validity: tends to provide measures with greater validity than do survey and experimental measurements
reliability: often very personal (not reliable)
Term
Content Analysis
Definition
Study of recorded human communication (magazines, tv shows, magazines, websites, newspapers, emails, etc. Need to carefully define your unit of analysis (ex. writers vs. types of books), which drives your sampling strategy (all books by a certain author vs. type of book/by multiple authors)
Term
Coding
Definition
can choose to code manifest content (visible, surface content) or latent content (underlying meaning)
Term
Strengths of Content Analysis
Definition
economical, allows for correction of errors, permits study of processes over time, minimal opportunity for researcher to have effect on subject studied, concreteness of documents results in high reliability.
Term
Weakness of CA
Definition
limited to recorded communications
Term
Analyzing existing stats
Definition
Gallup surveys, Statistical Abstract of the US.
Term
potential validity issues with analyzing existing stats
Definition
limited to available stats (see Durkheim example below); stats represent groups within the population - often don’t cover exactly what we’re interested in.
Term
potential reliability issues with analyzing existing stats
Definition
accuracy of data (ex. pressure on local enforcement – as well as recordkeeping practices - impacts what crime stats are tracked/recorded. Also, certain crimes are underreported).
Term
Comparitive & historical research
Definition
Uses historical methods to examine societies over time and in comparison with one another. Often informed by a particular theoretical paradigm.

*

Ex. Weber’s study of religion institutions as sources of social behavior (ie, degree to which religion set foundation for capitalistic economies)
Term
Weber's study of religion:
Definition
By reviewing official church doctrinal documents, Weber found that Protestant/Calvinist religious teaching emphasized the accumulation and reinforcement of capital, whereas religions in China and India (as well as Judaism) did not - which is why, Weber reasoned, capitalism did not develop in the ancient cultures of China, India, and Israel.
Term
Comparitive & historical analytic techniques
Definition
Researcher must be able to find patterns amongst voluminous amounts of data using conceptual models of social phenomena. For example, Weber studied bureaucracy to understand the essentials of bureaucratic operation.
Term
Comparitive and historical research validity concern
Definition
Cannot assume that history as documented fully coincides with what actually happened. Also need to be aware of the biases in the data (do they represent primarily the views of a particular group of people – ie, wealthy, poor, etc.)
Term
experiment v. observation
Definition
*

Goal of experiments is to isolate the cause/effect relationship, actual interaction events may be greatly simplified in the interest of experimental control.
*

With observation, primary research focus is on details of the interaction events.
Term
self-report v. observation
Definition
*

Observation focused on perspective of third-party perspective, while self-reports generated from participant’s own perspective.
*

Self reports also tend to measure more global aspects of behavior (self-reports report on more specific items); self-reports confound what people actually do with what they think they do; self-reports are more subjective, selective and thematic.
Term
Advantages of natural events (v. staged)
Definition
Naturalistic observation provides realism, and allows participants to more quickly habituate to presence of observer since context is already familiar and hence focuses their attention (thereby diminishing effect of researcher’s presence).
Term
disadvanatages of natural events (v. staged)
Definition
*

Range of situations that can be observed naturally is limited due to privacy issue.
*

“Houseguest effect”- participants may be on their best behavior (more positive, less conflict).
*

Lack of standardization across observed situations makes comparison across samples difficult.
*

Hard to combine naturalistic observation with self-reports.
Term
advantages of staged events
Definition
role plays, games, conflict-generating tasks are more precise than natural events at eliciting the behavior of interest.
Term
disads of staged events
Definition
cause people to disagree about things they wouldn’t, and they may be more or less expressive than normal. One solution is to have people discuss issues that occur in their own relationships.
Term
sampling
Definition
Tend to use convenience samples which over represents white, middle class, college-educated people. Self-selection bias (people who choose to participate) adds to this issue – Babee recommends quota sampling as one solution.
Term
sampling behavior
Definition
*

Behaviors exhibited during study affected by size and diversity of sample. It is helpful to increase observation time to address this concern (but then can end up with overwhelming amount of data).
*

