This is what you get when you take the square root of a populations variance. Often depicted with the symbol "S"
What is the standard deviation
100
A form of quantitative research, this design seeks to describe trends in a large population of individuals and usually involves the administration of some sort of questionnaire to a small group in order to identify trends of a larger group.
What is Survey Design
100
This type of statement serves to advance the overall direction or focus for a researcher's study
What is a Purpose Statement
100
In this type of sampling is the most rigorous form of quantitative research, and involves the researcher selecting individuals from a population who are representative of that population.
What is Probability Sampling
100
This is the total of scores divided by the number of scores. Often uses the symbol "M"
What is the Mean
200
The closer the dots are on this particular chart indicates a strong correlational relationship between 2 variables
What is a scatter diagram
200
Also referred to as "intervention studies", this is a quantitative research design in which the investigator determines whether an activity or materials make a difference in results for participants.
What is experimental design
200
This statement in quantitative research in which the investigator makes a prediction or a conjecture about the outcome of a relationship among attributes or characteristics
What is a Hypothesis
200
A form of probability sampling, this type of sampling requires researcher to select participants that have an equal probability of being selected from the population.
What is Simple Random Sampling
200
This is the middle score among all scores. It divides rank-ordered scores in half.
What is the Median
300
This is the average of the cross products of Z scores and often represented with the symbol "r"
What is the correlation coefficient
300
These type of designs are a systematic, qualitative procedures that researchers use to generate a general explanation that explains a process, action, or interaction among people.
What are Grounded Theory Designs
300
This is an attribute or characteristic within one's research that is influenced by the independent variable
What is the Dependent Variable
300
In this type of sampling, the researcher chooses very Nth individual in a population until they reach a desired sample size.
What is Systematic Sampling.
300
This describes the score that appears most frequently in a list of scores.
What is the Mode
400
If scores from an instrument are stable and consistent, the instrument is said to have this.
What is Reliability
400
In type of qualitative design uses procedures to describe, analyze, and interpret a cultural group's shared patterns of beliefs, behaviors, and language that develop over time.
What is Ethnographic Design
400
In research, this is an attribute or characteristic that influences or effects an outcome.
What is the Independent Variable.
400
A type of probability sampling in which researchers divide the population on some specific characteristic, and then uses simple random sampling to sample each subgroup of the population
What is Stratified Sampling
400
This indicates the dispersion of scores around the mean.
What is the Variance
500
This is the relationship between 2 variables in which high scores on one go with low scores on the other, medium scores are with the other medium scores, but the low scores correspond with the other's high scores.
What is a negative correlation
500
in this form of quantitative design, investigators seek to measure the degree of association (or relation) between two or more variables using statistical procedures.
What is Correlational Design
500
This is a type of independent variable that researchers measure for the purposes of eliminating it as a possibility, but it is not a central variable of concern in explaining the dependent variable or outcomes.
What is the control variable
500
Type of sampling in which a researcher asks participants to identify others to become members of the sample.
What is Snowball Sampling
500
This is a popular form of standardized scoring that has a mean of 0 and a standard deviation of 1.
