Study Notes
Conceptualization
- Conceptualization is the process of defining and clarifying concepts.
- In deductive studies, conceptualization occurs early, often before data collection, as part of hypothesis formulation.
- In inductive studies, it occurs after data collection, during the data analysis phase, as patterns and themes emerge.
Sociological Concepts
- Sociological concepts must vary in the sense that they should be able to take on different values or categories, enabling researchers to measure and compare them across different contexts, populations, or time periods.
Measurement and Operationalization
- A measure or indicator is a specific method or tool used to quantify a concept.
- Operationalization is the process of defining how a concept will be measured, specifying the procedures and instruments used to collect data on that concept.
Levels of Measurement
- The four levels of measurement are:
- Nominal: Categories without a specific order (e.g., gender, race).
- Ordinal: Categories with a specific order but no fixed intervals (e.g., education level).
- Interval: Ordered categories with fixed intervals but no true zero point (e.g., temperature in Celsius).
- Ratio: Ordered categories with fixed intervals and a true zero point (e.g., income, age).
Survey Research
- Cross-sectional surveys collect data at a single point in time from different individuals.
- Cross-sectional trend surveys collect data at multiple points in time from different individuals, allowing trend analysis.
- Panel surveys collect data from the same individuals at multiple points in time, enabling analysis of changes within individuals over time.
Survey Items
- Closed-ended items are ideal when the researcher needs quantifiable data, consistency in responses, and ease of analysis.
- Closed-ended items are best used when the range of possible answers is known and limited.
- Open-ended items are ideal when exploring new topics, capturing detailed and nuanced responses, and allowing respondents to express their thoughts freely.
- Open-ended items are useful for qualitative analysis and gaining insights into complex issues.
Missing Data
- Missing data can be caused by respondent refusal, forgetfulness, or misunderstanding questions.
- Missing data is a problem because it can lead to biased results if the missing data are not random.
- Missing data reduces the statistical power of the study and complicates data analysis and interpretation.
Sampling
- A sample is a subset of the target population selected for the study, while a census includes every member of the target population.
- The distinction between a sample and a census is important because samples aim to represent the target population accurately.
- Unit of analysis is the primary entity being analyzed in a study (e.g., individuals, groups, institutions).
- It is important to correctly specify a unit of analysis to ensure accurate results.
Sampling Bias
- Sampling bias occurs when certain members of the target population are systematically excluded or overrepresented in the sample, leading to unrepresentative results.
- Sampling bias can be avoided by using random sampling techniques, ensuring every member of the target population has an equal chance of being selected.
Variables
- Independent Variable: The variable that is manipulated or categorized to observe its effect on the dependent variable.
- Dependent Variable: The variable that is measured to see how it is affected by the independent variable.
- Mediating Variable: A variable that explains the mechanism through which the independent variable affects the dependent variable.
- Moderating Variable: A variable that affects the strength or direction of the relationship between the independent and dependent variables.
Strengths and Weaknesses of Survey Research
- Strengths: Surveys can collect data from a large number of respondents quickly and cost-effectively, are flexible, and can cover a wide range of topics.
- Weaknesses: Surveys may suffer from low response rates, leading to nonresponse bias, and rely on self-reported data, which can be subject to recall bias and social desirability bias.
