By assigning numerical values to descriptions of observed behaviors, psychologists can transfer __________ data into ___________ data.
A cross-sectional research study analyzes the same group of subjects over a long period of time.
The larger pool of subjects from which a study group is chosen is called the __________.
A psychologist whose goal is to describe a behavior will __________.
In an experiment, the group not receiving treatment is also referred to as the __________ group.
Read the data example below and answer the question that follows. The subject was placed in a strange room and appeared highly anxious, often fidgeting and glancing out the window every few seconds. What type of data is represented?
The control group in an experimental study will __________.
One of the primary benefits of a survey is that they __________.
Which of the following is an example of convenience sampling?
All of the following are reasons that psychologists use a systematic method to conduct research except __________.
What is the difference between the control group and the experimental group in an experimental study?
The experimental group receives the independent variable or treatment being studied. The control group does not receive the experimental treatment, so researchers can compare the two groups and determine the treatment's effect.
Describe the difference between convenience sampling and quota sampling.
Convenience sampling involves selecting people who are readily available and easy to reach. Quota sampling involves selecting participants until predetermined numbers or proportions for particular categories are filled, such as equal numbers of men and women.
Describe what it means when psychologists state that scientific theories must be supported by empirical evidence.
Responses may vary but should include some or all of the following information: In order for a fact or hypothesis to be considered scientific, it must be falsifiable; if it were not falsifiable, it would mean it wasn’t testable or replicable and therefore was not based on objective observation. Anything which cannot be tested is not able to be tested by the scientific method and cannot be used to build more complicated theories. Responses may vary but should include some or all of the following information: Stating that a scientific theory must be supported by empirical evidence means that the theory must be supported by testing it out through research. If research results demonstrate that the psychological claim has been backed by data in a significant manner then accuracy for the theory is established and the theory is said to be backed by empirical evidence.
Which of the following is a disadvantage of conducting a laboratory experiment?
Describe the difference between longitudinal and cross-sectional research.
Explain two reasons why psychologists use a systematic method for collecting and analyzing research data.
Read the scenario below and answer the question that follows. A researcher wants to observe the playground behavior of preschoolers. In order to conduct the experiment, video cameras are secretly placed in several areas of the playground. The researcher is conducting the research by using which descriptive research method?
