/i><\/b><b><i><\/i><\/b><\/p>\n<p style=\"padding-left: 80px;\"><b>Survey Results:<\/b><\/p>\n<p style=\"padding-left: 160px;\"><span style=\"font-weight: 400;\">Option a<\/span> <span style=\"font-weight: 400;\">&#8211;<\/span> <span style=\"font-weight: 400;\">25%<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span> <span style=\"font-weight: 400;\">Option b<\/span> <span style=\"font-weight: 400;\">&#8211;<\/span> <span style=\"font-weight: 400;\">25%<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span> <span style=\"font-weight: 400;\">Option c<\/span> <span style=\"font-weight: 400;\">&#8211;<\/span> <span style=\"font-weight: 400;\">25%<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span> <span style=\"font-weight: 400;\">Option d<\/span> <span style=\"font-weight: 400;\">&#8211;<\/span> <span style=\"font-weight: 400;\">25%<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-359923\" src=\"https:\/\/www.questionpro.com\/blog\/wp-content\/uploads\/2022\/05\/image2-1.png\" alt=\"Non-Response Bias 1\" width=\"466\" height=\"308\"><\/p>\n<p style=\"padding-left: 80px;\"><b><i>Now if one user do not takes the survey,<\/i><\/b><b><i><\/i><\/b><\/p>\n<p style=\"padding-left: 80px;\"><b>Survey Results:<\/b><\/p>\n<p style=\"padding-left: 160px;\"><span style=\"font-weight: 400;\">Option a<\/span> <span style=\"font-weight: 400;\">&#8211;<\/span> <span style=\"font-weight: 400;\">33.33%<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span> <span style=\"font-weight: 400;\">Option b<\/span> <span style=\"font-weight: 400;\">&#8211;<\/span> <span style=\"font-weight: 400;\">33.33%<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span> <span style=\"font-weight: 400;\">Option c<\/span> <span style=\"font-weight: 400;\">&#8211;<\/span> <span style=\"font-weight: 400;\">33.33%<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span> <span style=\"font-weight: 400;\">Option d<\/span> <span style=\"font-weight: 400;\">&#8211;<\/span> <span style=\"font-weight: 400;\">0%<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-359914\" src=\"https:\/\/www.questionpro.com\/blog\/wp-content\/uploads\/2022\/05\/image1.png\" alt=\"Non-Response Bias\" width=\"450\" height=\"321\"><\/p>\n<p style=\"padding-left: 80px;\"><b><i>The percentage of these options change significantly if one of the users skips or does not complete the survey.<\/i><\/b><\/p>\n<p>&nbsp;<\/p>\n<h2><b>Who gets affected by the NRB (Non-Response Bias) :<\/b><\/h2>\n<ul>\n<li><b>Health sector:<\/b><span style=\"font-weight: 400;\"> The health sector suffers a lot due to NRB(Non Response Bias) as they get false or inaccurate data.

They can, however, be reduced by making an effort to prevent them from happening.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The first step to do this is by understanding response bias and non-response bias which may be caused by either the researcher or the respondent. Sometimes, these biases may be unintentional, like in the case of a respondent who forgets to respond to a survey.<\/span><\/p>\n<p style=\"text-align: center;\"><a class=\"square-cta secondary-lined-cta\" href=\"https:\/\/www.questionpro.com\/a\/showEntry.do?sourceRef=blog\"><strong>CREATE FREE ACCOUNT<\/strong><\/a><\/p>\n<p><strong>Authors<\/strong>: Ashish Jangu &amp; Priyansh Datyal<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is Non-Response Bias?
