WebFeb 3, 2024 · Solution. Here we use Chebyshev’s inequality and work backward. We want 50% = 0.50 = 1/2 = 1 – 1/ K2. The goal is to use algebra to solve for K . We see that 1/2 = 1/ K2. Cross multiply and see that 2 = K2. We take the square root of both sides, and since K is a number of standard deviations, we ignore the negative solution to the equation.

WebAug 4, 2024 · Chebyshev’s inequality can be thought of as a special case of a more general inequality involving random variables called Markov’s inequality. Despite being more general, Markov’s inequality is actually a little easier to understand than Chebyshev’s and can also be used to simplify the proof of Chebyshev’s. WebExample: Imagine a dataset with a nonnormal distribution, I need to be able to use Chebyshev's inequality theorem to assign NA values to any data point that falls within a certain lower bound of that distribution. For example, say the lower 5% of that distribution. This distribution is one-tailed with an absolute zero.
