7 :: What is bayesian?
Bayesians condition on the data actually observed and consider the probability distribution on the hypotheses.
8 :: What is frequentist?
Frequentists condition on a hypothesis of choice and consider the probability distribution on the data, whether observed or not.
9 :: What is likelihood?
The probability of some observed outcomes given a set of parameter values is regarded as the likelihood of the set of parameter values given the observed outcomes.
10 :: What is p-value?
In statistical significance testing, the p-value is the probability of obtaining a test statistic at least as extreme as the one that was actually observed, assuming that the null hypothesis is true. If the p-value is less than 0.05 or 0.01, corresponding respectively to a 5% or 1% chance of rejecting the null hypothesis when it is true
11 :: Give an example of p-value?
Suppose that the experimental results show the coin turning up heads 14 times out of 20 total flips
► null hypothesis (H0): fair coin;
► observation O: 14 heads out of 20 flips; and
► p-value of observation O given H0 = Prob(≥ 14 heads or ≥ 14 tails) = 0.115.
The calculated p-value exceeds 0.05, so the observation is consistent with the null hypothesis - that the observed result of 14 heads out of 20 flips can be ascribed to chance alone - as it falls within the range of what would happen 95% of the time were this in fact the case. In our example, we fail to reject the null hypothesis at the 5% level. Although the coin did not fall evenly, the deviation from expected outcome is small enough to be reported as being "not statistically significant at the 5% level".

12 :: What is sampling?
Sampling is that part of statistical practice concerned with the selection of an unbiased or random subset of individual observations within a population of individuals intended to yield some knowledge about the population of concern.
13 :: What are sampling methods?
There are four sampling methods:
► Simple Random (purely random),
► Systematic( every kth member of population),
► Cluster (population divided into groups or clusters)
► Stratified (divided by exclusive groups or strata, sample from each group) samplings.

► Stratified (divided by exclusive groups or strata, sample from each group) samplings.
14 :: What is mode?
The mode of a data sample is the element that occurs most often in the collection.
x=[1 2 3 3 3 4 4]
mode(x) % return 3, happen most
x=[1 2 3 3 3 4 4]
mode(x) % return 3, happen most
15 :: What is median?
Median is described as the numeric value separating the higher half of a sample, a population, or a probability distribution, from the lower half. The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the middle one
median(x) % return 3.
median(x) % return 3.
16 :: What is quartile?
► first quartile (25th percentile)
► second quartile (50th percentile)
► third quartile (75th percentile)
► kth percentile
► prctile(x, 25) % 25th percentile, return 2.25
► prctile(x, 50) % 50th percentile, return 3, i.e. median
► second quartile (50th percentile)
► third quartile (75th percentile)
► kth percentile
► prctile(x, 25) % 25th percentile, return 2.25
► prctile(x, 50) % 50th percentile, return 3, i.e. median
17 :: What is skewness?
Skewness is a measure of the asymmetry of the data around the sample mean. If skewness is negative, the data are spread out more to the left of the mean than to the right. If skewness is positive, the data are spread out more to the right.
Skewness(x) % return-0.5954
Skewness(x) % return-0.5954
18 :: What is variance?
Describes how far values lie from the mean
var(x) %return 1.1429
var(x) %return 1.1429
19 :: What is kurtosis?
Kurtosis is a measure of how outlier-prone a distribution is.
kurtosis(x) % return2.3594
kurtosis(x) % return2.3594
20 :: What is moment?
Quantitative measure of the shape of a set of points.
moment(x, 2); %return second moment
moment(x, 2); %return second moment
