/.Regression Equation - Answer-y = bX + a
/.Multiple Regression - Answer-Uses scores on one variable (the predictor) to predict
changes in another variable (the criterion)
/.Squared correlation coefficient [r^2] - Answer-The amount of shared variance
- The % of variance in one variable accounted for by the second variable
/.r value indicates a [Medium] effect/covariation - Answer-0.30
/.r value indicates a [large] effect/covariation - Answer->0.40
/.r value indicates a [small] effect/variation - Answer-0.10 - 0.20
/.Scatterplot - Answer-Each pair of scores from a correlation is plotted as a single point
on a graph
/.Cohen's d = 1 - Answer-The means are separated by 1 standard deviation
/.Cohen's d - Answer-Describes the magnitude of the effect of the IV on the DV

/.% of scores fall within 2 SD - Answer-95%
/.% of scores fall within 1 SD - Answer-68%
/.Variability - Answer-The spread in a distribution of scores
/.Mean as most useful measure of central tendency - Answer-It maximises the use of all
data
,- Can use in statistical analysis
/.Value of central tendency to use when you have [nominal or ordinal variables] -
Answer-Mode
/.Value of central tendency to use when [outliers] - Answer-Median
/.Structural equation modelling - Answer-SEM examines models that specify a set of
relationships among many variables
/.Yes/No is IV x PV true experimental design - Answer-No
- Participant variables are not randomly assigned or controlled
/.Statistical analysis to assess the unique contribution of each variable in a correlation -
Answer-Multiple Regression
/.Discriminant validity - Answer-Is the measure not related to what it shouldn't relate to?
- The measure should be able to discriminate between the construct being measured
and other unrelated constructs
/.Internal consistency reliability - Answer-Assesses how well a certain set of items relate
to one another
- Is a participants score on this construct similar across items that are aimed to measure
related aspects of the construct
/.Quality that single case experiments lack - Answer-Generalizability
/.Setting that true experiments generally harder to perform - Answer-In applied settings

being observed

ratio
/.What an animal care committed is composed of - Answer-1 scientist with experience in
animal use
1 institutional member who does not use animals
1 experienced vet and a community member
/.Multiple baseline: Across situations - Answer-Same behaviour is measured in different
settings
, /.Multiple baseline: Across Behaviours - Answer-Several different behaviours of a
participant are measured over time
/.Multiple baseline: Across participants - Answer-The behaviour of several participants is
measured over time
/.Ethical problem associated with reversal designs - Answer-You cannot ethically take
people (medical patients) off treatment that is working
/.Reversal design (setup) - Answer-ABA
(A) Baseline > (B) Treatment > (A) Baseline
/.Evidence that the manipulation was effective in a single case experiment - Answer-A
change in the participants' behaviour from the baseline to treatment periods
/.5 steps in performing a program evaluation - Answer-1 > Needs assessment

council policy statement
/.Mixed Factorial Design - Answer-A mix of independent measures and repeated
measures
/.Main flaw in cross-sectional designs - Answer-Differences may be due to cohort
effects
You can't assume the next generation will look the same
/.Just research - Answer-Treat people fairly + equitably by distributing the benefits and
burdens of the research
/.Concern for welfare in research - Answer-Attempt to minimize risk
And maximize benefit
/.Show respect for person in research - Answer-??
/.3 Basic ethical principles - Answer-1 Respect for persons
