Researchers conducted a naturalistic study of children between the ages of 5 and 7 years. The researchers visited classrooms during class party celebrations. As a measure of hyperactivity, they recorded the number of times children left their seats. The researchers found a strong positive correlation between sugary snacks offered at the parties and hyperactivity. Based on these findings, the researchers concluded that sugar causes hyperactivity.

In this case, the hypothesis may be 'sugar does not exhibit an effect on hyperactivity'. A hypothesis is a given explanation about the natural world.

Hypothesis and scientific questions

A hypothesis can be defined as a particular testable explanation about a given question that emerges by observing the natural world.

A hypothesis must be tested (either confirmed or rejected) by using the scientific method.

In this case, the dependent variable (i.e., the variable that is changed during by the independent variable) is hyperactivity.

The independent variable is the variable that isn't changed during the experimental procedure.
