Data in psychology

• What is primary data in psychology?

  Data collected for a specific reason and reported by the original researcher.
• Why is primary data considered authentic?


  Because it is collected to suit the aims of the research.
• What is a disadvantage of gathering primary data?

  It can take a long time and effort to gather.
• What is secondary data in psychology?

  Data collected by other researchers for a purpose other than the current investigation.
• What is an example of secondary data?

  Data from government reports.
• What is a benefit of using secondary data?

  It is less time-consuming to gather since it already exists.
• What is a disadvantage of secondary data?

  It may not be fit for the purpose since it is being used for unintended purposes.
• What is qualitative data?


  Non-numerical data expressed in words, such as an interview transcript.
• Why is qualitative data harder to analyze than quantitative data?

  Because it is more time-consuming and subjective.
• What is a benefit of qualitative data?

  It provides more insight into human behavior than quantitative data.
• What is quantitative data?

  Numerical data that can be statistically analyzed.
• Why is quantitative data easier to analyze than qualitative data?

  Because statistical significance can be worked out.
• What is a disadvantage of quantitative data?

  It may lack the insight that qualitative data offers.
• What is interval data?


  Data where intervals between each value are equal in measurement.
• What is an example of interval data?


  Scientific measurements, such as length or weight.
• What is ordinal data?


  Data that is ordered in some way, but the intervals between the data are not equal.
• Give an example of ordinal data.

  Attitudes towards politics on a scale of 1-10.
• What is nominal data?

  Categorical data, such as the number of males and females who are left or right-handed.
• What is a characteristic of discrete data?


  Participants will only appear in one category.
• What type of data is used for scientific measurements?

  Interval data.
• How is ordinal data different from interval data?

  Ordinal data has ordered values with unequal intervals, while interval data has equal intervals.
• What are the key differences between primary and secondary data?

  • Primary Data:
  • Collected for a specific reason by the original researcher.
  • Authentic and fit for the purpose of the investigation.
  • Time-consuming to gather.

  
  

  • Secondary Data:
  • Collected by other researchers for different purposes.
  • Less time-consuming to gather.
  • May not be relevant to the new study's aims.

  
• What are the differences between qualitative and quantitative data?

  • Qualitative Data:
  • Non-numerical, expressed in words.
  • Harder to analyze, more insightful about behavior.
  • Analysis can be subjective.

  
  

  • Quantitative Data:
  • Numerical, can be statistically analyzed.
  • Easier to analyze, may lack insight.
  • Analysis is more objective.

  
• What are the different levels of data in psychology?

  • Interval Data:
  • Equal intervals, e.g., scientific measurements.

  
  

  • Ordinal Data:
  • Ordered but unequal intervals, e.g., attitudes on a scale.

  
  

  • Nominal Data:
  • Categorical, e.g., number of males and females.
