Explanation Given: The given points are ( − 1 , 2 ) ( 0 , − 1 ) ( 1 , 1 ) . Concept used: Let us consider that equation of the least square line be y = b + m x . Minimize f ( b , m ) to find the value of b and m . The function f ( b , m ) will be the sum of square of the vertical distance from the given points ( x 2 , y 2 ) , ( x 2 , y 2 ) , ( x 3 , y 3 ) to the line. f ( b , m ) = ( y 1 − ( b + x 1 m ) ) 2 + ( y 2 − ( b + x 2 m ) ) 2 + ( y 3 − ( b + x 3 m ) ) 2 Calculation: Here, the given points are ( − 1 , 2 ) ( 0 , − 1 ) ( 1 , 1 ) . y 1 = 2 , y 2 = − 1 , y 3 = 1 and x 1 = − 1 , x 2 = 0 , x 3 = 1 We have the equation of the line as y = b + m x . f ( b , m ) = ( 2 − ( b − m ) ) 2 + ( − 1 − ( b + 0 ) ) 2 + ( 1 − ( b + m ) ) 2 Differentiate f ( b , m ) partially with respect to b . f b = 2 ( 2 − ( b − m ) ( − 1 ) ) + 2 ( − 1 − ( b ) ( − 1 ) ) + 2 ( 1 − ( b + m ) ( − 1 ) ) f b = − 4 + 2 b − 2 m + 2 + 2 b − 2 + 2 b + 2 m f b = − 4 + 6 b Differentiate f ( b , m ) partially with respect to m

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 p…
