Yes, the 68-95-99.7 values are specific to the normal distribution and do not apply to other distributions.
About all that can be said in general is Chebyshev's inequality:

Hi all,
From this link: 68-95-99.7 rule - Wikipedia, the free encyclopedia, there is the relationship between sigma and stnadard deviation whereby 1-Sigma, 2-Sigma, 3-Sigma is 68-95-99.7 rule.
Can I confirm that this only applies to normal distribution? If so, then can I say that the term 1-Sigma, 2-Sigma or 3-Sigma would not have any meaning in non-normal distribution?
Thank you.

Hi awkard,
Thanks for the reply.
Actually there is someone who told me that this sigma can also be applied to non-normal distribution since it simply stands for area under the curve. However, I feel that this concept is too misleading.
Thanks for clarifying this.
