2. Sample Size: The size of the sample under scrutiny directly affects the margin of error. More extensive sample sizes generally result in smaller margins of error, as they offer a more accurate depiction of the population under examination.

3. Population Variability: The extent of variability within the population also exerts influence on the margin of error. When the population exhibits more diversity, the margin of error tends to expand, as procuring a representative sample becomes more demanding.

Margin of Error = (Critical Value * Standard Error) / Square Root of Sample Size

The critical value is ascertained by the selected confidence level, and the standard error denotes the standard deviation of the sampling distribution.

Range of Estimates: The margin of error aids in delineating a range within which the genuine value is probable to reside. If the margin of error amounts to 3% and the announced value is 50%, then the genuine value could lie anywhere between 47% and 53%.

Confidence Level: A superior confidence level signifies greater certainty in the results but also engenders a larger margin of error. It proves pivotal to achieve a balance between the desired degree of certainty and the requirement for precise estimates.

Practical Implications: When scrutinizing survey results, the margin of error should be considered to gauge the potential impact of any disparities or changes discerned in the data. If the margin of error surpasses the observed difference, it may not hold statistical significance, implying that any conclusions derived from the data should be treated with circumspection.
