An Example of How to Write a Hypothesis
The 'learned system' or 'learning' is the product of formal instructionand it comprises a conscious process which results in conscious knowledge'about' the language, for example knowledge of grammar rules. Accordingto Krashen 'learning' is less important than 'acquisition'. .

The Monitor hypothesis explains the relationship betweenacquisition and learning and defines the influence of the latter on the former. The monitoring function is the practical result of the learned grammar. According to Krashen, the acquisition system is the utterance initiator, while the learning system performs the role of the 'monitor' or the 'editor'. The 'monitor' acts in a planning, editing and correcting function when three specific conditions are met: that is, the second language learner has sufficient time at his/her disposal, he/she focuses on form or thinks about correctness, and he/she knows the rule.
The Happiness Hypothesis - Jonathan Haidt
Let's say you decide to eat greasy food every day for a week and record the effect on your face. Then, as a control, for the next week you'll avoid greasy food and see what happens. Now, this is not a very because it does not take into account other factors, such as hormone levels, stress, sun exposure, exercise or any number of other variables which might conceivably affect your skin. The problem is that you cannot assign cause to your effect. If you eat french fries for a week and suffer a breakout, can you definitely say it was the grease in the food that caused it? Maybe it was the salt. Maybe it was the potato. Maybe it was unrelated to diet.You can't prove your hypothesis. It's much easier to disprove a hypothesis. So, let's restate the hypothesis to make it easy to evaluate the data.
