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 asymmetry in a distribution. In a non-symmetrical distribution, skewness can be calculated using a formula that considers the deviation of each data point from the mean. A positive skewness indicates a longer tail on the right side of the distribution, while a negative skewness indicates a longer tail on the left side.
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.

How do you find the positive critical value of 0.01?
The positive critical value depends on the distribution and then the parameters (if any) which characterise the distribution.

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.

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.

The Poisson distribution. The Poisson distribution. The Poisson distribution. The Poisson distribution.
