I did a survey which asked respondents how satisfied they are in their current (romantic) relationship on a 1=10 point scale (where 10="very satisfied). While there was some variation, not surprisingly, the results are strongly negatively skewed. That makes sense - most people are probably satisfied with their relationships or they would leave the other person
So you've got yourself the mirror image of one of these: <http://psycnet.apa.org/psycinfo/1983-09462-001> |The insidious L-shaped distribution. |Bradley, James V. |Bulletin of the Psychonomic Society, Vol 20(2), Aug 1982, 85-88. | |L-shaped distributions are probably more prevalent than generally |realized. They are highly conducive to nonrobustness of |normality-assuming statistical tests, and strongly resist |transformation to normality. The thinner the tail of the |distribution, the more unlikely it is that its L-shapedness will be |detected by inspecting a sample drawn from it. Yet, as the tail of an |L-shaped distribution becomes increasingly shallow, its skewness and |kurtosis depart increasingly from their "normal-distribution" values, |and the distribution becomes increasingly conducive to drastic |nonrobustness. Worse, a fairly common type of experimental situation |in psychological research produces shallow-tailed L-shaped |distributions. If you do a search on statistical techniques for "zero-inflated continuous [or semicontinuous] data," you might be able to apply them to your "ten-inflated data." --David Epstein [email protected] --- You are currently subscribed to tips as: [email protected].
