Calculator to find out the z-score of a normal distribution, convert between z-score and probability, and find the probability between 2 z-scores.

Free Standard Normal Distribution Calculator - find the probability of Z using standard normal distribution step-by-step

先看z≤0.54的p值，对照下图，首先看表格最左边那一列，找到0.5，然后，因为0.54的第二位小数是4，所以定位到顶行找到“4”那一列，得到0.7054；同样的方法，我们找到z≤-0.77对应的p …

This p-value calculator helps you to quickly and easily calculate the right-tailed, left-tailed, or two-tailed p-values for a given z-score. It also generates a normal curve and shades in the area …

1. What is P (Z ≥ 1.2 0) Answer: 0.11507. To find out the answer using the above Z-table, we will first look at the corresponding value for the first two digits on the Y axis which is 1.2 and then …

Find P(Z > a). The probability that a standard normal random variable (z) is greater than a given value (a) is easy to find. The table shows the P(Z < a). The P(Z > a) = 1 - P(Z < a). Suppose, …

That is, this table reports P(Z ≤ z) = F(z). For a given value of Z, the table reports what proportion of the distribution lies below that value. For example, F(0) = .5; half the area of the …

P(Z> 1). Sketch the region under the standard normal curve whose area is equal to P(Z> 1). P(Z 6 1) = 0:1587 so P(Z > 1) = 1 0:1587 = 0:8413.

統計學課本最後附錄包括標準常態分配之累積機率值等表格, 以下說明表格之使用與R內建 pnorm, qnorm之應用. 已知標準常態分配 Z 之累積機率值可以直接選取 prob.pdf . pdf 第15頁註明 P(Z …

Use this P to Z calculator to easily convert P-values to Z-scores (standard scores) and see if a result is statistically significant. Supports one-tailed and two-tailed p-values. Detailed …
