Q&A for How to Write a Hypothesis

You have to identify the independent and the dependent variables of the experiment, add it to your hypothesis, and that's it, just make sure your hypothesis is specific!

A hypothesis is necessary as it explains what you predict will happen. When you find the results, you can see what actually happened and whether or not your prediction was correct or similar to the results.

A hypothesis is proposed explanation (an educated guess) with evidence to support your theory.

There's not a strict limit, but your project or paper needs to be understandable and easily digestible, so you don't want to overwhelm the reader with too many experiments and proposals. It's best to limit each experiment to between one and four hypotheses, roughly.

A hypothesis is a supposition gathered by reasoning after consideration of the available evidence; it can be tested by obtaining more data, often by experimentation.

Use accurate, informative research to come up with an educated guess for your hypothesis.

Test it by coming up with an experiment to try to answer your hypothesis/question. For example, if you said, "if I made a wide winged airplane, it would go faster than a narrow winged airplane." Then you would build both and see which one went faster.

Yes, if the research applies to the hypothesis. Example: you have done an experiment to test why plants grow the way they grow,and have taken qualitative and quantitative observations. At the end of the experiment you find that your hypothesis was incorrect, so you have create a new one, but you don't have the time to do another experiment for your new hypothesis. Instead of completely redoing the whole thing and praying that there's still time left before the deadline, you can use the notes you already have to come up with a hypothesis that can be proven by the data resulting from the experiment.

If both of the IVs support the result, then simply combine them using a conjunction like "and." For example, you could say, "If [this] and [that] occurs, then [result] will occur." If the two IVs change different DVs, then two separate hypotheses are required.

You could try something like: Literacy rates and tertiary research publications increase with the number of librarians employed in the Nigerian education system.

It can be as long as you want as long as it is clear and simple, as well as including a prediction of your experiment and variables (what's involved).
