reliability and validity
Levels of Measurement
Descriptive Stats
Surprise
100
This is the action or intervention variable that causes change in the other
What is the Independent Variable?
100
When findings can be applied beyond the specific study settings and applied to different situations or populations
What is External Validity?
100
This level of measurement only has categories either dichotomous or categorical
What is the nominal level?
100
The most frequently occurring value or attribute
What is the mode?
100
this statistic shows the amount of probability that the results were caused by chance
What is the p value or statistic?
200
This design has one control and one intervention group and uses random sampling
What is the Classic Experimental Design?
200
When we are sure that the changes in the dependent variable are caused by the independent variable
What is internal validity?
200
Examples of this level of measurement are money and age
What is Ratio level of measurement?
200
The only way to summarize or describe nominal data
What are frequencies?
200
The idea that participation in research should be voluntary and the subject should know what they are getting themselves into
What is informed consent?
300
gender, age, scores on a scale are samples of this aspect of variables
What are values?
300
When more than one rater measure the same observations and get very similar results
What is inter-rater reliability?
300
Examples of this measure are IQ and Farenheit
What is Interval level of measurement
300
The descriptive statistic that shows how far away from the mean individual scores are located (on average) for a sample or for a population
What is the standard deviation?
300
The process in which practitioners use the best scientific evidence to inform their practice
What is Evidence Based Practice
400
positive and negative are descriptors of this
What are relationships between independent and dependent variables?
400
history and instrumentation are samples of this
What are threats to internal validity?
400
This level of measurement is often used on a rating scale where 1 is least and 5 is most
What is ordinal level of measurement?
400
What we are seeing when the mean median and mode are the same
What is a symetrical distribution or a bell curve?
400
This is where each element has an equal chance of selection
Random selection?
500
The statistic that measures internal validity by measuring half the items of a test to the other half
What is Cronbach Alpha?
500
This threat to validity would happen if Channing Tatum gave you your final exam instead of your professor
What is research reactivity?
500
Case studies and focus groups are example of this
What is Qualitative Research?
500
These statistics should only be calculated on interval and ratio data
What are medians, means and standard deviations?
500
This type of design: 01 02 03 04 05 X 06 07 08 09 010
What is Time series design (quasi-experimental)?
