Skew: provides estimation of normal distribution
mean: provides average data value
median: provides dataset middle point
mode: provides most common data
normdist: provides the probability that a dataset exist at or below a considered value.
Standardize: how many standard deviation a given dataset value is away from the mean.
NORMINV: given a probability distribution, what is the value of the considered data

Probability Distribution : Probability Distribution Density function: provide the probability of occurrence of each value in a considered dataset.
Normal Distribution: when a given dataset value can be in different ranges. For example, stock market prices, blood pressure values, etc.
Binomial distribution: Summarizes a group of independent observations by the number of observations in the group that represent one of two outcomes. For example, the proportion of individuals in a random sample who support one of two political candidates
