Question

Quizplus · Accepted Answer

The margin of error is a statistical calculation that represents the amount of random sampling error in a survey's results. It indicates the range of values within which the true population value is likely to fall based on a particular confidence level. A larger margin of error indicates more variability in the data, and therefore, less precision in the findings. The other options listed do not pertain specifically to the margin of error. Systematic bias refers to consistent errors in the data collection or analysis processes that skew results in a particular direction. Type I error relates to statistical hypothesis testing and occurs when a null hypothesis is rejected when it is really true. Construct variance refers to differences that arise due to the inherent variability in how survey respondents interpret and respond to questions.
