What happens to the correlation when a high outlier is removed from a data set?
The answer will depend on whether the outlier is determined on the basis of one variable or both variables.
What is regression analysis and inferential analysis?
Regression AnalysisIt is a collection of statistical techniques to understand the relationship among several independent variables and one or more dependent random variables.Inferential AnalysisIt is collection of mathematical techniques to make prediction about unseen large data sets on the basis of a study of available small samples of that data.Regression analysis is a specific way of performing inferential analysis.
Why is René Descartes considered the father of analytical geometry?
Because René Descartes developed the Cartesian coordinate system, this system allows geometric shapes to be expressed in algebraic equations. Descartes' works is still today the basis in analytic geometry.
3 important principles in making generalizations about populations on the basis of samples?
1. To describe the important characteristics of the scientific approach and show how it promotes critical thinking. 2. To demonstrate the limits of everyday intuition and common sense. 3. To show how psychologists use three basic research methods: description, correlation, and experimentation. 4. To explain how psychologists use statistics in their research. are the most important principles in making generalizations about populations on the basis of samples.

What is the philosophy behind African socialism?
"The basis of socialism is a belief in oneness of man and the common historical destiny of mankind. Its basis... is human equality"
Why is Euclid named the father of geometry?
He is the first person to set out geometry on a systematic basis starting from a small number of axioms. He was also responsible for developing the principles of geometric proof.

Is there any scientific basis for superstitions?
While there are certainly historical, anthropological and cultural reasons behind most superstitions, they are called superstitions because of the very fact that they have no basis in Science.
Requirements of regression analysis in statistics?
You may get more ideas from wikipedia under regression analysis. You can do a regression analysis with as little as 2 x,y points- but is it meaningful? Requirements for valid or meaningful relationships can be subjective. However, in my opinion, if meaningful relationships are to be created using regression analysis, the following are important: a) The independent variable should have values that are independent (no relation exists between them). b) There should be a good rational or experimental basis for identifying the independent variables and the resultant dependent variable. c) Sufficient data should be collected in a controlled environment to identify the relationship. d) The validity of the relationship should easy to identify both visually and by numbers (see "goodness of fit" tests).

Is Pythagoras Muslim?
Pythagoras was a Greek from Samos and he was likely a follower of the Greek pantheon of gods. Many Muslims would later use his geometric proofs as a basis for more complicated math such as trigonometry or algebra, but he was not a Muslim.
Would you get the largest reduction in risk by spreading your portfolio across two stocks?
Your risk is reduced by investing in stocks with low correlation (prices do not move in sync). This is the basis of modern portfolio theory (look it up at investopedia).
