A list of StatCrunch directions is provided at the bottom of this text-box.
Recall the following example: The average gestation period, or time of pregnancy, of an animal is closely related to its longevity—the length of its lifespan. Data on the average gestation period and longevity (in captivity) of 40 different species of animals have been recorded.
For the StatCrunch problem, you will analyze data for 40 species of animals in captivity.
animal: the name of the animal speciesgestation: the average gestation period of the species, in dayslongevity: the average longevity of the species, in years
The explanatory variable is average lifespan (longevity.) The response variable is length of pregnancy (average gestation period.)
In the first question you will produce a scatterplot in StatCrunch (with longevityas the explanatory variable and gestation as the response variable) and then use StatCrunch to calculate the correlation coefficient.
Here is a PDF document with all StatCrunch directions (Links to an external site.).
If you have not done so yet, open the animals data set in the Stats at Cuyamaca College group on StatCrunch (directions - opens in a new tab).
