What is kurtosis?

I will answer your question in a couple of ways. First as a concept: Kurtosis is a measure of whether the data are peaked or flat relative to a normal distribution. That is, data sets with high kurtosis tend to have a distinct peak near the mean, decline rather rapidly, and have heavy tails. Data sets with low kurtosis tend to have a flat top near the mean rather than a sharp peak. A uniform distribution would be the extreme case. Now as a mathematical formula: For univariate data Y1, Y2, ..., YN, the formula for kurtosis is:where is the mean, is the standard deviation, and N is the number of data points.

Are the median and the mean always the same value?

No, not necessarily. They each measure central tendency but in different ways. The mean measures the average of all of the scores while the mean is the middle score. In a normal distribution the median and mean must be equal. In other data sets, they may or may not be equal. For example, the set {0, 1, 2, 3, 5, 7, 10} has a mean of 28/7 = 4 and a median of 3.


What probability draw 2 cards sum is 9?

Assuming a standard deck of 52 cards with aces counting as 1 and all face cards counting as 10, there are: 16 ways of drawing an ace and an 8, 16 ways of drawing a 2 and a 7 16 ways of drawing a 3 and a 6 16 ways of drawing a 4 and a 5, for a total of 64 ways to draw 2 cards whose sum is 9. There are 52!/(50!2!) = 1,326 ways to draw two cards, so the probability is 64/1326 = 0.048, or about 1 in 21.
