credibility & transferability
Term
How is credibility improved
Definition
by employing multiple methods & triangulating data from different sources. criticized for non-strigent can be bias.

series of behaviors(oberv) across some period ot time; try to correlate w/something else;significant effects across time; germany:suicide&economy
Term
Single designs vs group designs
Definition
focus on indiv performance, different conditions(at least 2)w/in 1 partipant. Alternative conditions to a part at different pts in time; b4 & after TX (medicine,strategy)
Term
Baseline phase
Definition
begins w/ observ of an indiv behavior b4 the tx is introduced; describes indiv of target behavior as it naturally occurs; predicts future behav. if intervention is not provided. Will behavior be maintained a stable way? several possiblities
Term
ABA single case design
Definition
A=baseline; b=treatment;
Term
Things to know about B in ABA design
Definition
Treatment; combine TX alternating w/baseline ABA, ABAB, may be permanent effect (possibly seen in next baseline) 1 IV=B multible -ABAC;ACAB to decrease carryover
Term
Replication of single-case design
Definition
repet. w/very same conditions; same effect w/2 or more part.,may conclude that intervention is effective w/a variety of indiv (external valdity)
Term
Visual inspection
Definition
intuitive;problem of reliability; visually analyzed; trend lines;interrupted time-series analysis; find the line that best describes a series of observations (data)
Term
Trend lines
Definition
tendency of a particular behavior (use mathematical formula to figure out)
Term
Trend lines
Definition
tendency of a particular behavior (use mathematical formula to figure out)
Term
Interrupted times-series analysis
Definition
phenomenon/behavior across time
Term
Multiple baselines
Definition
Experimental Tx can be introduced several times,statistical analysis can be intro.-comprare A w/B (fundamental analysis)
Term
3 possiblities of multiple baselines
Definition
Different behav for 1 particp. observed in 1 setting; different parti. in 1 setting w/diff behaviors (repeat with 2nd indiv); different settings w/one participant & 1 behav. (in different conditions)
Term
Changing criterion
Definition
intervention B is dividiend into subphases-A-B1-B2-B3; change baseline/criterion every min,3 min, 5 etc
Term
Simultaneous treatment
Definition
compare effects of alt Txs on a DV- to see what is more powerful; TX on differen alternations 1-2, 2-1 next day
Term
An alternative design is used when
Definition
causality is not central to the research purpose. Provides a lot if info.
Term
What are the 6 types of alternative designs
Definition
Case studies;ethnographic research; historical research, correlational research; survey research
Term
Historical research
Definition
collects data for analysis from existing records. not collecting data, history of condition
Term
Correlational research
Definition
relationship btw 2 or more variables, Magnitude & direction of relationships; does not mean causality but a relationship.
Term
Developmental research
Definition
development over a long period of time; describing observing reporting bhv across time
Term
Survey research
Definition
describes attitudes, beliefs, or behav of a particular pop. Finds attitudes or point of view.

r squared (shared variance) commonality existing btw 2 variables
Term
Factor analysis (correlational)
Definition

Definition
Maturation; history-things may be chged
generational(cohort effect)
Term
Generational (cohort) effect
Definition
Compare different age groups or historical events and experiences are different
Term
Longitudinal Study
Definition
Following same subjects across time; repeating testing w/same people. Problem is attrition (kids move)
Term
Cross-sectional study
Definition
Different pop (kids who are 1,2,3) not the same kids; validity isn't the same
Term
Semi-longitudinal research
Definition
2 or more groups who represent diff pts on the develop continuum; follows for some time (ie 1 yr); combine longitudanal & cross-sectional
Term
Different methods of survey research designs
Definition
random & stratified
Term
Stratified sampling
Definition
selecting people according to characteristics
Term
Replication designs and types
Definition
repeatable; direct replication-as little as possible is changed; systematic replication-1 aspect changed Men instead of women; conceptual replication-same question different variables
Term
hypotheses
Definition
statements that describes the proposed relationship btw 2 or more variables
Term
descriptive statistics
Definition
describes the characteristics of the data (mean, sd, ranges)
Term
Inferential statistics
Definition
conclusions about the significance of the data-how sign are the associations.
Term
Type 1 probability error
Definition
H0 is wrongly rejectd. False positive. says differences when there is not.
Term
Type II probability error
Definition
h0 is not rejected when is should be. False negative. there are differences. Sample size too small
Term
Power of the test
Definition
probablity of rejectin h0 when it is false
Term
What tests measure Nominal
Definition
chi-square
Term
Test for Ordinal Measure

sign test (unusual)
Term
Tests for interval & Ratio
Definition
t-test(most popular), f-ratio-t squared =F; ANOVA:calculating F (type of ratio) dif DVs, simultaneously using f-ratios
Term
Non-parametric statistics
Definition
no normal distribution-gender-nomianl values use chi-square
Term
Parametric statistics
Definition
normal distribution of scores is assumed - t test (most important)
Term
Distribution of a sample statistics
Definition
Unlikely multiple samples will have the same mean & SD. SD of a sample mean is known as standard error of the mean.
Term
3 things about the central limit theorem
Definition
1M of sampling dist= M of pop;2 variance of samp dist= pop var/N of samples; 3 pop is normal - sample dist is norm. If pop is not normal, the sampling dist will increasing approx a normal dist.
Term
Dependent t-test (related sample t-test)
Definition
2 possibilities; tests H0 that the means of 2 variables in 1 pop sample are equal. ex 2 variables/same particpants; 2 txs/1group
Term
Independent (unrelated) samples t-test
Definition
Tests the h0 that the data from test variable is = in 2 independent groups. 1 variable 2 groups; w/in subject or btw subjects design
