Q. How is an experiment accurate?
A measurement is reliable if you repeat it and get the same or a similar answer over and over again, and an experiment is reliable if it gives the same result when you repeat the entire experiment.
Q. What is a failed experiment called?
Mistake is just another word for a failed experiment. The purpose of experiments is to confirm or deny a hypothesis, or in other words, to learn something.
Q. What part of an experiment causes a change?
The independent variable is the the part of the experiment that the experimenter has direct control over. Changes in the independent variable cause changes in other variables. Experiments are designed so the changes in all but one of the other variables are controlled or kept constant.
Q. What is the one thing you change in an experiment?
The things that are changing in an experiment are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. The independent variable is the one that is changed by the scientist.
Q. Is anything you change in an experiment to see how if affects?
An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.
Q. What does dependent mean?
a person who depends on or needs someone or something for aid, support, favor, etc. a child, spouse, parent, or certain other relative to whom one contributes all or a major amount of necessary financial support: She listed two dependents on her income-tax form.
Q. How does the IRS define a dependent?
A dependent is a person other than the taxpayer or spouse who entitles the taxpayer to claim a dependency exemption. Each dependency exemption decreases income subject to tax by the exemption amount.
Q. Who qualifies as a tax dependent?
The child must be 19 or younger at the end of the tax year and younger than you (and your spouse if you file a joint return). Qualifying children can be up to 24 years old if they’re also full-time students for at least five months of the year, or they can be any age if they’re permanently and totally disabled.
