T-TestTo determine whether a statistically significantdifference exists between two means
For example:Teachers identified some of their students ashaving exceptional intellectual potential. Thesestudents got significantly higher test scores thanthe rest of the class
T-Test used to find if the performance differenceis statistically significant

Analysis of Variance (ANOVA)To look for differences among three or moremeans by comparing the variances (s 2) both withinand across groups

7/87
Analysis of Variance (ANOVA)For example:
D oes the presence of other people have an influenceon whether a person will help someone in distress
In a classic study, the experimenter (a female graduatestudent) had the subject wait in a room with either 0, 2,or 4 other peopleThe experimenter announces that the study will beginshortly and walks into an adjacent roomIn a few moments the person(s) in the waiting roomhear her fall and complain of ankle painThe dependent measure is the number of seconds ittakes the subject to help the experimenter (Darley &
Latan, 1969)

8/87
Analysis of Variance (ANOVA)Study involved comparison of 3 means or a multigroup mean analysis
Differences can be due to:G roup Membership (i.e., the treatment effect or effect of being in a small vs. larger group).N ot due to group membership (i.e., chance or s ampling error ).

Type I, Type II errorsNull hypothesis > reject null (to prove
hypothesis)
The harder you study, the higher your grades are likelyto beYour grades have no relation to how hard you study
Prove null > but reject it:
Type I error: false rejection of a true null
Disprove null > but retain it:Type II error: false retention of a false null

10/87
Analysis of Covariance (ANCOVA)
Look for differences among means whilecontrolling for the effects of a variable that iscorrelated with the dependent variable (covariate)
Decreases the probability of Type II error (falseretention of a false null or prevent rejecting it)
-

11/87
Analysis of Covariance (ANCOVA)
For example: A set of 20 third-graders, randomly sorted into twoindependent groups of 10 subjects each, with thedesign of teaching one group by Method A and theother by Method B.
The aim of the initial random sorting is to ensurethat the two groups are starting out approximatelyequal , on average, with respect to all pertinent
factors.
-
8/6/2019 TEC 5143 SP11 Last Class Final Exam Review0
12/87
Analysis of Covariance (ANCOVA)
It could happen through sampling error or sheer random variabilitythat the two groups do notstart out equal with respect to one or more factors
For instance, one of the groups may start out witha higher average level of intelligence or motivation, which would surely complicate the
situation
The analysis of covariance provides a way of measuring and removing the effects of such initialsystematic differences between the samples.

Regression
To examine how efficiently one or more variablesallow you to predict the value of another (dependent) variable
A regression is a statistical analysis assessing theassociation between two variables .
Used to find the relationship between twovariables.

Regression
Simple linear regression generates anequation where a single independent
variable yields a prediction for the dependentvariableusing a macroeconomic variable such aspersonal income to forecast home ownership
Temperature to predict thirst (water consumption)

Factor Analysis
Examine the correlations among a number of variables and identify clusters of highly interrelatedvariables that reflect underlying themes or factorswithin the data
-
8/6/2019 TEC 5143 SP11 Last Class Final Exam Review0
17/87
Factor AnalysisFor example, consider the construct of "leadership" -"task skills" and "people skills"D eveloping a new questionnaire about leadership
20 items - 10 for "task" elements and 10 "people"elements,Pretest to verify validity
Factor analysis can be used to check if there are reallytwo factors, and if those factors represent thedimensions of task and people skills.If yes create two separate scales, by summing the
items on each dimension

Structural Equation Modeling (SEM)
Examine correlations among a number of variablesin order to identify possible causal relationships(paths) among them
Typically used to test a previously hypothesizedmodel of how variables are causally interrelated
-

19/87
Structural Equation Modeling (SEM)S uppose you have the list of numbers 1,2,3.These numbers have a mean of 2 and a s tandard deviation of 1
N ow, suppose you take these 3 numbers and multiplythem by 4. Then the mean would become 8, and thestandard deviation would become 4, the variance thus16
S o if you have a set of numbers X related to another setof numbers Y by the equation Y = 4X, then the varianceof Y mu s t be 16 times that of X, so you can test thehypothesis that Y and X are related by the equation Y =4X indirectly by comparing the variances of the Y and X
variables

Structural Equation Modeling (SEM)
This idea generalizes, in various ways, to severalvariables inter-related by a group of linear equations
The rules become more complex, the calculationsmore difficult, but basically:
You can test whether variables are interrelatedthrough a set of linear relationships by examiningthe variances and covariances of the variables

Meta Analysis
Analyze and draw conclusions from other researchers statistical analysis
Analysis of analysis > meta analysis
Integration of studies statistically (not descriptive)Conduct fairly extensive search for relevantstudiesIdentify appropriate studiesConverts each studies results to a common
statistical index > Effect Size
-
8/6/2019 TEC 5143 SP11 Last Class Final Exam Review0

Meta Analysis
Effect Size: how much of a difference anintervention makes ( in terms of standard deviation
units) in each study
Effect sizes for all studies used to computeaverage effect size for that intervention
