Chebyshevs Theorem Calculator

Publish date: 2024-06-16
Image to Crop Given a probability P that x is within k standard deviations of the mean, then k is denoted below:
k = √1/(1-P(x - μ < kσ)

Using your input of P(x - μ < kσ) = 0.75, let's plug in and evaluate:
k = √1/(1 - 0.75)
k = √1/0.25
k = √4

k = 2


What is the Answer?
