Methods Of Behavioral Research Already Passed

reactivity {Ans: A problem of measurement in which the measure changes the behavior being observed.}field experiment {Ans: An experiment that is conducted in a natural setting rather than in a laboratory setting.}ratio scale {Ans: A scale of measurement in which there is an absolute zero point, indicating an absence of the variable being measured. An implication is that ratios of numbers on the scale can be formed (generally, these are physical measures such as weight or timed measures such as duration or reaction time).}Cronbach's alpha {Ans: An indicator of internal consistency reliability assessed by examining the average correlation of each item (question) in a measure with every other question.}face validity {Ans: The degree to which a measurement device appears to accurately measure a variable.}Exempt research {Ans: ...}
