there are two z-tables with negative and positive values. If a z-score calculation yields a negative standardized score refer to the 1st table, when positive used the 2nd table. For George’s example we need to use the 2nd table as his test result corresponds to a positive z-score of ...

Area of Negative Z-Score in a Positive Z-Score TableFirst we have a Standard Normal Distribution Table also known as a Z-Score Table. Then let's assume we only have the positive part of the Z-Score Table. Using only the positive part of the Z-Score Table we find the...
If your z-scores are positive, you’ll use the positive z-score table that shows the values to the right of the mean. And accordingly, a negative table is used for negative z-scores scores appearing to the left of the mean. The type of table you choose will depend on the data derive...
Z score,又称标准分数,为该组数据中各个原始数据点脱离该组数据均值的幅度,幅度以标准差为衡量单位。Z score的计算公式为Z=(x-μ)/σ,其中μ是该组数据的均值,σ是该组数据的标准差,Z是标准分数。 Understanding the Role of Standard Deviation and Z-Scor...
Discover the purpose of z-scores in statistics and learn the formula to find the z-score. Understand what positive and negative z-scores mean. Related to this Question What is the z-score that has the area 0.70 to its right.? From Z score Table: Each value in...
positive or negative. If the score is zero, it indicates that the score is identical to the mean. In other words, it point is average. Positive values represent how far above the mean a point is on the distribution curve. Negative values represent how far below the mean a point is on ...
A positive Z-score can be defined as a specific value that is above the mean value whereas a negative Z-score can be defined as a specific value that is below the mean value. When the Z-score is zero it is equal to the mean value. In our dataset, the mean value is 6 and the ...

Very high or very low (negative) z-scores, associated with very small p-values, are found in the tails of the normal distribution. When you run a feature pattern analysis tool and it yields small p-values and either a very high or a very low z-score, this indicates ...