Participant reactivity is also an issue – ie, degree to which participants will put forth socially-desirable behavior or be more inhibited because of observation. These tendencies are difficult for participants to sustain over time, though.
*

Also, behaviors sampled tend to neglect the brief, unfocused, and variable encounters that dominate daily interaction.
Term
Quantification of data
Definition
the numerical representation and manipulation of observations for the purpose of describing and explaining the phenomena that those observations reflect)

1. Some data, such as age and income, are intrinsically numerical

2. Often quantification involves coding into categories that are then given numerical representations

a. Example “Student Concerns”

i. Advisors suck, tuition too high, not enough parking spaces, etc..

ii. These concerns can be categorized into Academic, Administrative, & Facilities
Term
Codebook

Term
Codebook functons
Definition
1. Primary guide in coding process

a. Guide for locating variables & interpreting codes during analysis
Term
Univariate analysis
Definition

a. Example: gender, we would look @ how many of the subjects were men & how many were women.
Term
Frequency distributioni
Definition
description of the number of times the various attributes of a variable are observed in a sample

i. The report that 53% of a sample were men, & 47% were female is and example of frequency distribution
Term
Central tendency
Definition
ambiguous term generally suggesting typical or normal measures (average, mean, mode, median)
Term
average
Definition
data can be represented in the form of an average to measure your central tendency. The mean, median and mode are all specific examples of mathematical averages
Term
mean
Definition
Sum of Values/ total number of cases (n)

a. Example GPA
Term
mode
Definition
most occurring
Term
median
Definition
average representing the value of the middle case in a rank ordered set of observations.

a. Example: Ages of 5 men are: 16, 17, 20, 54, and 88 the median would be 20.
Term
Dispersion
Definition
the distribution of values around some central value, such as an average. The range is a simple example of a measure of dispersion.

i. Example: The mean age of a group is 37.9 and the range is from 12-89.
Term
Standard Deviation
Definition
more sophisticated measure of dispersion. Measure of dispersion around the mean, calculated so that approximately 68% of the cases will lie w/i plus of minus 1 standard deviation from the mean, 95% will lie w/i 2 standard deviations, and 99.9% will lie w/i 3 standard deviations
Term
Continuous variables
Definition
a variable whose attributes form a steady progression, such as age or income. Example: group of people 21, 22, 23, 24 and so forth could be broken down into fractions of years.
Term
discrete
Definition
a variable whose attributes are separate from one another, or discontinuous, as in the case of gender, religious affiliation, military rank and year in college. No progression from male to female in the case of gender.
Term
Subgroup comparisons
Definition
subgroup comparisons can be used to describe similarities and differences among subgroups with respect to some variable

1. Babbies’ tips: collapse response categories in tables. Basically he is saying there are better ways to construct your tables to avoid reading into things too much or the wrong way.

2. Handling “Don’t Knows” or “No Opinion” basically take these out of your sample data when you conduct analysis. It will give you a more accurate pic of what is going on
Term
Bivariate analysis
Definition
the analysis of two variables simultaneously, for the purpose of determining the empirical relationship between them. Construction of a simple percentage table or the computation of a simple correlation coefficient are examples of bivariate analysis.
Term
Contingency tables
Definition
the results of bivariate analyses often are presented in the form of contingency tables, which are constructed to reveal the effects of the independent variable on the dependent variable
Term
multivariate analysis
Definition
the analysis of the simultaneous relationships among several variables. Examining simultaneously the effects of age, gender, and social class on religiosity would be an example of multivariate analysis.
Term
sociological diagnostics
Definition
the analysis of the simultaneous relationships among several variables. Examining simultaneously the effects of age, gender, and social class on religiosity would be an example of multivariate analysis.
Term
ethics and quantitative analysis
Definition
ou should present an un-biased analysis…

*

if your study does not produce statistical significance, you should report the lack of correlation.
*

Do not hark.
*

Protect privacy of subjects just as you would in qualitative analysis.
