Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
![Which of the following statements about a
system of linear equations (SLE) are TRUE?
You must tick ALL that is TRUE
The solution/s to a SLE represents the
intersection between the geometries (line,
plane etc) described by each SLE.
O Aunique solution to an SLE represents a point
of intersection.
In Gauss-Jordan elimination, when a row of
the row-echelon augmented matrix is all zeros,
the SLE will have a unique solution.
O A SLE that is completely linearly independent
will have infinity solutions.
Real-life and practical problems can give rise
to a SLE, and its solution may present a useful
way to solve the actual problem.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F79e2439f-af18-4d8a-807c-ad7ee47a10fc%2F96340887-2215-4c3b-b38b-bb5f269a7c61%2Fugcfnaa_processed.jpeg&w=3840&q=75)
