Calculate Z score using these negative and positive Z score tables based on normal bell shaped distribution
you will see that the area that corresponds to the z score 1.09 is 0.3621. Since the results are different, you may be tempted to think that you’re not doing things right or that you’re looking at the wrong table. This isn’t either. The reality is ...

z分位数（z-score）是表示某个数据点与样本均值之间相差的标准差数量，它用于在符合正态分布的情况下标准化不同事件的度量方式 z的计算公式为：(x - μ) / σ 通过将计算出的z-score与速查表中的数据相对应，我们可以确定该数据点在整体分布中所处的位置 例如：李华的托福成绩为86分，假设托福考试的平均分...

具体计算如下：z = (86 - 59.6) / 20 = 1.32 这意味着李华的z分位数为1.32，这表明他的成绩超过了90.66%的考生，这是一个相当出色的成绩。这就是z-score的魔力，它将看似孤立的分数转化为一个易于理解的标准化比例。但z分位数的真正力量在于，当我们的数据符合正态分布时，它为我们提供...

A z-table reveals what percentage of values fall below a certain z-score in a normal distribution. Here’s how to use one and create your own.
Cells within the table represent the area under the standard normal curve to the left of the z-score. For example, to find the area for z = -2.23, look at the row (-2.2) and column (0.03) intersection, as shown in the truncated z-table below. ...
