The counting rule that is used for counting the number of experimental outcomes when n objects are selected from a set of N objects where order of selection is not important is calledQuestion 8Select one:a.permutationb.None of these alternatives is correctc.combinationd.multiple step experiment

Assuming the experiment was balanced: the number of different treatments used in the experiment, and the number of subjects (separate observations) for each treatment wereGroup of answer choices5 subjects on each of 4 treatments5 subjects on each of five treatments6 subjects on each of 4 treatments6 subjects on each of 5 treatments30 subjects on each of 4 treatments

Suppose we want to choose 4 objects, without replacement, from 18 distinct objects.(If necessary, consult a list of formulas.)(a) How many ways can this be done, if the order of the choices does not matter?(b) How many ways can this be done, if the order of the choices matters?

Which of the following best describes combination?Group of answer choicesorder of the objects does mattercounting principles are appliedsame results occurs when positions of objects are switcheddifferent results occurs when positions of objects are switched

In which of the following procedures are participants assigned to different experimental groups on the basis of chance and chance alone?Multiple Choiceoperationalizationrandom sampling methodcorrelationrandom assignment to condition

Two numbers are selected from the set {2, 4, 6, 8}. What is the difference in the number of possible outcomes if the experiment is undertaken with replacement or without replacement?
