However, the reliability of survey results depends heavily on the quality of the data collected. Bad data, caused by factors like respondent dishonesty, survey fatigue, and technical issues, can skew results, leading to inaccurate conclusions and poor decision-making. This article explores the causes of bad data in online surveys and strategies to mitigate these risks.<\/p>\n<h3 data-start=\"662\" data-end=\"707\">Causes of Bad Data in Online Surveys<\/h3>\n<h4 data-start=\"709\" data-end=\"758\">1.

Poor Sampling and Targeting<\/h4>\n<p data-start=\"2070\" data-end=\"2194\">Collecting data from the wrong audience or an unbalanced sample can also lead to bad data.
