Measure – operational version of your concept or variable Measurement – limiting the data of any phenomenon so that those data may be interpreted and compared to an acceptable standard of quality or quantity. Anything that exists can be measured by a researcher. Measurement is ultimately about comparison. The instrument that you use, or more likely you design, to measure these insubstantial ‘things’ will be effective only if it is valid & reliable. Validity: the extent to which the instrument measures what it is supposed to measure Reliability: the consistency with which a measuring instrument yields certain results when the characteristic being measured hasn’t changed.

Method of Research: Observations because researchers are ‘testing; their hypothesis (quantitative) or formulating a theory (qualitative)to answer the research question. We call our research observations 'empirical tests' (p, 18) Indirect methods – methods of data collection that don’t involve contacts between the researcher and subjects - unobtrusive Indirect sources or secondary sources – libraries; minutes from corporate board meetings; headstones in a cemetery, Direct methods – method of data collection in which data are obtained personally from subjects or respondents. Direct sources or primary sources -Interviews, questionnaires observation of behavior

Qualitative Research Quantitative Research Purpose or Use: correlations, relationships, effects, differences, predictability Variables: independent and dependent (cause & effect) Hypothesis: yes Sample size: often large Participants: random/convenient – intended to allow results to be generalized Methods: surveys, observations, other Measurements: statistical Reporting results: Statistics, generalizability of results, validity, reliability Implications for future research: change sample population, narrow research question, study alternative constructs, change data collection method, replicate study to test results Purpose or Use: discovery, gain new perspectives, accepts dynamics of the social world, Identify variables that can later be measured quantitatively Variables: none Hypothesis: rarely Sample size: often small Participants: targeted --- not necessarily meant to generalize results Methods: observation, surveys, informal interviews Measurements: discovery, coding themes Reporting results: depends on purpose -generate theory, conceptualization, instrument development (see table 1 handout) Implications for future research: narrow focus, expand to other groups, expand to other phenomena, change data collection method

Qualitative research contributes to the scientific inquiry process Psychologists, Sociologist, & Business including Human Resources & Marketing Understanding customer reaction to products and services Evaluating organizational change Methods include surveys, focus groups & interviews with stakeholders such as customer, employees and management Observation and analysis of human opinions and behavior (ex: secret shoppers) Analyze artifacts such as marketing literature, training documents, graduation programs, schedules

Concepts or constructs - variables that are not directly measurable such as: financial situation, classroom atmosphere, occupational status, study habits, desire for college degree, clear career/educational goals, using Career Services resources, attitude toward attendance

Research Methods unit 2 lecture Thinking through your options
Who are you going to study? Research question: Why is the ratio of men to women at ITT Rancho Cordova approximately 75% to 25%? How are you going to do your research? You might decide to do a survey of all male and female students using a PRE-CODED questionnaire with reasons why they decided to enroll and the factors affecting their decisions to stay. OR you might decide to do a case study of three women students as compared to three men students -- doing in-depth interviews about their reasons for enrolling and staying on the campus. Both of these approaches would answer the question in a different way. . That is, the out come of a survey might be very different from that of a case study.

Research Methods unit 2 lecture Thinking through your options
When deciding on the approach you want to take, you need to take into consideration these factors: What resources do you have at your disposal? Which approach do you feel most comfortable with? What is the overall purpose of your research and how do you intend the findings to be used? Does the method you choose affect bias within your research? Have you ‘controlled’ the variables: made sure there isn’t some other factor (confounding variable) effecting the outcome, this takes contemplation and deliberate planning Are there ethical implications, such as protecting the identify of participants?

Research Methods unit 2 lecture Thinking through your options
You must decide how you will conduct the research by describing the method that will be used to measure your concepts or constructs and by deciding which method(s) you use to collect the data Then the researcher conducts the research by 1) reviewing data from indirect i.e. (literature review) and 2) by doing his / her observations and / or surveying i.e. Note: Longitudinal study: takes place over an extended period of time. A quantitative research paper will describe the results, discuss the results, interpreting the data and confirm or refute the hypothesis The qualitative research paper will draw conclusions by conceptualizing and theory building. The research paper may make recommendations for future research.

Accuracy: Is the author's point of view unclear? Is the author's point of view flawed? Does the author have a bias — political, ideological, or cultural? Does the author hope to persuade you in some way? If the answer to any of these questions is yes, then the source will not be useful. In regard to items # 3 & 4 both of these imply the author(s) had a preconceive answer to the question. His or her bias will interfere with your research.
