n = नमूना आकार = 30
σ = मानक विचलन = 0.13
सूत्र
नमूना माध्य की मानक त्रुटि = σ/√n
गणना
नमूना माध्य की मानक त्रुटि = 0.13/√30
∴ नमूना माध्य की मानक त्रुटि 0.02 है।
माध्य μX̅ के नमूना वितरण का माध्य = μ
प्रतिस्थापन σX̅2 के साथ नमूने का प्रसरण = σ2/n
प्रतिस्थापन के साथ माध्य का मानक विचलन = σ/√n या S/√n
