This statistic's formula, the average of the squared differences from the mean, describes how far a set of numbers is spread out.
What is variance
100
This statistical test can describe the tendency for two sets of data to vary consistently, but it may not equal causation.
What is correlation?
100
It's no accident; this type of sampling intentionally selects individuals and sites to learn or understand a central phenomenon.
What is purposeful sampling
100
Any way you slice it, this survey design involves data collection at one point in time.
What is a cross-sectional survey design?
100
This type of mixed-methods design utilizes the simultaneous collection of both quantitative and qualitative data, as well as the merging of that data, to understand a research problem.
What is a convergent mixed methods design?
200
When analyzing this statistic, a low one indicates data points that are close to the mean, while a high one indicates data points that are spread out farther from the mean
What is standard deviation?
200
This type of sampling helps to make groups comparable by selecting people with similar personal characteristics.
What is homogeneous sampling?
200
This grouping of similar codes forms a major idea in the data, and make up a core element in qualitative data analysis.
What is a theme?
200
Educators seek to enhance the practice of education through the systematic study of a local problem using this type of research.
What is practical action research?
200
This design consists of first collecting quantitative data, and then collecting qualitative data to help explain or elaborate the quantitative results.
What is an explanatory sequential mixed methods design?
300
Using this type of scale, numbers represent different categories that are assigned without any rank or order.
What is a nominal scale?
300
This type of experimental design meets all the requirements of a true experiment, except that groups are not randomly assigned.
What is a quasi-experiment?
300
Researchers use this technique to corroborate evidence from different individuals, types of data, or methods of data collection in descriptions and themes to verify accuracy and credibility in research.
What is triangulation?
300
The concept of a researcher examining his or her own practices, rather than someone else's, is known as this type of research.
What is self-reflective research?
300
This design is the opposite of the explanatory model, gathering qualitative data first, and using quantitative data to explain relationships discovered in the qualitative data.
What is an exploratory sequential mixed methods design?
400
This "M" statistic represents the middle number in a population or sample.
What is median?
400
These problems leading to difficulty inferring whether a covariation between treatment and outcome is causal can include history, maturation, or regression.
What are threats to internal validity?
400
Keep your head out of the clouds if you want to utilize this qualitative design, a systematic procedure used to explain, at a broad conceptual level, a process or action about a substantive topic.
What is grounded theory design?
400
This systematic process of collecting and analyzing information about the efficiency, effectiveness, and impact of services is a type of action research.
What is program evaluation?
400
A research must consider this when deciding how much weight one type of data will have over the other in a mixed-methods design.
What is priority?
500
Don't sleep on this statistic, which measures a number's relationship to the mean in a group, and can be positive or negative.
What is a Z-score?
500
When examining a scatterplot, points that move in the same direction share this type of correlation; I'm sure of it.
What is a positive correlation?
500
This design is made up of procedures for describing, analyzing, and interpreting a culture-sharing group's shared patterns of behavior, beliefs, and language that develop over time.
What is ethnographic design?
500
This "ended" question provides options to select from, and allows for more convenient response comparison.
What is a closed-ended question?
500
I can see it now; researchers often use this to help readers identify the sequence of data collection in a mixed-methods design.
