1

What is a hypotheses

A statement of what you believe to be true

2

What is a directional hypothesis

It states the kind of difference between two conditions or two groups of participants higher lower faster slower etc

3

What is a nondirectional hypothesis

It simply states that there is a difference between two conditions or two groups of participants

4

Is this non-directional or directional? Participants gain higher concentrations scores when listening to soft noise than when listening to loud noise

Directional

5

Is this directional or nondirectional? Concentrations scores are different when the task is performed with a soft or a loud noise?

Nondirectional

6

What is a one tailed hypothesis?

It is the same as directional

7

What is a two-tailed hypothesis

It is going in both directions and is the same as a nondirectional hypothesis

8

What is an experimental hypothesis

This is the hypothesis for an experiment

9

What is research hypothesis

This is the hypothesis written for any other kind of study

10

What is alternative hypothesis

This is just another term used the hypothesis it is the alternative to the null hypothesis

11

What is a null hypothesis?

This is a statement of no difference or no relationships for example there is no difference in the concentration levels of participants in the loud and soft noise conditions

12

What is the abbreviation for the alternative hypothesis

H1

13

What is the abbreviation of a null hypothesis?

H0

14

Why have directions?

Psychologists sometimes use a directional hypothesis instead of a directional one because it makes sense to expect one condition to be better than the other example when thinking of the noise and concentration experiment we might that loud noise would reduce concentration therefore it makes sense to use a directional hypothesis
