anything goes
100
The scale of measurement that is categorical with no properties of the real number system.
What is nominal data
100
To summarize data obtained from a sample, e.g. pie chart, frequency counts.
What are Descriptive Statistics?
100
Stating that the null was false when it was indeed true.
What is Type One Error?
100
The experimenter limits confounding variables within environment with the measurement tool and design.
What is Control Through Procedure?
100
To clearly define variable making it as measureable as possible.
What is Operational Definition?
200
Can only take on values that are separate (nominal & ordinal)
What is Discrete data.
200
"What" is to descriptive statistics as population is to inferential?
What is sample?
200
Lower alpha increases the chances of making this error.
What is Type Two error.
200
When the participant and data collector do know which treatment condition the participant belongs.
What is Double Blind?
200
The acceptable alpha level used in social science.
What is .05?
300
Only two categories (e.g. male-female)
What is Dichotomous
300
Determines the direction fo the study; its measures, scaling and thereby statistical analysis.
What is hypothesis?
300
The degree to which an instrument consistently measures the same variable.
What is Reliability
300
The sampling strategy used, e.g. sample of convienance, cluster, random startification.
What is Participant Selection?
300
What one does when the obtained probability is larger than alpha.
What is Accept the Null?
400
Scores that do not allow for distinction in top scores.
What is Ceiling Effect
400
When sample data is used to generalize to other samples within the population.
What are inferential statistics?
400
Changes in the dependent variable do to normal growth and development.
What is Maturation?
400
The design in which participants serve as their own controls.
What is Within Designs?
400
Necessary to ensure inter-rater reliability when data collectors are making observations.
What is Training and percent agreement.
500
When extreme scores tend to be more similar to the normal distribution upon retesting.
What is Regression to the Mean?
500
When all of the .05 alpha is in one tail of the distribution.
What is a directional hypothesis?
500
The cross contamination of an intervention to other research groups.
What is Diffusion of Treatment?
500
The design in which both within and between participants are analyzed.
What is Mixed Designs?
500
The problem with running too many analyses on the same data.
What is Inflates Alpha?
