Descriptive research where one person or group is studied in depth; baby albert

• naturalistic observation
• experiment
• correlational study
• case study

Which of the following is a potential problem for a case study?

• They provide too much detail and the researcher is likely to lose track of the most important facts.
• They are generally  too expensive to economical
• They may be misleading because they don't fairly represent other cases
• The dependent variable is difficult to operationally define in a case study

A testable prediction is called (a/an):

• operational definition
• theory
• replication
• hypothesis

Mary watches several different species of birds to discover how they feed their young in their habitat, without being intrusive. This would be an example of what type of study?

• Case study
• Naturalistic observation
• Survey
• Experiment

All those in a group being studied is referred to as the...

• Random sample
• Representative sample
• Population
• Sampling bias

This is a method of research where the researcher carefully and systematically observes and records behavior without interfering

• Observational
• Correlational
• Experiments
• Case Study
• Survey

This research method is a measure of the extent to which two variables change together, and thus of how well either variable predicts the other

• Correlational
• Experiments
• Case Study
• Survey
• Observational

This is a method of research where an investigator manipulates one or more factors (independent variables) to observe the effect on some behavior or mental process (the dependent variable).

• Experiments
• Case Study
• Survey
• Observational
• Correlational

The disadvantage of this method of descriptive research is that the data is limited to only answering the question(s) asked. These limitations lead to biases, ambiguous conclusions, and low participation rates among research populations.

• Survey
• Observational
• Correlational
• Experiments
• Case Study

Which of the following methods best limits the influence of unknown variables in an experiment?

• Random assignment

• Debriefing

• Stratified Sampling

• Subject matching

• Correlational study
