The following table lists animals that have some of the longest lifespans on earth. Does incubation or gestation time affect an animal’s average lifespan? Some animals have lifespans that average well over 100 years. Animal: Nile, Crocodile, Aldabra Giant Tortoise LakeSturgeon, Galapagos Tortoise, Bowhead Whale Average Lifespan (in Years): 100,152,152,177,211 Incubation/Gestation (in Months): 3, 8, 0.25, 4.7,13.5 Is there a correlation between an animal’s gestation/incubation period and its average lifespan in years? a. Draw the scatterplot for the variables. b. Describe the relationship, if any, shown by the scatterplot. c. Calculate r, the correlation coefficient. How does the correlation coefficient compare to the relationship you saw in the scatterplot?
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 predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
