The people who have higher math ability tend to have lower math anxiety. Student A has high math anxiety is because she/he has a low math ability
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.

Negative correlation:
As increase in one of the variable may decreases the other variable and vice versa.
That is, if the larger values of x are related with the smaller values of y, and the smaller values of x are related with the larger values of y indicates that there is negative linear relationship between the variables x and y.
