Similarly, we can make the sequence positively skewed by adding a value far above the mean, which is probably a positive outlier, e.g. (49, 50, 51, 60), where the mean is 52.5, and the median is 50.5. As mentioned earlier, a unimodal distribution with zero value of skewness does not imply that this distribution is symmetric necessarily.

This does not look random, but it satisfies the definition of random variable. This is useful because it puts deterministic variables and random variables in the same formalism. The discrete uniform distribution, where all elements of a finite set are equally likely. This is the theoretical distribution model for a balanced coin, an unbiased ...
It is customary to transform data logarithmically to fit symmetrical distributions (like the normal and logistic) to data obeying a distribution that is positively skewed (i.e. skew to the right, with mean > mode, and with a right hand tail that is longer than the left hand tail), see lognormal distribution and the loglogistic distribution. A ...
The three teams in the two biggest markets will pay more than 84 percent of the $311.31 million in luxury taxes assessed by Major League Baseball.
I don’t think I’ll realize ’til maybe I retire and look back in a couple years like, Damn, she was good. Because I can see that, but I do it every day. So for me, it’s normal,” Biles added.
Positive and negative skew is something that is hard to remember -- does anyone know some helps to remind here? I usually think about it as "negative skew" => "there are negative values missing" (if the x-axis has lower/negative values on the left and higher/positive values on the right) and vice versa with positive skew.
