Which one is NOT the reason for sampling errors?

The correct answer is Option (1) → Large sample size

$\text{Sampling errors arise due to variability and selection issues}$

$\text{Faulty selection of sample} \Rightarrow \text{Yes (causes error)}$

$\text{Different estimates by different samples} \Rightarrow \text{Yes}$

$\text{Sample results have variability} \Rightarrow \text{Yes}$

$\text{Large sample size} \Rightarrow \text{Reduces sampling error}$

The correct answer is Large sample size.
