Three persons deserve special recognition. D.N. Lawley of the University of Edinburgh published a paper in 1943 showing that many of the constructs of classical test theory could be expressed in terms of parameters of the item characteristic curve. This paper marks the beginning of item response theory as a measurement theory. The work of Dr. F.M. Lord of the Educational Testing Service has been the driving force behind both the development of the theory and its application for the past 50

Graphical analysis assignment. NAME: COURSE: INSTITUTION: INSTRUCTOR: DATE: The given graph shows a shift of the demand curve to the right. This is an increase in demand. This change results due to influencing factors other than prices such as an increase of number of consumers and a positive change in terms of consumer taste and preference. A good example is DVD’s. In this case‚ let our original price of DVD’s be 40 and our original quantity demanded of DVD’s be 20. At a price of 50 a shift to

some of his indifference curves. The consumer will choose the “best” indifference curve that he can reach given his budget. But when you try to do this‚ you have to ask yourself‚ “How do I find the most desirable indifference curve that the consumer can reach?” The answer to this question is “look in the likely places.” Where are the likely places? As your textbook tells you‚ there are three kinds of likely places. These are: (i) a tangency between an indifference curve and the budget line; (ii)
