A negatively skewed distribution is exactly the opposite. With a negatively skewed distribution, most of the scores tend to occur toward the upper end of the scale while increasingly fewer scores occur toward the lower end.

A distribution is skewed if one of its tails is longer than the other. The first distribution shown has a positive skew. ... Negatively skewed distributions do occur, however. Consider this plot of actual test grades on a statistics test where most students did very well but a few did poorly. It has a large negative skew.

A positively skewed distribution is one in which the right (positive) tail of the distribution is the long one (see Figure 6.1). A negatively skewed distribution is one in which the left (negative) tail of the distribution is the long one (see Figure 6.2).

However, because of the negatively skewed distribution, there is now a high probability of making a little money and a low probability of losing a lot. Overall, there is a sixty percent probability of making money and a forty percent probability of losing money.

These distributions are the most common in drug prevention. This type of skewed distribution has most values concentrated on the far left side, the lowest numbers. Fewer cases are concentrated on the higher end. For example, in Jack's program, marijuana use was positively skewed.

This paper compares the mean-variance and the mean-variance-skewness approaches to modelling expected utility. ...

One distinct feature of normal distribution is that mostly all the indications of central tendencies as mean, median and mode are the same in value. Skewed Distribution is asymmetrical in dispersion, as skewness means lopsidedness of frequencies ... Distributions can be either negatively skewed or positively skewed.
