香港HR作业Strategic Human Resources Manager – HR Measurement & Costing

1.a. Why do researchers standardize scores?
b. You know that the mean of a distribution of attitude measures is 33.9, and its standard deviation is 6.8. What is the Z score associated with an attitude score of 42.2?
1。答：为什么研究人员标准化得分？
你知道，态度测量分布的均值为33.9，其标准偏差为6.8。Z得分42.2的态度得分相关的是什么？

Answers for a question: A Z-score quantifies the original score in terms of the number of standard deviations that that score is from the mean of the distribution. Using www.51lunwen.org/humanresource/ standard scores or percentiles, it is also possible to compare scores from different distributions where measurement was based on a different scale. For example, we could compare two scores from two different intelligence tests, even if the intelligence test scores were expressed in different units (eg, one as an intelligence quotient and one as a percent of answers given correctly).

对于一个问题的答案：Z值量化原始评分的标准偏差数的条款，这些分数是从平均分布。使用标准分数或百分位数，也可能是比较分数从不同分布的测量是基于一个不同规模的。例如，我们可以比较来自两个不同的智力测试中两次得分，即使智商测试分数在不同的单位表示（例如，一个智商和一个作为回答正确百分之一）。

Answers for b question: The formula for converting from an original or "raw" score to a Z-score is:
 
Therefore, when the mean of a distribution of attitude measures is 33.9, and its standard deviation is 6.8, then the Z score associated with an attitude score of 42.2 can be calculated as followed:
                            Z= (42.2-33.9)/6.8 = 1.22

25. In estimating the payoffs associated with training, why is it necessary to correct the effect size, d, for the effects of unreliability in the measure of performance?
Answers: Value for job performance can be expressed as:  , where, SDy means the variability of job performance in $, indicating the size of the difference in performance between high and low performers. SDy is effected by the size d, therefore, SDy is also effected by the size d.
