Hypothesis Statement will be worked on in class prior to due date Your hypothesis statement will be turned in during science class, reviewed by the teacher and returned.

Identify the dependent and independent variable for each. What effect does studying with music have on student test scores? Listening to music will lead to lower test scores then studying without music.

Listening to music Dependent variable: What effect does light have on plant growth? If plants are watered, then growth height will increase.

## What is a Hypothesis?

The independent variable is that gender male; this is because the amount of violence being measured is male violence.

The males affect the resulting levels of violence.

Men are more likely than women to oppose homosexual marriages. If you are only able to collect data at one point in time, you should conduct what type of study? This is the end of the preview. Sign up to access the rest of the document. What is a Hypothesis?

A hypothesis is a tentative, testable answer to a scientific question. Once a scientist has a scientific question she is interested in, the scientist reads up to find out what is already known on the topic.

Then she uses that information to form a tentative answer to her scientific question.

## Report Abuse

A hypothesis leads to one or more predictions that can be tested by experimenting. Predictions should include both an independent variable the factor you change in an experiment and a dependent variable the factor you observe or measure in an experiment.

A single hypothesis can lead to multiple predictions, but generally, one or two predictions is enough to tackle for a science fair project.

Examples of Hypotheses and Predictions How does the size of a dog affect how much food it eats? Larger animals of the same species expend more energy than smaller animals of the same type. To get the energy their bodies need, the larger animals eat more food.

If I let a pound dog and a pound dog eat as much food as they want, then the pound dog will eat more than the pound dog. Does fertilizer make a plant grow bigger? Plants need many types of nutrients to grow. Fertilizer adds those nutrients to the soil, thus allowing plants to grow more. If I add fertilizer to the soil of some tomato seedlings, but not others, then the seedlings that got fertilizer will grow taller and have more leaves than the non-fertilized ones.The null hypothesis sometimes is called the "no difference" hypothesis.

The null hypothesis is good for experimentation because it's simple to disprove. If you disprove a null hypothesis, that is evidence for a relationship between the .

Writing if then hypothesis worksheet and answers Test Your Hypothesis by Doing an Experiment Analyze Your Data and Draw a Conclusion Communicate Your Results Following the scientific methodwe come up with a question that we want to answer, we do some initial research, and then before we set out to answer the question by performing an experiment and observing what happens, we first clearly identify what we "think" will happen. We make an "educated guess. Writing a Hypothesis for Your Science Fair Project Print What is a Hypothesis?

Research Hypothesis Examples A research hypothesis (H 1) is a type of hypothesis used to design an experiment. This type of hypothesis is often written as an if-then statement because it’s easy to identify the independent and dependent variables and see how one affects the other.

If-then statement. When we previously discussed inductive reasoning we based our reasoning on examples and on data from earlier events. If we negate both the hypothesis and the conclusion we get a inverse statement: if a population do not consist of 50% men then the population do not consist of 50% women.

Although you could state a scientific hypothesis in various ways, most hypothesis are either "If, then" statements or else forms of the null arteensevilla.com null hypothesis sometimes is called the "no difference" hypothesis.

This is an example of how a gradual focusing of research helps to define how to write a hypothesis.

## Formatting a testable hypothesis

The Next Stage - What to Do with the Hypothesis Once you have your hypothesis, the next stage is to design the experiment, allowing a statistical analysis of data, and allowing you to test your hypothesis. After a problem is identified, the scientist would typically conduct some research about the problem and then make a hypothesis about what will happen during his or her experiment.

A better explanation of the purpose of a hypothesis is that a hypothesis is a proposed solution to a problem.
