What is Quantification analysis?
Some data is inherently numerical (eg age, number of children) other ddata can be numerically coded to be used in quantitative analyses (race, sex, political affiliation)
In relation to Quantification of Data, what are two ways to develop code categories?

What is a univariate analysis?
The analysis of a single variable for purposes of description
In relation to univariate analysis, what is a continuous variable?

In relation to univariate analysis, what is a discrete variable?
A variable whose attributes are seperate from one another such as gender or political afiliation
In relation to univariate analysis, what are Frequency Distributions?
A description of the number of times the various attributes of a variable are observed in a sample
In relation to Univariate analysis what is a central tendency?
Average- an ambigious term generally suggesting typical or normal
What is an example of a central tendency?
Mean median or mode
What is the definition of Mean?
An average computed by summing the values of several observations. Interval or ratio variables
What is the definition of the mode?
An average representing the most frequently observed value or attribute
What is the definition of Median?
An average representing the value of the middle case in a rank ordered set of observations.
What is the definition of Dispersion?
The distribution of values around some central value such as the mean, median or mode
What is Standard deviation?
A measure of dispersion around the mean calculated so that approximately 68 percent of the cases will lie within plus or minus one standard deviation from the mean. 95 percent within 2, 99.9 percent within three
In relation to Dispersion and standard deviation the curve for a small standard deviation id A) (Large/skinny)? and for a large standard deviation B) (Large/ Skinny)
A. Skinny
B. Large
What are subgroup compariasons?
Descriptions of subsets of cases subjects or respondents
What is a bivariate analysis?
The analysis of two variables simyltaneously, for the purpose of determining or explainign the empirical relationship between them
In relation to a bivariate analysis what are the two main principles to consider when constructing a Bivariate Table?
- determine the logical direction of relationship (IV DV)
2. Percentaging a table
How do you know whether to percentage down or percentage across?
That depends on te location of the IV in the table
What is a contingency table?
A format for presenting thre relationship among variables as percentage distributions
What are the 5 guidelines for presentation of tables in a Bivariate Analysis?
- A table should have a heading or title that describes what is contined in the table
- original cotent should be clearly presented
- the attributes of each variable should be clearly indicated
- The base on which percentage are computed should be indicated
- issing data should be indicated in the table
What is a multivariate analysis?
The analysis of the simultaneous relationships among several variables (explanatory)
Which of the following describes the analysis of more than two
variables?
A. experimental designs
B. quasi-experimental designs
C. qualitative evaluations
D. multivariate analysis
D.
. The process of converting data to numerical format is called \_\_\_\_\_. A. feminist research B. qualification C. quantification
C.
Which of the following are basic approaches to the coding
process?
A. You can begin with a well developed coding scheme.
B. You can generate codes from your data.
C. both of the above
D. none of the above
C. The following are basic approaches to the coding process: you can
begin with a well developing coding scheme and/or you can generate
codes from your data.
A _____ is a document that describes the locations of variables
and lists the assignments of codes to the attributes composing those
variables.
A. cross-case analysis
B. codebook
C. constant comparative method
D. monitoring study
B. A codebook is a document that describes the locations of variables
and lists the assignments of codes to the attributes composing those
variables.
The _____ is an “average” computed by summing the values of
several observations and divided by the number of observations.
A. frequency
B. mean
C. median
D. mode
B.
- Which of the following are aimed at explanation?
A. multivariate analysis
B. bivariate analysis
C. univariate analysis
D. both A and B
D. Multivariate analysis and bivariate analysis are aimed at explanation.
What is the defiition of Qualitative analysis?
The nonnumerical examination and interpertation of observations .
What is the purpose of Qualitative analysis?
Discovering underlying meanings and patterns of relationships.
Wat is a cross-case analysis?
An examination of more than one case;can be either variable or case oriented
What is variable oriented analysis?
Describes/ and or explains one or more variabels
What is a case- oriented analysis?
Aims to udnerstand a particular case or several cases by looking closely at the details of each
Grounded theory method is an ______ approach to research
Inductive
Who were the main controbutors to grounded theory method?
Barry glaser and Anselem strauss
In grounded theory method how are theories generated?
from examination of data rather than being derived deductively
________ ________ Method is a component of Grounded theory method?
Constant comparative
In constant comparative method observations are….?
Constantly compared with one another and with the evolving inductive theory
What is Semiotics?
The study of signs and the meanings associated with them
What is Conversation analysis?
A meticulous analysis of the details of conversation, based on a complete transcript that includes pauses hems and haws

summarize
What is (PRE) Proportiantite reduction of error?
- Knowing about one variable often tlls us something about other variables
sometimes it tells us a lot sometimes it tells us us relatively little
the more it tells us the greater the error is reduced
What is an example of PRE?
If we know how much education someone has we can imporve our ability to estimate how much they earn
