Malunga nale khadi
the standard-normal distribution, the probability density at x is equal to the cumulative probability P(X ≤ x) (the area under the curve to the left). The right-tail probability P(X ≥ x) is equal to the equivalent z-score. The standard-normal distribution is the classic symmetric bell curve that describes heights, measurement errors, test scores and countless other natural quantities. Given a value x, a mean μ and a standard deviation σ, this calculator returns the probability density at x, the cumulative probability P(X ≤ x) (the area under the curve to the left), the right-tail probability P(X ≥ x) and the equivalent z-score, and plots the curve. The standard-normal distribution is equal to the standard-normal distribution.Worked example: The standard-normal distribution is the classic symmetric bell curve that describes heights, measurement errors, test scores and countless other natural quantities.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic symmetric bell distribution.Worked example: The standard-normal distribution is the classic
Imibuzo ebuzwa kaningi
Yini ushintsho phakathi kwe-pdf ne-cdf?
Ubukhulu besimo sesimo (pdf) yiphakamo ye-bell curve ku-x; akuyona isimo sesimo sesimo. Ukusabalalisa okuqotho (cdf) yindawo ngaphansi kwe-curve kuze kube yi-x, okunikeza isimo sesimo sexabiso ku-x noma ngaphansi kwayo.
Kungani ingozi yenani elifanele liyi zero?
Ukusabalalisa okuqhubekayo njengento ejwayelekile, noma yisiphi isiphetho esicacile sinomqondo ophansi - amabanga kuphela anengqondo engekho emthethweni. Lokhu kusho ukuthi sicela ubukhulu ku-x kanye nendawo eqoqiwe endaweni ye-P (X = x).
Yini imithetho ye-68-95-99.7?
Ukusabalalisa okujwayelekile, cishe i-68% yamaxabiso akhona ngaphakathi kwe-standard deviation eyodwa ye-mean, i-95% ngaphakathi kwe-2 ne-99.7% ngaphakathi kwe-3. Kuyindlela ekhawulelayo yokucabanga ukuthi ixabiso linjani ngaphandle kokubala indawo efanele.
Ngiyithola kanjani ingozi phakathi kwamaxabiso amabini?
Ngeza inani eliphansi njenge x nenani eliphezulu njenge x₂; i-calculator ibuyisela i-P(x ≤ X ≤ x₂) ngokususa i-cumulative probability engxenyeni ephansi kusuka kuleyo engxenyeni ephezulu.
Yini ushintsho phakathi kokuhlukaniswa okujwayelekile nesimo esijwayelekile?
Isilinganiso esijwayelekile siyisilinganiso sokusabalalisa esijwayelekile esiphakathi kuka-0 nesilinganiso sokungalingani ko-1. Ukushintsha noma yisiphi isilinganiso sibe yiz-z-score isiza isilinganiso esijwayelekile, okuwukuthi indlela le thuluzi elibala ngayo i-probability nganoma iyiphi i-μ ne-σ.
Ingabe idatha yami kufanele ibe ngempela ejwayelekile?
Akukho data ekhona ejwayelekile, kodwa izimpendulo zithembekile uma idatha ifana ne-bell futhi ilingana. Ku-data eqinile noma enzima-i-tailed, i-probability ilinganiselwe kuphela.
