To confirm a hypothesis, we need scientific evidence. In order to get enough evidence to confirm their hypotheses, researchers who want to prove something must conduct their research according to accepted rules and procedures. These rules inform researchers how to choose who will take part in their study, how to collect data and how to analyze the data they collect.
If researchers don't follow these rules, we cannot accept their results as scientific evidence.
These rules are called the scientific method. For more about the scientific method, select AWL word "method" and go to Exercise 6.
Confirmed or Unconfirmed: That is the Question!
In 2004 researchers examined the expectations of people who were trying to find a “perfect” partner through online dating. Their central hypothesis was that online daters have unrealistically optimistic expectations of finding an ideal partner, and that this could lead to unsuitable relationships. The results of this experiment showed that most people who dated online were over-optimistic in their expectations of finding a suitable partner.
