Term
Samples
Definition
this represents the entire population
Term
Sample Frame
Definition
The people who could conceivably be in a sample
Term
Random Sample
Definition
when everyone has the exact same chance of being sampled
Term
Simple Sampling
Definition
Form of random sampling when every single person or unit in your population has the exact same chance of being sampled
Term
Systematic Sampling
Definition
Form of random sampling putting people in some order, then choosing every kth person
Term
Stratified sampling
Definition
Form of random sampling when you divide your sampling frame into meaningful categories, then randomly sample
Term
Proportional Sampling
Definition
Divide your sampling frame into meaningful categories, then randomly sample from those categories according to their occurrence in the population
Term
Cluster Sampling
Definition
Divide your sampling frame according to clusters, then randomly choose clusters. YOU DO NOT SAMPLE INDIVIDUAL PEOPLE
Term
Non Random Sampling
Definition
This type of sampling is not representative of a population
Term
Convenience
Definition
Occurs when you are sampling people who are nearby or readily available
Term
Volunteer
Definition
Occurs when you are sampling people who are willing to participate. OFTEN MISTAKEN WITH RANDOM SAMPLING!
Term
Sample Power
Definition
The overall probability that your research will identify a statistical effect when it occurs
Term
Confidence Level
Definition
The probability that your measurement is correct
Term
Margin Error
Definition
The probability that your measurement is correct
Term
Census
Definition
If you study an entire Population you are conducting a
Term
Parameters
Definition
Any math you do with the population data is called _____
Term
Statistics
Definition
Any math you do with the small group data is called _____
Term
Content Analysis
Definition
Any systematic procedure devised to examine the content of recorded information. You are counting the amount of times something happens.
Term
Codesheet
Definition
set of codes that researchers use to identify whether something “is” or “is not”
Term
Exhaustive
Definition
If all options for content are included
Term
Mutually Exhaustive
Definition
If no options for content overlap
Term
Codebook
Definition
The very detailed and specific operational definitions researchers must follow when using the codesheet
Term
A Priori Coding
Definition
First, decide what you want to look for in the content,
based on theory and previous literature. Then, code or what you expect based on theory. (PREFERRED)
Term
Emergent Coding
Definition
First, read units of analysis to get a “feel” for what
could be there. then, code for what you expect based on gut feeling.
Term
Systematic quality of content analysis
Definition
follows specific rules
Term
Operational quality of content analysis
Definition
Replicable. Different researchers using the same coding instruments would get the same results
Term
Quantitative quality of content analysis
Definition
Shown in numbers. Content tends to be qualitative, but we can categorize it and identify quantitative patterns
Term
Manifest Content quality of content analysis
Definition
Coding only what is present
Term
Latent Content quality of content analysis
Definition
Room for interpretation when coding
Term
Unit of Measurement
Definition
Act we are counting
Term
Unit of analysis
Definition
Context of that act
Term
Sampling Units
Definition
Broadest definition of our units of analysis. (Episodes)
Term
Recording Units
Definition
More specific definition of our units of analysis (Individual Units of action)
Term
Context Units
Definition
Content or contextual features that may appear in an individual recording unit. (number of acts per interaction)
Term
Intercoder Reliability
Definition
Multiple coders agree about the proper categories each unit of analysis fits into. (ESSENTIAL FOR CONTENT ANALYSIS)
