Unit 2 Notes:

Research Methods:

  • Hindsight Bias: The tendency to believe, after learning the outcome, that you knew all along.


  • The Barnum Effect: It is the tendency for people to accept very general or vague characterizations of themselves and take them to be accurate. 
  • Applied Research has clear, practical applications.
  • Basic Research explores questions that you may be curious about, but not intended to be used immediately.


This video will tell you the difference between applied and basic research:


  • Descriptive Research is any research that observes and records. Also, it does not talk about relationships, it describes it. 

    • Types of Descriptive Research:
       
    1. The Case Study: often includes face to face interviews. its one type of observational data collection technique in which on individual is studied in depth in order to identify behavioral, emotional, and cognitive qualities.
    2. The Survey: method for collecting info and data as reported by individuals. 
    3. Naturalistic Observation: watches subjects and observe them in their natural habitat.

    • Experimental Research: explores cause and effect relationships
    • Experimental Method:
    1. Blind Study: subjects are unaware if assigned to experimental or control group.
    2. Double Blind Study: neither subjects nor experiments know which group is control or experiment. 
    • Descriptive Statistics vs. Inferential Statistics:
    1. Descriptive Statistics:  describe the results of research
    2. Inferential Statistics: are used to make an inference or draw a conclusion beyond the raw data.

      Out of the three descriptive research methods which do you believe is the best? I think that the survey is the best because it helps to get a very wide range of opinions really quickly/easily.

      Although the survey method is the most common type of study and is beneficial to experimenters because it is cheap and fast, there are negative effects of using the survey method because there is often some sort of confusion that goes on between the actual survey being read and how the information is actually processed the information in the recipient's brain. For example, the wording effects of the survey and low response rate may cause people to lie about the information that they are giving or misinterpret what the experimenter is trying to ask. The first website that you have posted on this blog post is very informative on the three basic types of descriptive research and how they are used to "describe" various situations.
