**1. Introduction**

**Statistics** is a comprehensive science through the search, sorting, analysis, description of data and other means to achieve inferring the nature of the measured object, and even predict the future. Statistics uses a lot of professional knowledge of mathematics and other disciplines; its application scope covers almost all areas of social sciences and natural sciences.

Statistics is a branch of applied mathematics, mainly through the use of probability theory to establish mathematical models, the observation system to collect data, conduct quantified analysis and summary, to make inferences and predictions, and provide basis and reference for the relevant decision-making. It is widely used in various disciplines, from the physical and social sciences to the humanities, and even used in the industrial and commercial and government intelligence decisions on. With the accelerated process of digitization, more and more people want to be able to sum up some empirical rules from a large number of data to provide some basis for decision making. Statistics is not just like the words on the surface, but the statistics, but contains the survey, collection, analysis, prediction, etc. The scope of application is very wide. Statistics is divided into three major professional directions: the direction of mathematical statistics, direction of economic statistics and the direction of application of statistics.

**2. Main Terms**

(1) Descriptive statistics: research data collection, processing and description of statistical methods.

(2) Inferential statistics: study how to use the sample data to infer the statistical method of the overall characteristics.

(3) Variable: each observation will have some characteristics of different results.

(4) Categorical variable: the observation results show that the results of a class of variables.

(5) Rank variable: also known as ordinal categorical variables, the observation results show that the variables of some ordered category.

(6) Metric variable: also known as quantitative variables, the observation results showed that the number of variables.

(7) Mean: mean is the average number, sometimes refers to the arithmetic average. This is relative to other ways of calculating the mean, the solution is to add up all the numbers, then the number is divided by the number of, which is measure of central tendency, or a method of average.

(8) Median: that is, the middle of the number, to find the median, the first need from small to large sort, sort after, and then look at the middle of the figure is what.

(9) Mode: the mode is the maximum frequency of the digital data.

**3. Statistical Methods**

1) Ratio measurements: owning zero value and the distance between data is equal to be defined;

2) Interval measurements: the distance between data is equal to be defined but its zero value is not absolute no but self defined (such as intelligence or temperature measurement);

(3) Ordinal measurements: the significance is not shown in its value but in its sequence;

4) Nominal measurements: the measured value does not have the amount significance.

**4. Statistical Techniques**

1) Fisher's Least Significant Difference test

2) Student's t-test

3) Mann-Whitney U

4) Regression analysis

5) Correlation

6) Pearson product-moment correlation coefficient

7) Spearman's rank correlation coefficient

8) Chi-square
