How to Plan and Write a Testable Hypothesis - wikiHow
Questions are measureable. This is the most important thing to consider when writing your question. Measureable means using specific words to ensure that you can answer your question. For example, better is not measureable. What is better to Anna might not be better to Paul. Instead of better, use higher, taller, or faster. This is measurable. You can measure "higher" with a ruler. You can measure "faster" with a timer. A good question is measureable.

If you wanted to conduct a study on the life expectancy of Savannians, you would want to examine every single resident of Savannah. This is not practical. Therefore, you would conduct your research using a statistical hypothesis, or a sample of the Savannian population.
The American Heritage Dictionary defines a as, "a tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation." This means a hypothesis is the stepping stone to a soon-to-be proven theory. For a hypothesis to be considered a scientific hypothesis, it must be proven through the scientific method. Like anything else in life, there are many paths to take to get to the same ending. Let's take a look at the different types of hypotheses that can be employed when seeking to prove a new theory.
What is Hypothesis? - A Knowledge Archive
Do some research before deciding on your hypothesis. Use the libraries and the Internet to find information. Once you have some background knowledge on your topic, consider emailing or writing to a scientist who specializes in the field you've chosen. It might help to shed some light on your experiment.
Hypothesis | Definition of Hypothesis by Merriam …
Scientists can really change the world with their hypotheses and findings. In an effort to improve the world we live in, all it takes is an initial hypothesis that is well-stated, founded in truth, and can withstand extensive research and experimentation. Seek out your independent and dependent variables and go on out here and make this world a better place. Good luck!

Generally, when comparing or contrasting groups (samples), the null hypothesis is that the difference between means (averages) = 0. For categorical data shown on a contingency table, the null hypothesis is that any differences between the observed frequencies (counts in categories) and expected frequencies are due to chance.
Hypothesis – The Internet, peer reviewed.
The (or hypotheses -- there may be more than one) is our working hypothesis -- our prediction, or what we expect to happen. It is also called the - because it is an alternative to the null hypothesis. Technically, the claim of the research hypothesis is that with respect to the outcome variable, our samples are from different populations (remember that refers to the group from which the sample is drawn). If we predict that math tutoring results in better performance, than we are predicting that after the treatment (tutoring), the treated sample truly is different from the untreated one (and therefore, from a different population).
Most testing is ineffective - Hypothesis
When we pose a research question, we want to know whether the outcome is due to the treatment (independent variable) or due to chance (in which case our treatment is probably not effective). For example, the claim that tutoring improves math performance generally does not predict exactly how much improvement. Each level of improvement has a different probability associated with it, and it would take a long time and a great deal of effort to specify the probability of each of the possible outcomes that would support our research hypothesis.
