A question about operational definitions of a variable is included.

Which of the following operational definitions of a variable would suffer from effective range problem _____________ (a) a standard IQ test administered to high school seniors in a study of the relationship of intellibence to dating patterns (b) a very difficult mathamatics reasoning test given to a group of college mathematics majors in a study to determine the effects of high anxiety on test performance (c) a standard bathroom scale to measure the weight of chickens in a study to determine how chicken size affects pecking order (d) a wristwatch with a second hand to measure the time it takes students to solve 10 anagram problems in a study of effects of noise on problem-s... click for more

research methods

One of the advantages of frequency polygon is that _____ (a) with a small number of participants, it looks like a smooth curve - not true (b) it primarily produces bell-shaped curves - true (c) two frequency distributions can be compared easily (d) it produces a more attractive representation of data Please advise answer & why - thanks!!

A question about naturalistic methodology is offered.

A researcher uses naturalistic methodology to study dating behavior in college students. He/she finds the behavior on dates is strongly affected by alcohol (i.e., the more students drink alcohol the more uninhibited they become during dates). With this information ______________ (a) establish a specific proposition that alcohol affects dating behavior (b) establish a general proposition that alcohol affects dating behavior (c) state that the behavior of college students on dates is related to how much alcohol they drink (d) negate a general proposition that alcohol affects dating behavior This question is included.

A question about experimentation is noted.

The following two questions appear to be the same problem asked different ways: 1. One of the major characteristics that differentiates experimentation from other levels of constraint is ____________ (a) the high degree of control exerted over both the procedures in general and the independent variable in particular (b) that we don't care about establishing causality in experimental research (c) that control groups are unimportant in experimentation (d) the number of participants 2. One of the major differences between experimental research and research from from other levels of constraint is ____________ (a) that causality is not possible to establish ... click for more

Research Methods

Experiments are conducted not only to find evidence for a position, but also to ____ avoid tentative conclusions, prove one's theory, rule out rival hypotheses, determine the absolute truth I feel the - prove one's theory or rule out rival hypotheses could be the answer - but feel - prove one's theory is the best answer. Please advise answer & why. Thanks!!!
