What impact does regression have on correlation analysis Exp

What impact does regression have on correlation analysis? Explain the two ways correlation can be displayed mathematically. Does one way have an advantage over the other? Please explain your thinking.

Solution

Correlation can be seen as one of the most widely and commonly used statics . A correlation is mainly a single number which explains the extent of relationship between two or more variables.

Rating scale is mainly a controversial middle case. There are some specific meaning of the numbers in rating scales but these meaning are not accurate. They do nto have similar accuracy as of quantities

Correlation Coefficient:-

The result which is obtained from the correlation is termed as correlation coefficient (or \"r\"). and it has a value ranging from -1.0 to +1.0.. Greater the closeness of r with +1 or -1, the more closely the two variables are related.

If r is close to 0, it means there is no relationship between the variables. If r is positive, it means that as one variable gets larger the other gets larger. If r is negative it means that as one gets larger, the other gets smaller (often called an \"inverse\" correlation).
