The Scientific Method

In any scientific experiment, the scientist controls for the variables within the experiment. If more than one variable influences the experiment, the outcome becomes difficult to determine.

Any factor that can take on different values in an experiment is a scientific variable. For example, in an experiment investigating the effectiveness of a new training program, the variables might be:. Depending on how the researcher operationalizes all the variables in an experiment, the above could be either dependent or independent variables. The independent variable is controlled or changed only by the researcher. In the above example, the researcher may have wanted to see if participating in the training program raised students' scores on a final test. Can you identify the independent variable in this experiment?

Беккеру не хотелось так быстро уходить от алтаря, но когда две тысячи людей ждут причастия, а обслуживают их всего восемь священнослужителей, было бы неприличным медлить с этим священным глотком. Чаша была уже совсем близко, когда Халохот заметил человека в пиджаке и брюках разного цвета. - Estas ya muerto, - тихо прошептал он, двигаясь по центральному проходу. Ты уже мертвец.
