What is regression analysis?
Regression analysis is a common method of statistical inference that attempts to determine the strength and character of the relationship (or correlation) between one dependent variable (usually denoted by Y) and a series of other variables (known as independent variables).
What is the theme of statistics?
One of the recurring themes of statistics is that we are able to say something about a large group based on the study of a relatively small portion of that group. The group as a whole is known as the population. The portion of the group that we study is the sample .
What is the purpose of descriptive statistics?
One way to analyze data is called descriptive statistics. Here the goal is to calculate quantities that describe our data. Numbers called the mean, median and mode are all used to indicate the average or center of the data. The range and standard deviation are used to say how spread out the data is.
Why is probability important in statistics?
It also gives us a way to talk about randomness. This is key to statistics because the typical sample needs to be randomly selected from the population. Probability was first studied in the 1700s by mathematicians such as Pascal and Fermat.
What is the mathematical science that helps us to deal with this information overload?
To make sense of all of this information, certain tools and ways of thinking are necessary. The mathematical science called statistics is what helps us to deal with this information overload. Statistics is the study of numerical information, called data. Statisticians acquire, organize, and analyze data.
When was probability first studied?
Probability was first studied in the 1700s by mathematicians such as Pascal and Fermat. The 1700s also marked the beginning of statistics. Statistics continued to grow from its probability roots and really took off in the 1800s.
When we begin with a sample and then try to infer something about the population, we are using inferential
When we begin with a sample and then try to infer something about the population, we are using inferential statistics. In working with this area of statistics, the topic of hypothesis testing arises. Here we see the scientific nature of the subject of statistics, as we state a hypothesis, then use statistical tools with our sample to determine the likelihood that we need to reject the hypothesis or not. This explanation is really just scratching the surface of this very useful part of statistics.
Is statistics a branch of mathematics?
Although some think of statistics as a branch of mathematics, it is better to think of it as a discipline that is founded upon mathematics. Specifically, statistics is built up from the field of mathematics known as probability. Probability gives us a way to determine how likely an event is to occur. It also gives us a way to talk about randomness. This is key to statistics because the typical sample needs to be randomly selected from the population.
What is the science of measuring the social organism regarded as a whole in all its manifestations?

Is physics a complete science?
But it is not a complete science such as Physics and Chemistry. Because in these all the causes are kept under control and the observations and results are found similar. But such is not the case with statistics, because observations are made and results are found, but in the mean time situations change so result also change.
What are the characteristics of statistics?
The important characteristics of Statistics are as follows: 1 Statistics are numerically expressed. 2 It has an aggregate of facts 3 Data are collected in systematic order 4 It should be comparable to each other 5 Data are collected for a planned purpose
What is the purpose of statistics?
The main purpose of using statistics is to plan the collected data in terms of the experimental designs and statistical surveys. Statistics is considered as a mathematical science that works with the numerical data. In short, statistics is a crucial process, which helps to make the decision based on the data. Statistics for Class 10.
What are the two main branches of statistics?
Types of Statistics. The two main branches of statistics are: Descriptive Statistics. Inferential Statistics. Descriptive Statistics – Through graphs or tables or numerical calculations, descriptive statistics uses the data to provide the descriptions of the population.
Why is statistics important?
Statistics helps in gathering information about the appropriate quantitative data. It depicts the complex data in the graphical form, tabular form and in diagrammatic representation, to understand it easily. It provides the exact description and better understanding.
What are the courses in statistics?
In addition to the calculus sequence, there are other courses in mathematics that are important to statistics. They include the following courses: 1 Linear Algebra: Linear algebra deals with the solutions to equations that are linear, meaning that the highest power of the variables is the first power. Although the equation 2 x + 3 = 7 is a linear equation, the equations that are of most interest in linear algebra involve several variables. The topic of matrices is developed to solve these equations. Matrices become an important tool to store data in statistics and other disciplines. Linear algebra also directly pertains to the area of regression in statistics. 2 Probability: Probability is foundational for much of statistics. It gives us a way to quantify chance events. Starting with set theory to define basic probability, the course will move on to more advanced topics in probability such as conditional probability and Bayes theorem. Examples of other topics may include discrete and continuous random variables, moments, probability distributions, the law of large numbers and the central limit theorem. 3 Real Analysis: This course is a careful study of the real number system. In addition to this, the concepts in calculus such as limit and continuity are developed rigorously. Many times theorems in calculus are stated without proof. In analysis, the goal is to prove these theorems using deductive logic. Learning proof strategies is important to develop clear thinking.
Why is calculus important in statistics?

