What effect does a smaller margin of error have on survey results?

A smaller margin of error enhances the accuracy of survey results because it indicates a tighter range within which the true population parameter is likely to fall. When the margin of error is smaller, this suggests that the sample data is closely aligned with the actual values in the larger population. Thus, we can be more confident that the findings from the survey reflect reality.

In practical terms, a smaller margin of error often results from a larger sample size or more precise data collection methods. This allows the survey results to be more reliable, yielding a more accurate representation of the population's opinions or behaviors. As a result, stakeholders can make more informed decisions based on the survey data.
