How sensitive to changes in water temperature are coral reefs? To find out, measure the growth of corals in aquariums where the water temperature is controlled at different levels. Growth is measured by weighing the coral before and after the experiment.

(a) What are the explanatory and response variables?
explanatory variable:
response variable:
(b) Are they quantitative or categorical?
The explanatory variable is:
The response variable is:

A quantitative variable is those that can take a range of values. In this case, the temperature may vary across a range of values associated with the survival of coral reefs.

A categorical (also known as qualitative) variable is characterized to present finite states. In this case, the coral reefs can survive or not depending on their responses to changes in the temperature.

Response and explanatory variables are used in experimental procedure ; the explanatory and response variables are :

Measured variable - > Change in weight of coral (quantitative)

Explanatory variable - > Temperature of water. (categorical)

Explanatory variables are independent variables which causes changes to the measured variable.

Measured variable is the variable we intend to measure in an experiment. They are called dependent variables.

Quantitative variables are numerical values, weight is measured as a number. Hence, it is quantitative.

Categorical variables are labels and are used to group objects into classes. They are Non-numeric. Levels of temperature could be (high, medium, low). Hence, temperature is categorical in the experiment.