Similarly, "own" children in a subfamily are sons and daughters of the married couple or parent in the subfamily. (All children shown as members of related subfamilies are own children of the person (s) maintaining the subfamily.)
When was the single educational attainment question introduced?
The single educational attainment question now in use was introduced in the CPS beginning January 1992, and is similar to that used in the 1990 Decennial Census of Population and Housing. Consequently, data on educational attainment from the 1992 CPS are not directly comparable to CPS data from earlier years.
Overview
Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied. Populations can be diverse groups of people or objects such as "all people living in a country" or "every atom com…
Introduction
Statistics is a mathematical body of science that pertains to the collection, analysis, interpretation or explanation, and presentation of data, or as a branch of mathematics. Some consider statistics to be a distinct mathematical science rather than a branch of mathematics. While many scientific investigations make use of data, statistics is concerned with the use of data in the context of uncertainty and decision making in the face of uncertainty.
History
The early writings on statistical inference date back to Arab mathematicians and cryptographers, during the Islamic Golden Age between the 8th and 13th centuries. Al-Khalil (717–786) wrote the Book of Cryptographic Messages, which contains the first use of permutations and combinations, to list all possible Arabic words with and without vowels. In his book, Manuscript on Decipherin…
Statistical data
When full census data cannot be collected, statisticians collect sample data by developing specific experiment designs and survey samples. Statistics itself also provides tools for prediction and forecasting through statistical models.
To use a sample as a guide to an entire population, it is important that it truly represents the overall population. Representative sampling assures that inferences and conclusions can safely …
Methods
A descriptive statistic (in the count noun sense) is a summary statistic that quantitatively describes or summarizes features of a collection of information, while descriptive statistics in the mass noun sense is the process of using and analyzing those statistics. Descriptive statistics is distinguished from inferential statistics (or inductive statistics), in that descriptive statistics aims to summari…
Misuse
Misuse of statistics can produce subtle but serious errors in description and interpretation—subtle in the sense that even experienced professionals make such errors, and serious in the sense that they can lead to devastating decision errors. For instance, social policy, medical practice, and the reliability of structures like bridges all rely on the proper use of statistics.
Applications
Applied statistics, sometimes referred to as Statistical science, comprises descriptive statistics and the application of inferential statistics. Theoretical statistics concerns the logical arguments underlying justification of approaches to statistical inference, as well as encompassing mathematical statistics. Mathematical statistics includes not only the manipulation of probability distrib…

Examples of Statistics
- The root of statistics is driven by variables. A variable is a data set that can be counted that marks a characteristic or attribute of an item. For example, a car can have variables such as make, model, year, mileage, color, or condition. By combining the variables across a set of data (i.e. the colors of all cars in a given parking lot), statistics allows us to better understand trends and outc…
Populations and Samples
- After analyzing variables and outcomes as part of statistics, there are several resulting levels of measurement. Statistics can quantify outcomes in these different ways: 1. Nominal Level Measurement. There is no numerical or quantitative value, and qualities are not ranked. Instead, nominal level measurements are simply labels or categories assigned to other variables. It's easi…
Acquiring Data
- To gather statistical information, it would often not be possible to gather data from every data point within a population. Instead, statistics relies on different sampling techniques to create a representative subset of the population that is easier to analyze.
