The IV (Independent Variable) is preformance in school.
The DV (Dependent Variable) is breakfast.
BTW, Hetty, this is Sean, just under a new account.

a survey variables would be one child eats no breakfast how well does he do in school an in general then the next kid eats a good breakfast you compare the two make it all up jimmy eats a balanced breakfast gets a's has all kinds of friends. the kid who does not eat breakfast is a loser you get the picture the variables are the differences and how they affect each kid

the variable is whether or not breakfast is eaten.
The controls are gender, age, socioeconomic status and so forth.
You need a study that uses a large random sample of the population. or a study that follows the same student over a period of time and when he/she eats breakfast or not.

There are 3 variables in any experiment.
Independent: children not eating breakfast
Dependent: children's performance
Control: children eating breakfast

The (basic) variables are as follows:
gender
the age of the child
the grade the child is in
what they eat for breakfast
what time they eat breakfast
the performace requirements that day (test, quiz, lessons, etc)
good luck!!!!!

Yes it does, if they don't eat, they can't concentrate on their studeis, they concentrate on how hungry they are. breakfast means to break the fast from the time they go to bed to the time they get up. yes eating breakfast helps kids better in school. It's hard to concentrate on an empty stomach.

Yes. I learned it in school hetty. If you don't eat, you can't concentrate. Because you'll be concentrated on hunger. Hunger will distract you. If you eat, you'll be more happy and energized so you can do better in school. There.
