Huge sample sizes ≠ much better accuracy

⭕️Contrary to popular belief, increasing sample size beyond a certain point doesn't lead to significantly more accurate results.

⭕️ For large populations, a sample size of 400-1000 can provide reliable results with a 3-5% margin of error at 95% confidence. That's why opinion polls often stick to this range.
