A z score can be placed on a normal distribution curve. It simply shows the position of the raw score in terms of the distance of this score from the mean when you measure it in standard deviation units. In case you get a positive z score, then you know that the value is above the...

Basically, all you are doing with the formula is subtracting the mean from X and then dividing that answer by the standard deviation.Step 4:Find the area using the z-score from step 3. Use thez-table.Not sure how to read a z-table? See the video on thez-table page.Step 6:Go to...

因为normal distribution是可以用方程来表示的,还可以求面积。而面积意味着可以计算分布其中的数值的比例,比例意味着probability的计算。这里又有一个现成的表格,the unit normal table,可以辅助你计算面积或是概率。 The unit normal table lists relationships between z-score locations and proportions in a normal ...
A normal distribution is the bell-shaped frequency distribution curve of a continuous random variable. Visit BYJU’S to learn its formula, curve, table, standard deviation with solved examples.
