What is the research?
100
This is the average of all scores.
What is the mean
100
This is the consistency of scores.
What is reliability?
200
Measurement requires this to be differentiated.
What is variables?
200
This is the score in the middle of the distribution.
What is the median

What is Stability?
300
There are 4 basic ways that measure difference.
What is the scales of measurement?
300
This is the simplest type of frequency distribution.
What is a frequency table?
300
Measurement has a great amount of error if this is low.
What is reliability?
400
Ratios used to compare and interpret the scores.
What is the ratio scale?
400
This is a graphic frequency distribution.
What is a frequency polygon?
400
If measurement has a high reliability then there is little of this in the scores.
What is error?
500
This scale of measurement is usually used in educational research. Categories are rank-ordered.
What is the ordinal scale?
500
This is the average distance of the scores from the mean.
What is the standard deviation?
500
This is the extent to which inferences are appropriate and meaningful.
What is validity?
