    Ответ создан на основе результатов поиска

    Кездейсоқ шаманың дисперсиясы — оның математикалық күтуіне қатысты мәндерінің таралу өлшемі 1.
    Оны есептеу үшін мына формулаларды қолдануға болады:
    • Dx = M(x - Mx)2 2;
    • D[X] = E[X2] - (E[X])2 1;
    • S2 = \frac{1}{n}\sum_{i=1}^{n}(Xi - Xbar)2, мұндағы Xbar = \frac1n\sum_{i = 1}^{n}Xi 1.
