 Define Reliability Refers to consistency or stability of the measure Must work exact same way each time it is used to be reliable Define Method Error Error from the experimenter and testing situation or design What are errors in measurment? Method and Trait Errors Define Trait Error Error from the subject examples...Giving wrong information (faking good or bad), forgetting events What is an observed score? Observed score = true score + measurement error What is the formula for Reliability? True Score __________ True score + error score No error...Reliability = 1 or -1 What is a correlation coefficient? Value that indicates the strength of the relationships between two variables ex) hours watching tv correlates with hours playing video games r score range from -1.00 to + 1.00 further from 0 = stronger correlation closer to 0 = weaker correlation Define test/retest reliability What are problems associated with test/retest Test people twice to see if their scores are stable reliable test scores should be the same each time they are measure Practice effects - people get better at answering the questions the second time around, so the correlation gets weakended short interval - if the time between completing the measure is short, people might remember how they responded to the questions (tests their memory, not reliability of the measure Define alternate forms reliability two different alternative froms tests Tests are equivalent Split-Half reliability Split items on a measure in half and correlate the two halves total 50 items randomly split the scale in half (25 & 25)
