Document Summary
The z score has more spread out value than, z score for wage(standardized) unstandardized, similarities both skewed to the right. The skew and kurtosis are the same: differences they have different means and standard deviations. The unstandardized has a greater maximum and the standardized has a lower minimum: z score for age(standardized) unstandardized, similarities both have no true skew. The mean is smaller than the median in both. The skew and kurtosis are the same in both: differences they have different standard deviations and means. The max in the unstandardized is greater than the standardized. The min is greater for the unstandardized: z score for education (standardized) unstandardized, similarities both have no true skew, but appear to be left skewed. The skew and kurtosis are the same in both: differences the mean is smaller than the median in standardized and the reverse for unstandardized.
