Before any scientific article, journal, or experiment can be posted, the findings must first meet standards of both reliability and validity. stimulus The most likely source of invalid results stems from our inability to draw appropriate conclusions from the information we have found. It is noted that reliability problems crop up in many forms.

Within the domain of psychological research methods, any errors in the reliability and validity of a test or experiment are very detrimental to the value of the research. Purpose (empirical), what are the subcomponents of motor behavior? It can be enhanced by detailed field notes by using recording devices and by transcribing the digital files. motor learning - skills acquired - how do you enhance performance of that skill; re- Interobserver Reliability. Movement Total variability, Absolute error (AE) -> indication of overall accuracy in the performance without regard to acquiring skills If you use scores or ratings to measure variations in something (such as psychological traits, levels of ability, or physical properties), its important that your results reflect the real variations as accurately as possible.
