This measure of central tendency is calculated by finding the sum of every number in a data set, and dividing that sum by the number of numbers in the set, or N.
What is the Mean?
100
This type of variable is an attribute or characteristic that is influenced by the independent variable.
What is a dependent variable?
100
These types of designs compare two or more groups.
What are between group designs?
100
This design can be used when researchers wish to generate a theory because existing theories do not adequately address a question. It aims to explain at a broad conceptual level a process or interaction.
What is a grounded theory design?
100
This scale of measurement is often referred to as categorical because numbers are assigned to, and used to represent categories such as gender and ethnicity.
What is nominal data?
200
This descriptive tool tells us how spread apart the numbers in a data set are and is calculated by subtracting the smallest number in the set from the largest number.
What is the Range?
200
This type of variable influences or affects an outcome or dependent variable.
What is an independent variable?
200
This design in the most rigorous form of experimental design and utilizes random assignment
What is a true experiment?
200
This design is used to describe and analyze common patterns of behavior, beliefs and languages among cultures as they develop over time.
What is ethnographic research?
200
This scale of measurement orders or ranks data, but does not indicate the degree of difference between them.
What is ordinal data?
300
The standard deviation is the square root of this.
What is the Variance?
300
This type of independent variable is neutralized through statistical or experimental design procedures.
What is a control variable?
300
This type of between group design utilizes groups that are already intact rather than creating groups by random assignment.
What is a quasi experiment?
300
This type of design collects and tells stories about peoples' lives and personal and social experiences and is used to describe the lives of individuals.
What is narrative research?
300
This scale orders data with equal intervals between items, but does not have an absolute zero.
What is interval data?
400
In a normal distribution, approximately 68 % of scores fall within plus or minus one of these from the Mean.
What is a Standard Deviation?
400
This type of independent variable is one that is manipulated by a researcher.
What is a treatment variable?
400
These types of experimental designs are used when participants are limited and researchers study a single group.
What are within group or individual designs?
400
This type of design combines qualitative and quantitative procedures in a single study in order to better understand a research problem.
What is a mixed methods design?
400
This scale of measurement orders data with equal intervals between data and has an absolute zero.
What is ratio data?
500
This number tells us how many standard deviations away from the Mean a data point is.
What is a Z score?
500
This type of independent variable combines with another independent variable to influence or affect the dependent variable.
What is a moderating variable?
500
In this type of within group design, a researcher studies one group over time with multiple pre and post test measures.
What is a times series design?
500
This step in the narrative research process involves the remapping of a story in the researcher's own words in order to place it in chronological sequence and organize key elements.
What is restorying?
500
In this type of distribution, outliers pull the mean towards a higher score.
