This statistical test produces values that range between -1 and 1.
What is a correlation
100
This type of validity is focused on being able to generalize the results
What is external validity
100
When deemed necessary, a researcher can use this on a participant ONLY if it does not cause physical or psychological harm.
What is deception
100
This is any variable other than the IV that might cause a relationship between variables
What is a confounding variable
100
This is the type of hypothesis which states that the results are expected to not differ from chance.
What is the null
200
This is another name for the line of best fit
What is a regression line
200
The only way you can infer causation is if you use this research design.
What is experimental
200
What scales shows equal distance between the values and represents equal change in the conceptual variable?
What is an interval scale
200
This type of quantitative variable can be divided into infinitely smaller units
What is a continuous variable
200
This is the statement that turns a conceptual variable into a measurable variable
What is an operational definition
300
Correlational research must contain this visual representation.
What is a scatterplot
300
These are the two different types of knowledge in Research Design
What is descriptive and predictive knowledge
300
Deception is one way of reducing this.
What is reactivity
300
This must be manipulated by the researcher and is the variable to which we want to attribute effect
What is the causal variable (or independent variable)
300
We have made this type of error when we reject a true null hypothesis.
What is Type I error
400
These are the three qualities tested by correlations
What is linearity, strength, and direction
400
The extent to which a measure is free from random error
What is reliability
400
A good research hypothesis contains these two qualities
What is testability and falsifiability
400
When determining what is being studied, this type of variable is the abstract concept being studied that can't be directly measured or observed
What is a conceptual variable
400
Temporal proximity, association, control of common causal variable are the three requirements for demonstrating this.
What is causality
500
This is the between group variance divided by within group variance equals this statistic.
What is the "F" statistic or the ANOVA statistic
500
These are the four types of validity
What are external, internal, measurement, and statistical conclusions
500
This is the term for using more than one technique, method, procedure, or population to study a similar topic.
What is converging operations
500
Using participants that are all 15 years old would be an example of this
What is a control constant
500
This type of error when determining the null hypothesis to be retained or rejected occurs when there is a miscalculation or there is not a large enough sample size
