A subset of a given population.
A representation of concept in its variation of degree, varieties or occurrence.
What is a variable
Occurs when collecting more data yields little new information.
What is saturation
Any collection of data assembled for a particular purpose. It is important to know the how and when the data was collected along with the who or what they represent
What is a dataset
This was the dependent variable in Dr. Malone's dissertation
What is intermarriage
A list of all possible individuals or artifacts in a defined population
What is sampling frame
Creating a definition that specifies how an abstract concept is measured.
What is operationalization
That which is unspoken sometimes so taken for granted by those who are doing it that they do not recognize it.
What is tacit knowledge
An independent variable that is included in the analyses in order to determine whether a relationship between two variables holds true when variation in a third variable is held constant.
What is a control variable
When one variable increase while another decrease is this correlation
What is a negative correlation
This sampling technique involves a random start and then proceeds with the selection of every kth element from then onwards.
What is systematic sampling
Two ways in which we determine quality of measurement
What are reliability and validity
Entering the field, these are the two types of research participation
What are covert and overt participation
These two measures of central tendency are not meaningful for categorical variables
What are mean and median
We used this as an example of an operationalization of a concept in class
What was the 5 love languages
Participants/artifacts are purposefully chosen because they meet some sort of specific criteria.
What is purposive sampling
When several different measures are added together to create a combined score for a particular concept.
What is an index
These are the two types of probes
What are direct and indirect
The range between the 25th and 75th percentiles is called
What is the interquartile range (IQR)
Evan Welker used this concept to discuss how people overestimate their abilities
What is the Dunning Kruger Effect
These are two paradigms of sampling
What are probability and non-probability sampling
These are two of the three ways we can test for reliability
What are inter-rater(coder), inter-item, and test-retest reliability
These are the three types of interview styles
What are formally structured, semi-structured, and unstructured interviews
These values assigned to each observation and they are used to account for small discrepancies.
What are variable weights
In My Brother's Keeper, Dr. Malone used this situation to talk about his experience with racial microaggressions.
What is his colleague using the term "race card" and other deflections to get him to fall into the stereotype of the "angry Black man".
