Document Summary

Validity and reliability if something is not reliable, it can"t be valid assessing reliability: parallel- is it true that the outcomes would both be similar validity: how true is a measure; can be very narrow construct. Exam 1 scantron bring cheat sheet; make photocopy because it must be turned in aterwards cheat sheet can be double sided; it can be typed or hand writen (8. 5x11) Research quesion: i wonder if posiivity of the most compelling alternaive related to emoional response. Null hypothesis: the posiivity of mca (most compelling alternaive) will not be related to emoional response. Research hypothesis: the posiivity of the most compelling alternaive will be inversely/negaively related to emoional response. Operaional deiniion: medal placing, speciically geing a silver versus bronze medal (posiive most compelling alternaive-silver; negaive most compelling alternaive- bronze) This is measured and an observaion (not manipulated)
