Which Question Can You Ask Yourself To Determine The Dependent Variable?

To identify the dependent variable ask yourself, “

What is actually being measured in the experiment?

” For example, to test a hypothesis that eating carrots improves vision, the experimenter would manipulate whether or not subjects ate carrots.

Which is true of the independent variable of an experiment?

An independent variable is the variable that

is changed

in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable. … As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded.

What should your hypothesis represent?

Suppose your hypothesis is: “Braking distance grows linearly with speed. … What should your hypothesis represent?

A possible explanation to a problem or observation

. You just studied 36 terms!

What is the independent variable for the tadpole diet experiment?

Woodfrog tadpoles grow larger if fed a meat-based diet. What is the independent variable for the tadpole diet experiment? In the tadpole diet experiment,

it would be sufficient to test only one single pan of tadpoles that were fed lettuce, and only one single pan of tadpoles fed meat.

What is your hypothesis for this experiment?

The hypothesis is

an educated guess as to what will happen during your experiment

. The hypothesis is often written using the words “IF” and “THEN.” For example, “If I do not study, then I will fail the test.” The “if’ and “then” statements reflect your independent and dependent variables.

What is the independent variable in an experiment example?

It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example,

someone’s age might

be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren’t going to change a person’s age.

What is a good hypothesis example?

Here’s an example of a hypothesis: If you increase the duration of light,

(then) corn plants will grow more each day

. The hypothesis establishes two variables, length of light exposure, and the rate of plant growth. An experiment could be designed to test whether the rate of growth depends on the duration of light.

What are the 3 required parts of a hypothesis?

A hypothesis is a prediction you create prior to running an experiment. The common format is: If [cause], then [effect], because [rationale]. In the world of experience optimization, strong hypotheses consist of three distinct parts:

a definition of the problem, a proposed solution, and a result.

Is a hypothesis a prediction?

The only interpretation of the term hypothesis needed in science is that of a causal hypothesis, defined as a proposed explanation (and for typically a puzzling observation). A hypothesis is not a prediction. Rather,

a prediction is derived from a hypothesis

.

Which is a good hypothesis for this tadpole experiment?

The only difference between your control and experimental groups is the type of food the tadpoles receive. Which is a good hypothesis for this tadpole experiment?

Students who consume large amounts of caffeine while studying will have lower exam scores than those who consume less caffeine

.

Which best describes the diet of Pillbugs?

Pill bugs, sometimes also referred to as roly-pollies, primarily consume plant matter that is either decaying or is already dead and decomposed. Their preferred foods are

soft decaying plants like grasses and leaves

, but they may also eat mulch used in landscaping around the house.

Which is an alternate Nonpredictive hypothesis for the tadpole diet experiment?

Which is an alternate, nonpredictive hypothesis for an experiment about tadpole diets?

Tadpole size will differ if groups of tadpoles are fed different diets

. By the end of the experiment half of our sowbugs were on the dry side and half were on the moist side.

What is hypothesis example?

• If I replace the battery in my car, then my car will get better gas mileage.
• If I eat more vegetables, then I will lose weight faster.
• If I add fertilizer to my garden, then my plants will grow faster.
• If I brush my teeth every day, then I will not develop cavities.

How do you write a good hypothesis?

1. State the problem that you are trying to solve. Make sure that the hypothesis clearly defines the topic and the focus of the experiment.
2. Try to write the hypothesis as an if-then statement. …
3. Define the variables.

How do I write a hypothesis?

1. Don’t just choose a topic randomly. Find something that interests you.
2. Keep it clear and to the point.
3. Use your research to guide you.
4. Always clearly define your variables.
5. Write it as an if-then statement. If this, then that is the expected outcome.
