综合得分是有可能得分为负值的。然后把综合得分进行排名就可以比较了。

因子得分是标准化值，最后得分在0周围，这个很正常。

负值说明低于平均水平

Intuitively, factors are latent variables that underly the scores in your observed variables. Usually, the interpretation of each of these factors is based on the content of the original variables so that each factor is interpreted as whatever the attributes with high loadings for this particular factor have in common. Ideally, factor scores would therefore represent the score on the underlying latent variable.

By construction, regression factor scores in SPSS are standardized. A score of 0 on a factor therefore means that the ratings of the importance of the relevant attributes is close to the average for your sample. Similarly, a negative score means that the he ratings of the importance of the relevant attributes is lower than average.

请教您一下，怎么把标准化后的这种值转换成符合实际可用的呢。。我看人家后来得到的数值都是几十。。需要什么步骤呢？灰常感谢
