A researcher conducted an experiment to study the causes of aggression in children. Half the children were randomly assigned to eat a sugared cereal; the remaining half ate cornflakes with no sugar. The researcher then recorded the number of aggressive acts displayed by the children in a one-hour play period after breakfast. In this experiment: a) the type of cereal is the dependent variable, and the number of aggressive responses is the independent variable. b) the type of cereal is the independent variable, and the number of aggressive responses is the dependent variable. c) breakfast is the independent variable, and the group of children is the dependent variable. d) sugared cereal is the dependent variable and cornflakes is the independent variable.

B.

Explanation:

In the given scenario, types of cereals is independent variable and aggressive responses are dependent variable.

Independent variables can be defined as those variable is a research that can be manipulated or changed by a researcher. An independent variable illustrates the cause and reason of a result.

Whereas, dependent variable can be defined as a variable which is tested or experimented upon.

In the given case, the variable which is being tested is the number of aggressive responses, whereas the variable which is manipulated by the researcher is cereals-- the researcher used sugared cereal and cornflakes without sugar to test the result.

Therefore, the correct option is B.
