Types of experiments

• What is a Laboratory Experiment?

  Defined by the hight level of control the researcher has over all variables in the study.
• What is controlled in a Lab experiment?

  The experimenter will control environmental factors eg noise and temperature as well as the experience each participant has by using standard producers.
• What is the independent variable in a Laboratory experiment?

  The indecent variable is changed (manipulated ) by the researcher between conditions of the experiment. any change in the Dependent variable will be measured while all other variables that could change the DV are kept the same between conditions.
• what is an advantage of Lab experiments?

  By keeping all of the variables outside of the IV and the DV consistent, researchers can be confident in establishing a cause and effect relationship between changes in the IV. and experiments are easily replicated.
• what is disadvantage of a Lab experiment?

  The have a lack of ecological validity- study cannot be compared to real- world situations, they lack madame realism- lowing externals validity. participants are aware that they re in a study - they might change their behaviour.
• What is a Field experiment?

  Defined by conducting the experiment in naturalistic settings. this change in location is a attempt to avoid artificial nature of lab studies.
• where are field experiments conducted?

  Locations field studies are conducted in can include shops, work and schools or any place where the participant would behave naturally.
• Who changes the the independent variable in a Field experiment?

  Independent variables is still change by the researcher between the conditions of the experiment and the researcher then measures the difference in dependent variables.
