Question

One of the best-known techniques for selecting a random sample is the ________________ method. All observations must be represented on slips of paper that are deposited in a bowl and _________________. The through stirring is a very important aspect of this method of sample selection. Another method for generating a random sample involves the use of the table of random numbers. When using this table, the number of digits actually used is determined by the ____________ __________________. This method is not very efficient for obtaining a sample from a ____________ population. In an experiment, although subjects may not be selected randomly, they should be randomly assigned to either the experimental or control condition. The purpose of random assignment is to make sure that, except for __________________ differences, groups of subjects are similar with respect to any ____________________________________________. It is usually desirable that _____________ numbers of subjects be assigned to the experimental and control groups. To accomplish this, assignment should be done in ______________________.

Another method for generating a random sample involves the use of the table of ___random___ numbers. When using this table, the number of digits actually used is determined by the _population_ size____. This method is not very efficient for obtaining a sample from a ______hypothetical______ population.

In an experiment, although subjects may not be selected randomly, they should be randomly assigned to either the experimental or control condition. The purpose of random assignment is to make sure that, except for __random___ differences, groups of subjects are similar with respect to any ___uncontrolled variables________. It is usually desirable that ____Equal_________ numbers of subjects be assigned to the experimental and control groups
