Lab experiments

• 1. Conducted in a tightly controlled environment
• 2. The experimenter measures the dependent variable
• 3.the experimenter manipulates the IV
• 4. The experimenter controls the EV
• 5.The procedure is standardised

Lab experiments

• One strength of lab experiments is that it is controlled.Due to the fact that it is a lab experiment it has control over the temperature . the researcher can therefore show it is purely the IV affecting the DV. This adds validity to lab experiments as it means that cause and effect relationship can be established.
• Another strength of Lab experiments is that they can be easily replicated.As the lab experiments are controlled ,and instructions are standardised. This makes it easy to replicate as everything is specifically recorded.Therefore this adds validity to lab experiments.
