What does indepedent variable means in science?
The independent variable is the thing that changes with in the experiment to make it an experiment. For example, say I was doing an experiment on something such as "Which sponge brand can absorb the most water?" The independent variable would be the different sponge brands because it would be the thing that changes with in the experiment. Otherwise, if you didn't make an independent variable (the different sponge brands in this case) it wouldn't be an experiment because a sponge of the same brand should hold about the same amount of water as the others.
Is water a variable?
It can be, it depends on your experiment. Independent variables are the variables in an experiment that will not change. If you want to do an experiment that tests how something reacts with water, then starting with a clean controlled water sample for each test would be necessary and an independent variable. Conversely, if you were testing the cleanliness of multiple water sources, then the ideology of clean water would be your dependent variable, which would change upon each testing. WIth your given information I cannot say whether or not you would want water to be either a dependent or an independent variable for your experiment.
Why is the answer repeated trials to in order to increase the validity reliability of your experiament?
Repeated trials can be used to ensure the precision of your results. For example, let's say you are measuring a substance with a scale. You can measure the same amount multiple times to ensure your scale is working properly, and to verify the level of precision the scale is using.Repeated trials can also be used to control for variables. For example, if you are performing a chemical reaction, you could repeat the experiment with varying levels of humidity in the air to see the effect it has on the reaction.Repeated trials by multiple scientists can be used to verify the accuracy of the data reported by another scientist. When a scientist publishes the results of an experiment, other scientists can attempt to reproduce the experiment to verify its legitimacy.
Why is a controlled experiment important to science?
A controlled experiment means that you try to keep all the variables that are involved in the experiment under control apart from the Dependent and the Independent variables to make sure that any results obtained from the experiment have been affected by the independent variable and not some other extraneous variable. It also ensures that the experiment would have high validity. That is, if the experiment has really measured what it was supposed to measure.
What is the independent variable for fingerprint patterns?

Is an independent variable in an experiment?
It's what you change to do your experiment. Say your doing an experiment like my friend Kristen Maxine Rogers is doing: Does air temperature affect how long soap bubbles last, her independent variable would be the different temperatures.

What does conclusiuon mean in a science project?
After doing the experiment or the project, what can you conclude, or what can you say about it or summarize after looking at the data or experiment.

Which variables affect solubility?
Heat will increase solubility of solids but not for gases, pressure will increase solubility of gases, surface area of solids increases solubility, agitation increases solubility. __________________________________________________________ Well it depends on what experiment you are doing but i say it would be between the independent variable and the dependent variable.
What is is an independent variable?
An independent variable is the variable that the scientist changes, and the dependent variables are the variables that the scientist doesn't control. So that would mean that the independent variable is typically the variable being manipulated or changed and the dependent variable is the observed result of the independent variable being manipulated. The independent variable in a science experiment is the variable that you change on purpose. The independent variable is the variable that scientists manipulate in an experiment in order to determine its effect on a dependent variable. For example, if you wanted to see what affected frog deformities, you would set up an experiment where you would have frogs placed in the same environments as each other, except for one variable (independent) that is different. Let's say the control group gets exposed to all the same food, temperature, length of daylight, population density, etc., as the experimental group. The experimental group has the amount of UV exposure varied. The UV exposure (independent variable) would be used to determine its effects on frog deformities (dependent variable).
What does it mean to say that Athens, Greece, is a city-state?
It is an independent city that is also a nation.
What dose it mean to say a projectiles horizontal and vertical velocity are independent or each other?
For practical purposes, it means that you can calculate them independent of one another.
What does mean level of the independent variable?
The mean level of the independent variable refers to the average value or level of the variable across all participants or cases in a study. It represents the central tendency of the independent variable within the sample.

What does fair mean in mathematics?
Fair means unbiased. That is to say, the expected outcome of a set of trials is the same as what would be expected on theoretical grounds.
