This approach to reliability has half of the subjects taking one half of a questionnaire/test and the other half of the subjects taking the other half.
What is split half
100
This is often termed the research or experimental variable and can be manipulated by researcher
What is an independent variable
100
This type of research can be done on a phone, paper or on the internet.
What is survey method
100
This design is similar to a true experimental design but lacks randomization of subjects.
What is a quasi experimental design
100
A pearson r correlation coefficient of .78 would suggest this about two variables.
What is a strong positive correlation
200
This type of validity is simply whether the measurement appears to measure what it is intended to measure.
What is Face validity
200
This variable is not planned or controlled by the researcher but can have an unintended affect on the dependent variable
What is Confounding variable
200
Often field research involves this type of analysis and does not involve the manipulation of statistics.
What is Qualitative
200
A pre experimental design lacks this feature
What is a control group
200
This is the square root of the variance
What is a standard deviation
300
This type of validity reflects whether the instrument completely and fully measures the concept or construct that it intends to measure.
What is content validity
300
This variable is what is being measured to see what effect the researching variable has had.
What is a dependent variable
300
In this type of design the goal is to determine the relationship between 2 or more variables
What is correlational
300
Experimental designs can be utilized to determine a _________ relationship
What is causal
300
The Mean, Mode and Median are measures of this
What is Central tendency
400
This reflects the ability of an instrument to measure consistently between different individuals who are making observations.
What is inter-rater reliability
400
This design examines many dependent variables
What is a multi-variant design
400
If a researchers was trying to evaluate and investigate a famous speech of Abraham Lincoln to determine the amount of biblical references they would be using this non experimental approach
What is content analysis
400
A true experimental design must have these two components.
What is a control group and randomization
400
This score describes the distance in standard deviations it is from the mean
What is a z score
500
This type of validity measures the instrument against other already established instruments to determine its accuracy.
What is criterion validity
500
This type of variable is one with a well defined finite set of possible values
What is a discrete variable
500
This type of research method provides a detailed, in-depth description of everyday life and practice or culture.
What is Ethonography
500
Experiments need this to help increase the reliability of the results
What is replication
500
This is the core theorem in the world of inferential statistics
