Correlation analysis is a type of statistical analysis used to measure the strength of the relationship between two variables. It is used to determine whether there is a cause-and-effect relationship between two variables or if one of the variables is simply related to the other. It is usually expressed as a correlation coefficient a number between -1 and 1. A positive correlation coefficient means that the variables move in the same direction while a negative correlation coefficient means they move in opposite directions.
Regression analysis is a type of statistical analysis used to predict the value of one variable based on the value of another. This type of analysis is used to determine the relationship between two or more variables and to determine the direction strength and form of the relationship. Regression analysis is useful for predicting future values of the dependent variable given a set of independent variables.

What is correlation analysis?
We consider correlation as a several independent variables.
How is the coefficient of correlation interpreted?
correlation is a difference in statistics
What is the difference between correlation coefficient and chi square?

What is the difference between quantitative analysis and statistics?
statisctics are raw numbers while quantitive analysis is what those numbers repersent.
What is the importance of correlation and regression analysis in business decision making?
Correlation and regression analysis can help business to investigate the determinants of key variables such as their sales. Variations in a companies sales are likely to be related to variation in product prices,consumers,incomes,tastes and preference's multiple regression analysis can be used to investigate the nature of this relationship and correlation analysis can be used to test the goodness of fit. Regression can also be used to estimate the trend in a time series to make forecast
What is the difference between correlation analysis and regression analysis?
In linear correlation analysis, we identify the strength and direction of a linear relation between two random variables. Correlation does not imply causation. Regression analysis takes the analysis one step further, to fit an equation to the data. One or more variables are considered independent variables (x1, x2, ... xn). responsible for the dependent or "response" variable or y variable.
What is the purpose of a correlation analysis?
The purpose of correlation analysis is to check the association between two items. This can be useful in determining accuracy.
What is the purpose of using correlation analysis How might correlation analysis be used in business decisions or in strategy formulation and implementation?
The correlation analysis is use in research to measure and interpret the strength of a logistic relationship between variables.
What are the strengths and weaknesses of correlation analysis?
Strengths:WeaknessesCalculating the strength of a relationship between variables.Cannot assume cause and effect, strong correlation between variables may be misleading.Useful as a pointer for further, more detailedresearch.Lack of correlation may not mean there is no relationship, it could be non-linear.
What is the difference between positve and negative correlation?
Positive correlation has a positive slope and negative correlation has a negative slope.
What is the difference between Interrelation and Correlation?

What is the difference between Multicollinearity and Autocorrelation?
The difference between multicollinearity and auto correlation is that multicollinearity is a linear relationship between 2 or more explanatory variables in a multiple regression while while auto-correlation is a type of correlation between values of a process at different points in time, as a function of the two times or of the time difference.
