The distribution is said to be left-skewed, left-tailed, or skewed to the left, despite the fact that the curve itself appears to be skewed or leaning to the right; left instead refers to the left tail being drawn out and, often, the mean being skewed to the left of a typical center of the data.

Since salaries tend to be skewed to the right, the offer will most likely reflect the mode or median. You simply need to ask to which “average” the offer refers and what is the mean of this average since the mean would be the highest of the three values.

Similarly, a distribution that is skewed to the left (Indeed, if you know a distribution is normal, then knowing its mean and standard deviation tells you exactly which normal distribution you have.) But for skewed distributions, the standard deviation gives no information on the asymmetry. It is better to use the first and third quartiles 4, since these will give some sense of the

The normal distribution is completely determined by the parameters µ and σ. It turns out that µ is the mean of the normal distribution and σ is the standard deviation. We use the abbreviation N ( µ, σ ) to refer to a normal distribution with mean µ and standard deviation σ .
