What are advantages to lab experiments?
-Variables are controlled (standardised).
-Replicable.
What are advantages to field experiments?
-Naturalistic (high ecological validity).
-Controlled IV.
What are advantages to quasi experiments?
-Controlled conditions, replicable.
-Establishes cause-and-effect.
What are advantages to natural experiments?
-High ecological validity.
What are disadvantages to lab experiments?
-Experimenter bias.
-Low ecological validity.
What are disadvantages to field experiments?
-Ethical issues (lack of consent).
-No control over extraneous variables.
What are disadvantages to quasi experiments?
-Can’t randomly allocate participants.
What are disadvantages to natural experiments?
