For the scenarios below indicated which type of reliability is most important for the assessment situation described. a)   An exam is developed for use as an end-of-course examination.  Interest is in the consistency of the items to measure the construct.   b)  Different judges are evaluating the degree to which art portfolios meet a set of standards.   c)  A researcher is using an experimental design with a pretest and posttest.   

What is the difference between a true experimental design, a quasi-experimental design, and a pre-experimental design?

The letter of Second Corinthians was probably a combination of ______ letters written by Paul to them.

Read the scenario below to determine which one of the three factors that influence reliability (instrument, group, test administration) is of most concern to the scenario.  A proctor for an end-of-course examination decides to allow students to eat during the exam since the exam is near the lunch hour.  The proctor instructs the students to be as quiet as possible during the exam and to remember they only have two hours to finish the exam.  Several students complain there is too much noise.  Some students do not finish the exam.  

Define  random assignment. What role does random assignment play in internal validity?

A sample of blood is placed in a centrifuge of radius 11.0 cm. The mass of a red blood cell is 3.0 ✕ 10−16 kg, and the magnitude of the force acting on it as it settles out of the plasma is 4.0 ✕ 10−11 N. At how many revolutions per second should the centrifuge be operated?

A 4.00-kg mass sitting flat on a table is pushed to the right by a force of 12.0 N.  However, the force of static friction keeps it in place.  If the coefficient of static friction is 0.500, what is the force of static friction pointing left?

James writes, “Religion that God our Father accepts as ________ and faultless is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world.”  

Paul’s name apears in the greeting of __________ New Testament “letters,” nearly half the “books” in the New Testament.
