There are many kinds of pop music, such as country music, R & B music, rock music, etc., but I like movie music best because it's easy to learn, and this kind of music is usually about our life, for example, a new world. These movies are very popular among people, and these movies are watched over and over for many years 。 This is also a good way to learn English, so do you know my favorite music is movie music? Do you know my favorite music is Jay's music? You can ask me, "why my favorite music is Jay's music, because Jay's music is unique, his music is very good, his music is very special. He has made six albums since his new album was called Chopin in November.
Because Jay Chou likes Chopin very much, the name of his new album is Chopin in November. His music is all Chopin's of his family. I tell you, my favorite music is Jay's.
Statistics has two distinct influences on the early development of statistical methods: one is the mother who is committed to keeping the orderly records of government units (the state and statistics come from the same social status); the other is the father of gentleman gambling, who relies on mathematics to improve his skills. The influence of mother on his offspring is shown in counting, measuring, describing, tabulating, sorting and people Census, all of which leads to modern descriptive statistics, from father's influence to modern inferential statistics, which is based on the theory of squareyon probability descriptive statistics, including tabulation, description and description of data sets. These data can be quantitative, such as the measurement of height, intelce or grade variables.
These variables have potential continuous characteristics, or the data can represent qualitative variables, such as , University, major or personality type. A large number of data usually have to go through a process of summary or induction before being understood. Descriptive statistics is a tool to describe, summarize or simplify to comprehensible form.
In other cases, the attribute of large amounts of data is a formal solution to another kind of problem, which brings great difficulties to the independent human brain. Such questions often include trying to use observational samples to predict, for example, a school director who wants to determine the proportion of children who come to school without breakfast in a large school system, who are vaccinated against the flu, or other people who have little knowledge of statistics, the inspector knows that it is not necessary and sufficient to question each child: therefore, from one In a sample with only a few children, the proportion of the whole region can be estimated quite accurately. The purpose of inferential statistics is to predict or estimate the characteristics of a group based on the understanding of the characteristics of only "state" samples.
The early development of statistical methods has two distinct influences: one is the mother who is committed to keeping the orderly records of government units (the country and statistics come from the same Latin root); the other is the gentlemanly gambling father, who relies on mathematics to improve his odds and chances. The influence of the game mother on his offspring, statistics, is represented by counting, measuring, describing and controlling Table, sort and census. All of these lead to modern descriptive statistics, from father's influence to modern inferential statistics, which is completely based on probability theory descriptive collection includes tabulation, description and descriptive data collection.
These data can be quantitative, such as the measurement of height, intelce or grade level. These variables have potential continuous characteristics, or the data may represent qualitative variables, A large number of data, such as gender, university major or personality type, usually have to go through a process of summarization or simplification before being understood. Descriptive statistics is a tool to describe, summarize or simplify to comprehensible form.
Inferential statistics is a way to solve another type of problem, which is characterized by an attempt to use observational samples to make predictions. For example, a school administrator wants to determine the proportion of children who have been vaccinated against influenza among the children who come to school without breakfast in a large school system, or, whatever it is, as long as there is a little statistical knowledge, regulators will know It is unnecessary and inefficient to ask questions to every child. Therefore, the purpose of inferential statistics is to predict or estimate the characteristic population sample of a group based on the understanding of population characteristics.
