4 0

Answer:

2 levels of the independent variable and 0 levels of dependent variable

Explanation:

Levels of independent variable indicate the types of experiment here. Here we have the control experiment and experimental group. The control experiment/group is the group that is not altered and used to measure the experimental group. The control group is the 50 children that took nutritious breakfast while the experimental group is the 50 children that took doughnuts /non nutritious food. If there are more than two types of experiment, the number of experiment types are the number of levels of the independent variable. The dependent variable here has 0 levels
