The value. The value is a descriptor of how far from normality it is. The critical ratio is used to get the p-value, which depends on the sample. So for a larger sample, the same degreed of skew (and hence the same problem) will have a larger critical ratio (which makes it seem like a worse problem.)
if you want to know about normality, skew is a VERY poor choice
Kolmogorov – Smirnov, avaialble in most stats packages is much better, or try eyeballing a normal percentile plot, also avialble in eg SPSS.
or just produce a simple box & whiskers diagram. if its non-normal and skewed then the 75% and 25% will not be equal distance from median, also 90% and 10%. if it is high kurtosis, but symmetric then outliers will show up.
if the reason for non-normality test is to use t-test or ANOVA, then be aware that unequal variance is a wors problem than skew. use unequal variance form of tests
