Document Summary

Anxiety- physiological (can collect data without verbally asking ex:palms), emotional responses. Experience in the world is subjective, using this is more reliable. Reliability- psychological measure- consistent measure (can take it many times, get same score each time) Can be reliable but not be valid. (ex: are you alive? assume everyone says yes. Doesn"t actually tell you whether someone is dead because a dead person can"t say yes) not valid but reliable. (ex: taller -> weigh more *positively correlated, both goes up* Negatively correlated-> x goes up, y goes down. Applied research- take phenomenas and attempt to develop policies, recommendations, etc to improve. Theories- inductive logic (bottom up- use all data points to work up to conclusion) collect data->analyze->what theories explains data. Hypotheses- deductive logic (top down, start from top, go to bottom) start with assumption-> what else has to be true. we can provide absolute truth to conclusion.
