What is a quasi-independent variable?

• a factor other than the intended treatment that might change the outcome variable

• a variable that is treated as if they are independent variables in the experimental design even though the researchers do not manipulate them

• a variable that can be classified into two or more distinct groupings

• a variable with an infinite number of different values between two given points

Which of the following is NOT an example of a quasi-independent variable

• gender

• eye color

• trauma experienced throughout lifetime

• environment of research setting

What is a demand characteristic?

• a cue that potentially makes participants aware of what the experimenter expects

• variation from the measure's true score due to unsystematic or chance factors

• freely choosing any participant as long as they help meet predetermined targets for the sample's characteristics

• a comparison group often used in clinical research in which an already established treatment is administered for comparison to experimental treatment.

A ---------- observation is a measure that relies on directly seeing or observing behavior as it occurs.

What is bias?

• Error that consistently pushes scores in a given direction; systematic

• What your score would be if it was free of extraneous factors

• variation from the measures true score due to unsystematic or chance factors

You ask 100 history majors how interesting they find World War I and notice that almost everyone chooses either a 6 or 7 on your 7-point measurement scale. Which of the following may be a problem with your measurement?

• Scorer bias

• Ceiling effect

• Systematic error

• Floor effect

If the speedometer in your car consistently shows that you are going more slowly than you actually are, it has which type of error?

• Random error

• Nonstandardization error

• Bias

• Nonsystematic error

Which of the following is NOT a sampling method?

• Cluster random sampling

• Visual sampling

• Convenience sampling

• Snowball Sampling

You are convinced that an exam was unfair because none of the questions even remotely resembled what was taught in the class. In this case, you are questioning the exam's:

• reliability

• reactivity

• validity

• sensitivity

What is the "College Sophomore Problem" as described in our textbook?

• Researchers use data collection from college sophomores without their clear consent and understanding of what being in research means.

• Researchers not using data collection from college sophomores because they are stereotyped as overbearing.

• Researchers avoiding using data collection from college sophomores, leading to them being an under-researched demographic.

• Researchers using data collection from college sophomores using convenience sampling and implicit assumption that the results are universal to all humans.
