Document Summary

It is based on measurement that are objective, valid, and reliable. Inter-rate reliability, meaning that the raters agree on the measurements that were taken: reliability and validity are essential components of scientific research. Demand characteristics, inadvertent cues given off by the experimenter or the experimental context that provide information about how participants are expected to behave. Placebo effect, a measureable and experienced improvement in health or behaviour that cannot be attributable to a medication or treatment. Single-blind study, the participants do not know the true purpose the study, or else do not know which type of treatment they are receiving. Double-blind study, a study in which neither the participant or the experimenter knows the exact treatment for any individual. Replication is the process of repeating a study and finding a similar out-come each time. Five characteristics of poor research: falsifiable meaning that the hypothesis is precise enough that it could be proven false.
