Questiontwo

Magnitudeis a property of measurement in which the ordering of numbersreflects the ordering of variables (Sarah, 2012).

Questionfour

Anintervalscale is a scale in which the units of measurement between thenumbers on the scale are all equal in size

Questionsix

Reactivityoccurswhen subject act unnaturally because they know they are beingobserved.

Questioneight

Interraterreliabilityproduces a reliability coefficient that assesses the agreement ofobservations made by two or more raters or judges.

Questionten
