The correlation coefficient of the data on chick survival vs. Clutch size is –0.93. How would you interpret that correlation coefficient?

Answers

The correlation coefficient of the data on chick survival vs. Clutch size is –0.93. How would you interpret that correlation coefficient?

Answer: The correlation coefficient of the data on chick survival vs. Clutch size is –0.93. It means there is strong downhill (negative) linear relationship between chick survival and clutch size.

Correlation coefficient examines the strength and direction of the linear relationship between two continuous variables. The value of the correlation coefficient lies between -1 and 1.


Answer: There is strong negative correlation between chick survival and Clutch size.

Step-by-step explanation:

Given : The correlation coefficient of the data on chick survival vs. Clutch size is -0.93.

We know that when the correlation coefficient has value close to -1 or belongs to range -0.7 to -1, then we call it as strong correlation coefficient.

Since -0.93 is very close to -1, so it means that there is strong negative correlation between chick survival and Clutch size.

It means if chick survival increases then clutch size decreases or vica versa.
