Short answer

The condition which is required to apply Empirical rule is that data set should be with symmetric distribution.

Step-by-step solution

Given information

We need to find the condition required for empirical rule.

Explanation

The condition which is required to apply empirical rule is that data set should be with symmetric distributions because the Empirical Rule does not apply to data sets with severely asymmetric distributions.
