Question
Download Solution PDFThere is a very high inverse relationship between measures of ‘Overweight’ and ‘life expectancy’. Which one of the following value of the coefficient of correlation is consistent with the statement ?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFNegative correlation:
- The negative correlation indicates that as the values of one variable increase the values on another variable decrease.
- Similarly, as the values on one variable decrease the values on the other variable increase.
- It means that both the variables move in opposite directions.
- For example, as weight increases, life expectancy decreases due to problems like cholesterol, blood pressure, heart blockages, etc. In statistics, a perfect negative correlation is represented by the value -1.
Since there is a very high inverse relationship, the value of the coefficient of correlation will be - 0.80.
Thus, option 4 is the correct answer.
