▣ Examples

معکوس توزیع تجمعی نرمال استاندارد با احتمال 0.908789 =NORM.S.INV(0.908789)

✦ Tips

  • Given a value for probability, NORM.S.INV seeks that value z such that NORM.S.DIST(z,TRUE) = probability. Thus, precision of NORM.S.INV depends on precision of NORM.S.DIST. NORM.S.INV uses an iterative search technique.

⚠ Common Errors

#VALUE! If probability is nonnumeric, NORMS.INV returns the #VALUE! error value.
Fix: برای probability یک مقدار عددی وارد کنید.
#NUM! If probability <= 0 or if probability >= 1, NORMS.INV returns the #NUM! error value.
Fix: Correct the input value

=CONFIDENCE.NORM() The confidence interval is a range of values. Your sample mean, x, is at the center of this range and the range is x ± CONFIDENCE.NORM. For example, if x is the sample mean of delivery times for products ordered through the mail, x ± CONFIDENCE.NORM is a range of population means. For any population mean, μ0, in this range, the probability of obtaining a sample mean further from μ0 than x is greater than alpha; for any population mean, μ0, not in this range, the probability of obtaining a sample mean further from μ0 than x is less than alpha. In other words, assume that we use x, standard_dev, and size to construct a two-tailed test at significance level alpha of the hypothesis that the population mean is μ0. Then we will not reject that hypothesis if μ0 is in the confidence interval and will reject that hypothesis if μ0 is not in the confidence interval. The confidence interval does not allow us to infer that there is probability 1 – alpha that our next package will take a delivery time that is in the confidence interval. =NORM.INV() Returns the inverse of the normal cumulative distribution for the specified mean and standard deviation. =NORM.S.DIST() NORM.S.DIST returns the standard normal distribution (has a mean of zero and a standard deviation of one). Use this function in place of a table of standard normal curve areas.
