Question

Which of the following represents a weak positive correlation?a. -0.9b. 0c. +0.2d. +0.9

Answer 1

Answer:

Option C) +0.2

Step-by-step explanation:

We are given the following information in the question:

Correlation:

• Correlation is a technique that help us to find or define a relationship between two variables.

• It is a measure of linear relationship between two quantities.

• A positive correlation means that an increase in one quantity leads to an increase in another quantity

• A negative correlation means with increase in one quantity the other quantity decreases.

• +1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.

• Values between 0 and 0.3 tells about a weak positive linear relationship, values between 0.3 and 0.7 shows a moderate positive correlation and a correlation of 0.7 and 1.0 states a strong positive linear relationship.

• Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.

Thus, a weak positive correlation is given by correlation coefficient of Option C) +0.2
