Triangulation Triangulation: We learn more by observing from multiple perspectives than by looking from only a single one Improves the accuracy of the research

Triangulation Triangulation of measures: Taking multiple measures of the same phenomena Triangulation of observers: Multiple observers/ researchers bring a fuller picture of a phenomenon Triangulation of theory: Using multiple theories to plan a study or interpret data. Each has certain assumpitons and concepts Triangulation of method: Mixes the qualitative and quantitative research approaches and data. The research becomes richer and more comprehensive.

Triangulation: Examples Research Topic: The amount of violence in popular American films Measures: The frequency (number of killings, punches), intensity (volume and length of time screaming, amound of pain in face and body), level of explicit graphic display (showing a corpse wtih blood flowing, close-ups of injury) in films Observers: Have five different people independently watch, evaluate and record forms and degrees of violence in a set of 10 highly popular American films

Triangulation: Examples Theory: Compare how feminist theory, functional theory and symbolic interaction theory explain the forms, causes and societal results of violence that is in popular films Method: Conduct a content analysis of 10 popular films As an experiment, measure the responses of experimental subjects to violence in each film Survey attitudes toward film violence among the public Make a field observation on audience behavior during and immediately after watching the films

Quantitative vs. Qualitative Research Aspect Quantitative Research Discover ideas; Used in exploratory research with general research topics Common Purpose Hypothesis testing; Specific research questions Observe and interpret Focus Measure and test Unstructures, flexible Data Collection Approach Structured, standard Researcher highly involved Results are subjective Researcher uninvolved Results are objective Few cases, natural settings Samples Many cases, attaining generalizability Exploratory and descriptive research Most often used for: Descriptive and explanatory research

Quantitative vs. Qualitative Research

Qualitative and Quantitative Research Differences between qualitative and quantitative research approaches in terms of: 1) Nature of data 2) Assumptions of social life 3) What are we trying to accomplish in a study 4) Type of “logic” and research path 5) Researcher characteristics 6) Type of question

1) Nature of Data Qualitative Research Quantitative Research Soft data: Words, sentences, photos, symbols Hard data: Numbers Data collection methods: Field research, interview, natural observation, historical comparative research Data collection methods: Experiment, survey, existing statistics (secondary data), content analysis

2) Assumptions of Social Life Qualitative Research Quantitative Research Interpretive perspective: Positivist perspective: Use a language of “cases and contexts” and of cultural meaning Emphasis on conducting detailed examinations of specific cases in the Use a language of variables and hypotheses Emphasis on precisely measuring variables and testing hypotheses

3) What We Want to Accomplish? Qualitative Research We describe details of a mechanism or process for a limites set of cases We often generate new hypotheses (and theories) => induction Quantitative Research We focus on an outcome or effect that is found across many cases We try to verify or falsify a relationship (hypothesis testing) we already have in mind => deduction

4) Type of “Logic” and Path of the Research Qualitative Research Implicit knowledge from practical activities, specific experiences, individual “judgment calls” Nonlinear path: research proceeds a cyclical, iterative, back-and-forth pattern Quantitative Research Organizing, standardizing, codifying knowledge and practices into explicit rules, formal procedures techniques Linear path: research procees in a clear, logical, step-by-step straight line

5) The Researcher Qualitative Research Emphasis on researcher’s: openness and integrity Validation: Self-discipline and trustworthiness. Researcher takes maximum advantage of personal insights, and life pescpectives Intimate, first-hand knowledge of a setting Quantitative Research Emphasis on researcher’s: neutrality and objectivity Validation: Replication, explicit standard procedures, numerical measurement, anayzing the data with statistics (similar to natural sciences) Objective knowledge

6) Questions Asked Qualitative Research Mostly starts with a vague or loosely defined topic. Specific topic emerges slowly during the study; it may change with new data High flexibility: questions become clear only after we become immersed in the data Quantitative Research A topic is narrowed into a focused question in the very beginning before we design the study and collect data Research questions refer to relationships among a small number of variables

Research Question Both approaches work well with some topics: E. g. Poverty. You can study poverty by examining official statistics, conducting a survey, doing ethnographic field research or completing a historical comparative analysis But some topics are best suited for qualitative and others best suited for quantitative research

Research Question Typical qualitative questions: How did a certain condition or social situation originate? How do people, events, and conditions sustain over time? By what processes does the situation change, develop or end? Typical quantitative questions: Associations, relations “Is age at marriage associated with

Ways to Select a Research Topic: Personal experience, everyday life and personal values State of knowledge in the field Social premiums; curiosity based on media Solving a problem

How to Narrow the Topic into a Research Question: Examine the literature Talk over ideas with others Ask people who are knowledgeable about the topic; seek out others’ opinions Apply a specific context Published articles are excellent sources of ideas for research questions. They provide lots of suggestions Focus on a specific time period, society, catgeory, subgroup or geographic unit Define the aim or desired outcome of the study

Good and Bad Research Questions

Quantitative Design: Variables Variable: Empirical measure of a concept that can take multiple values Attributes: Categories or levels of a variable For Example: gender is a variable; male is an attribute marital status is a variable; married is an attribute

Quantitative Design: Variables Independent Variable: Variable that produces an effect or result on the dependent variable in a causal hypothesis Dependent Variable: The effect or result variable that is caused by the independent variable Intervening (Mediating) Variable: Comes logically or temporally after independent variable and before dependent variable; helps to show the link or mechanism between them

Quantitative Design: Hypotheses Causal Hypothesis: Statement of a causal explanation or proposition that at least one dependent and one independent variable and yet to be empirically tested Characteristics of causal hypotheses: At least 2 variables (dependent and independent) Expresses a cause-effect relationship Can be expressed as a prediction Logical link between hypothesis and theory Falsifiable

Quantitative Design: Hypotheses Logic of Disconforming (“Falsification”): Testing for no relationship provides more cautious support for possible existence of a relationship. Negative, disconforming evidence is more significant. *We never prove a hypothesis; but we can disprove it! Null Hypothesis: states that there is no significant effect of the independent variable on the dependent. Alternative Hypothesis: paired with the null

Potential Errors in Causal Explanation

Potential Errors in Causal Explanation

Potential Errors in Causal Explanation

Potential Errors in Causal Explanation Reductionism: An error in explanation in which empirical data about associations among small-scale units of analysis are greatly overgenralized Example: Did World War I really occur because a Serbian shot an archduke in the Austria-Hungarian Empire in 1914?

Potential Errors in Causal Explanation Spuriousness: An apparent causal relationship is illusionary due to the effect of an unseen, hidden causal factor Example:
