What is an example of a directional hypothesis?
The consumption of alcohol will adversely affect performance on a reaction time test.
What is an example non-directional hypothesis?

What is the alternative/experimental hypothesis?
• There will be a significant relationship between two variables.
• One variable will have an effect on another.
• There will be a significant difference between two sets of data.
What does the null hypothesis state?
• There is no significant relationship
• One variable will have no effect on another
• There will be no significant difference between two sets of data
What is an example of a null hypothesis?
The consumption of alcohol will have no effect on a reaction time test.
What is the independent variable?
The variable the researcher manipulates.
What is the dependent variable?
The variable that is measured.
