LECTURE # 9 DATA ANALYSIS
QUESTIONS
What are the THREE types of Quantitative Data Analysis?
o Univariate
o Bivariate
o Multivariate
What is the main goal of Qualitative Data Analysis?
o To find themes and patterns in the data
What are the TWO main core procedures for Qualitative Data Analysis?
o CODING Classification of Phenomena
o MEMOING
What is OPEN CODING?
o Making sense of massive amounts of qualitative data by trying to identify as
many themes, ideas and patterns as possible
o Identification is the main purpose
What is the CONSTANT COMPARATIVE METHOD?
o Constantly comparing each new piece of data against the codes and notes
Why is NAMING important?
o It is important to pay attention to the exact words used as each word
depending on the form and word used evokes so much meaning. Therefore
be as precise as possible with the words used.
What is AXIAL/FOCUSED Coding?
o What this type of coding you are always looking at how themes are useful
and how they are related, and interact with one another.
o It is used to develop new categories and seeking new relationships that will
further shed light on an existing category
o Main purpose is links and relationships
What is a CORE CATEGORY?
o It is the central code or principle around which other codes cluster around
o It is easy to relate to, appears frequently, supports theories and moves ideas
forward
o Gives central meaning to the research conclusions
o Main them of the situation and may represent a central problem or issue.
What is SELECTIVE CODING?
o Increases the focus around the central category by always looking at links to
it and how it may or may not be at the heart of the matter
o It is essential for integration.
What is TRIANGULATION?
o It is using a third source outside of the cause to corroborate the results and
apparent relationships from your coding to know you are on the right path
and what you are interpreting is consistent with other accounts if possible.
What are the FIVE elements of CODING according to Boyatzis (1988)
o Label
o Definition
o How to know when the theme occurs?
HLTB15 WINTER 2013
o Qualifications or exclusions?
o Examples to eliminate possible confusion
What is MEMOING?
o Writing down ideas and insights about the data and can happen at any time
o Identify concepts, half formed ideas, action notes hoping to reach more
cohesiveness?
What are the THREE TYPES OF MEMOING notes?
o Code Notes
o Theoretical Notes
o Operational Notes
What is CODE notes?
o Indicates the code label
o Provide information on the meaning and definition
o Meanings in everyday language
What are THEORETICAL notes?
o Memos that elaborate conceptual meanings, connections and relationships
o Lay out theoretical propositions
What are OPERATIONAL notes?
o Issues of method and procedure
What are INITIAL memos? EMERSON
o Details the series of discrete phenomena, topics, and categories
What are INTEGRATIVE memos? EMERSON
o Seek to clarify and link analytic themes and categories
What are ELEMENTAL memos?
o Detailed analytic rendering of some specific matter
What are SORTING memos
o Used for organization and summary
What are INTEGRATING memos?
o Articulates relationships and connections
What FOUR software help to manage QUALITATIVE DATA?
o Word processing program, Nvivo, ATLAS.ti, Hyper-RESEARCH
o Facilitate the management of unordered data
o Generation and interpretation still done by researcher
What is a CODEBOOK?
o Document that tells you the location of different data in a file and the
meaning of the codes
What is Data Cleaning?
o Process of detecting and correcting coding errors
What are the TWO types of DATA CLEANING?
o Possible code cleaning
What is POSSIBLE-CODE CLEANING?
o When a code that doesn’t fit is put
What is CONTINGENCY CLEANING?
o When there are consistentency and validity issues present
What are the FOUR types of variables?
o Nominal, Ordinal, Interval, Ratio, NOIR
What is a NOMINAL VARIABLE?
o Values based on categories
What is ORDINAL VARIABLE?
HLTB15 WINTER 2013
o Ranking of categories or pout them in order
What is INTERVAL VARIABLE?
o Measurement scale that uses the same scale throughout O is arbitrary
What is RATIO VARIABLE?
o There is a true zero point as with height
What is UNIVARIATE ANALYSIS?
o Distribution of cases of only one variable
What are the THREE measures of CENTRAL TENDENCY?
o Mean, Median, Mode
What are the TWO measures of DISPERSION?
o Range, Standard Deviation
What is BIVARIATE ANALYSIS?
o Analysis of 2 variables simultaneously, determining the relationship
between them
What is an INDEPENDENT VARIALBLE?
o Outcome of interest
What is a DEPENDANT VARIABLE?
o Variable of Interest
What is CONTROL VARIABLE?
What is MULTIVARIATE ANALYSIS?
o Analysis of the simultaneous relationships among several variables
What are the different types of MULTIVARIATE ANALYSIS?
o Multiple regression analysis, Logistic regression analysis, Anovas, Partial
least squares
What type of SOFTWARE assists with QUANTITATIVE ANALYSIS?
o SPSS, SAS, Statistical Software

## Document Summary

What are the three types of quantitative data analysis: univariate, bivariate, multivariate. What is the main goal of qualitative data analysis: to find themes and patterns in the data. What are the two main core procedures for qualitative data analysis: coding classification of phenomena, memoing. What is open coding: making sense of massive amounts of qualitative data by trying to identify as many themes, ideas and patterns as possible. What is the constant comparative method: constantly comparing each new piece of data against the codes and notes already provided. It is important to pay attention to the exact words used as each word depending on the form and word used evokes so much meaning. Therefore be as precise as possible with the words used. What is axial/focused coding: what this type of coding you are always looking at how themes are useful and how they are related, and interact with one another.
