Researcher notes are:

Each of the following bolsters confidence in the obtained results of an experiment, EXCEPT:

If you were interested in empirically testing whether the saying, "More money, more problems" is true, which variable would you expect to see change first in order to establish temporal precedence?

In designing an experimental study, the research question is to the experimental hypothesis as:

_____ is a measure that helps determine whether the manipulation effectively changed (or varied) the independent variable across conditions.

What are acceptable ways to randomly assign participants to the control and experimental conditions?

Confederates can be used to increase:

Which of the following represents a nondirectional hypothesis?

Use the following to answer questions Scenario I Scenario I is based on fabricated data inspired by the following study: Curry, N. A. & Kasser, T. (2005). Can coloring mandalas reduce anxiety? Art Therapy: Journal of American Art Therapy Association, 22(2) 81-85. Effect of Coloring on Anxiety Curry and Kasser were interested in examining whether coloring complex geometric patterns reduces anxiety. To that end, they induced anxiety in 84 undergraduate volunteers from their university. Following anxiety induction the participants were divided into two coloring conditions. To determine which condition each participant would be in the researchers put all of their names in a hat. The first name drawn was placed in group 1, the second name drawn was placed in group 2, the third name drawn was placed in group 1, and so on. Those in the complex geometric coloring condition (group 1) were given a paper with a plaid pattern or the outline of a mandala. Those in the control condition (group 2) were given a blank piece of paper. After 20 minutes of coloring all of the participants completed a self-administered State Anxiety Inventory (SAI). Lower SAI scores indicate low levels of anxiety whereas higher SAI scores indicate high levels of anxiety. The mean SAI scores of each coloring condition were compared to determine whether the type of coloring one does affects anxiety. The results revealed that those who colored a complex geometric pattern had significantly different levels of anxiety than those who colored on a blank sheet of paper. Curry and Kasser concluded that coloring causes a change in anxiety, but only when coloring requires a certain amount of attention and focus. Figure 1. Effect of Coloring on Anxiety -(Scenario I) "Anxiety levels will not differ between those who color complex designs and those color free-form" is an example of a(n):

Each of the following makes a measure more sensitive, EXCEPT:

Lucy is using her newfound scientific appreciation to study phenomena in her own life. This week she wants to conduct an experiment to test whether the dryer is shrinking her jeans. In her study, jeans that are washed and then air dried are her _____ condition.

If Emmanuel is concerned about social desirability bias having an impact on his results, he should choose to use which of the following?

Jasmine is a health psychologist who is interested in experimentally investigating whether massages increase psychological well-being. In her study, participants are either assigned to receive one massage a week for a month or no massages during the month-long study. The independent variable in Jasmine's study is operationally defined as:

Jayla's experimental study revealed a significant result. Which of the following will help to increase her confidence in her findings?

The _____ sensitive a measure is, the _____ ability it has to detect a difference between the experimental and control group.

Which of the following requires examination using experimental research?
