What is the purpose of a hypothesis in research?
To prove the researcher's theory
To predict the relationship between variables
To collect data from participants
To analyze the results of the study
What does a one-tailed hypothesis test look for?
No change in the dependent variable
An increase or decrease in the independent variable
A specific direction of change in the dependent variable
Any change in the dependent variable
In an experiment, what is the independent variable (IV)?
The variable that is manipulated
The variable that is observed
The variable that remains constant
The variable that is measured
What is a key characteristic of a true experiment?
It is conducted in a natural setting
Participants are not randomly allocated
It lacks external validity
All variables are controlled
What is a limitation of field experiments?
Difficulty in replication
Control over extraneous variables
High internal validity
Low external validity
What is the main focus of correlational research design?
To manipulate the independent variable
To control extraneous variables
To measure the relationship between two variables
To establish cause and effect relationships
What is a repeated measures design?
Different participants complete each condition
Participants are randomly assigned to conditions
Participants are matched based on traits
The same participants complete all conditions
What is a strength of matched pairs design?
It is easy to replicate
It controls for order effects
It requires fewer participants
It eliminates participant variability
What is a common issue with independent measures designs?
Demand characteristics
Participant variability
Order effects
Fatigue effects
What is the purpose of using a double-blind control in research?
To eliminate researcher bias
To increase external validity
To reduce participant variability
To ensure random allocation
Which of the following best describes the difference between positive correlation and negative correlation?
Positive correlation indicates that as one variable increases, the other variable decreases, while negative correlation indicates that as one variable increases, the other variable also increases
Positive correlation indicates that as one variable increases, the other variable also increases, while negative correlation indicates that as one variable increases, the other variable decreases.
Positive correlation means there is no relationship between the two variables, while negative correlation indicates a strong relationship
Both positive and negative correlations indicate that variables are unrelated
