I​

Answer 1

Answer:

c.Correlation coefficient is answer

Answer 2

option C is correct

Given

• two regression coefficients
• options as

a)Mean

b) Median

c) Correlation coefficient

d) Mode

To find

• under-root of the product of two regression coefficients

Solution

we are provided with two regression coefficients and are asked to pick out the correct term used to describe a mathematical operation carry doubt with the two regression coefficient.

concept

Regression coefficients

we know that the regression coefficients are used to find out the nature of relationship between two variables.

Taking the root of product of both of the regression coefficient would give correlation coefficient

Correlation coefficient

Correlation Coefficient is used to estimate the degree of relationship between two variables.

Its value ranges from negative one to positive one. Negative one would be perfect negative correlation or in physical sense two variables would be indirectly proportional to each other.

correlation coefficient if equal to zero would mean that there is no relationship between two variables included.

A positive one correlation Coefficient would mean that there is a direct relationship between the variables or in simple sense they are proportional to each other.

option C is correct
