If a random variable X has mean value m, and standard deviation s, then

Skewness = E{[(x - m)/s]3}

which can be simplified to

skewness = [E(X3) - 3ms2 - m3]/s3

and for discrete X, E(X3) = sum of x3*Prob(X = x) where the summation is over all possible values of x.

While for continuous X, E(X3) = integral of x3*f(x) where the integral is over the domain of X.

What is skewness how would you find it in a non symmetrical distribution?

Skewness is a measure of the extent to which the probability distribution of a random variable lies more to one side of the mean, as opposed to it being exactly symmetrical.If μ and s are the mean and standard deviation of a random variable X, thenSkew(X) = Expected value of [(X - μ)/s]3


In a perfectly symmetrical bell-shaped normal distribution?

Normal distribution is a perfectly symmetrical bell-shaped normal distribution. The bell curve is used to find the median, mean and mode of a function.


Define skewness and kurtosis?

Skewness is a measure of symmetry, or more precisely, the lack of symmetry. A distribution, or data set, is symmetric if it looks the same to the left and right of the center point. Kurtosis is a measure of whether the data are peaked or flat relative to a normal distribution. See related link. By doing a search on the internet, you can find more examples.

Yes they are. Symmetrical organization means when you can draw a line down the middle of the organism and the two sides look like mirror images. If you draw If you draw a line down the middle of an octopus you would find two sides with equal parts. Sponges and some coral are not symmetrical tho.

What are some applications of normal distribution in your daily life?

Following are some applications:- 1)Computing grades from test scores by using the bell curve to find the average. 2)Same applies to any other normally distrubuted quantity like height,weight etc. • The normal distribution is a distribution that is centered around an average value with an even spread in both directions (standard deviation). • This makes the distribution symmetrical! • This symmetry causes the mean, median, and mode to be the exact same value. • Symmetry will come in handy when calculating probabilities.

What are some symmetrical animals?

Technically seen, symmetrical animals do not exist. If you take an image of an animal/face/organism, and mirror it with Photoshop on the supposed line of symmetry, you will find that the end result, no matter how well edited, will look non-natural. To be symmetrical to a half, the genes of the other half have to be exactly the opposite. There are no known scientific cases where "inverse" genes on one half have been found, so, in short, the answer to your question is: There are no "symmetrical animals.
