Use this tag if you question involves the use of an inequality. The inequality may have probabilistic origins or be a purely mathematical inequality. Do not use for measures of inequality, for instance income inequality. For that use the [diversity] tag.

Examples of questions requiring the use of inequalities might be using Markov inequality, Chebyshev, Chernoff, Efron-Stein, Azuma, Kolmogorov, Holder, Jensen, etc.
