Statistics : Computer Oriented Statistical Methods

Description

This Lecture  is an introduction to the Course: #Computer-Oriented-Statistical-Methods

Statistics is the branch of mathetics that deals with the collection, organization, analysis, interpretation, and presentation of data.

#Statistics deals with every aspect of data, including the planning of data collection in terms of the design of #surveys and experiments Statistical methods are

1. Mathematical formulas,

2. models and

3. techniques that are used in statistical analysis of raw research data.

The application of statistical methods extracts information from research data and provides different ways to assess the robustness of research outputs.

2. #Mean

3. #Standard Deviation

4. #Probability

5. #Expectation

6. #Regression

7. #Correlation

Computer Oriented Statistical Methods

We use the Computer Software and Programming language to perform the Statistical method on data.

Benefits of Computer in Statistics Computer help in data #collection, #organization, #analysis, i#nterpretation and #presentation.

Computers are very efficient and fast.

Computer help in making the data more informative.

It is easy to share the information Data correction is very easy
