GRADED A+
⩥ Absolute Risk Reduction (ARR). Answer: The difference between the
absolute risk in one group (e.g., those exposed to an intervention) and
the absolute risk in another group (e.g., those not exposed).
⩥ Alpha. Answer: (1) In test of statistical significance, the significance
criterion the risk the researcher is willing to accept of making a Type I
error (false positive); (2) in assessments of the internal consistency of a
scale, a reliability coefficient, Cronbach's alpha.
⩥ Analysis of Covariance (ANCOVA). Answer: A statistical procedure
used to test mean differences among groups on an outcome variable,
while controlling for one or more covariates
⩥ Analysis of Variance (ANOVA). Answer: A statistical procedure for
testing mean differences among three or more groups by comparing
variability between groups to variability within groups, yielding an F
ratio statistic
, ⩥ central tendency. Answer: a statistical index of the "typicalness" of a
set of scores, derived from the center of the score distribution; indices of
central tendency include the mode, median, and mean.
⩥ Chi-square test. Answer: a statistical test used in various contexts,
most often to assess differences in proportions; symbolized as X2
⩥ coefficient alpha. Answer: The most widely used index of internal
consistency that indicates the degree to which the items on a multi-item
scale are measuring the same underlying construct; also referred to as
Cronbach's alpha.
⩥ Confidence Interval (CI). Answer: The range of values within which a
population parameter is estimated to lie, at a specified probability. (ex:
95%)
⩥ continous variable. Answer: a variable that can take on an infinite
range of values along a specified continuum (eg. height); less strictly, a
variable measured on an interval or ratio scale.
⩥ Correlation. Answer: a bond or association between variables, with
variation in one variable systematically related to variation in another.
⩥ correlation coefficient. Answer: an index summarizing the degree of
relationship between variables, typically ranging from +1.00 (a perfect
