Linear Relationship - ANS-= type of relationship that exists between two
variables whose graphed data points lie on a straight line
Coefficient of Determination - ANS-=a measure of the amount of
variation in the dependent variable about its mean that is explained by
the regression equation
regression toward the mean - ANS-=the tendency for extremes of
unusual scores to fall back (regress) toward their average
Standard error of estimation - ANS-=In regression, the standard
deviation around the regression line or the standard deviation of
residuals
=interpreted the same way as Standard deviation
Estimation - ANS-=a rough calculation of the value, number, quantity,
or extent of something.
Regression analysis - ANS-=measures the impact of 1 set of criterion
variables on another variable
Simple Regression - ANS-=implies that we have only one prediction
variable
Multiple Regression - ANS-=when we have 2 or more predictor
variables
, Slope of regression line - ANS-=represents the change in y (response
variable) for a unit change in x (predictor variable)
Cronbach's alpha - ANS-=an indicator of internal consistency reliability
assessed by examining the average correlation of each item (question)
in a measure with every other question.
Cronbach's alpha coefficient - ANS-=average of all possible split-half
reliabilities
Relaibility - ANS-=consistency of measurement
#refers to the consistency with which it measures whatever it measures
Systematic factors - ANS-=factors that affect the average returns of a
large number of different assets
#emotional state of mind
#fatigue
#noise
Types of Reliability - ANS--Establishes the consistency and stability of
the evaluation
= exist because thy help to address a particular dimension of
consistency that might be important in a study
Test-retest reliability - ANS-=a method for determining the reliability of
a test by comparing a test taker's scores on the same test taken on
separate occasions
=administer the same test to the same group twice
Alternate forms reliability - ANS-=a procedure for testing the reliability
of responses to survey questions in which subjects' answers are
compared after the subjects have been asked slightly different versions
