week 8 Flashcards
1
Q
factorial design
A
- look at more than one independent variable
2
Q
factorial matrix
A
- total number of conditions to be tested in a factorial study, visualized by all possible combos of the levels of each IV
3
Q
The number of conditions in any factorial design can be determined by __________
A
multiplying the numbers in the notation system (length x width of table)
3
Q
In factorial designs, the term ________ equals the number of cells in a matrix
A
conditions
4
Q
two kinds of results in a factorial study
A
- main effects: overall influence of each IV solo, determined by the row and column means
- interactions: if variables combine to form more complex results, specific interaction caused a change (ex type of student)
5
Q
________ design is when its a mix of between and within subject designs
A
- mixed factorial
- at least one variable within and one between
6
Q
P X E factorial design
A
- between subject factorial includes subject and manipulated IV
- interaction between person and enviro
7
Q
mixed P × E factorial
A
- the P factor is between‐subjects, and the E factor is within‐subjects
8
Q
pros and cons for within and between subject designs
A
- within:
- pros: less subjects needed, increases the chance of discovering a true difference among your conditions,
- cons: not always generalizable, small subject pool, potential for order effects, carryover effects, and practice effects.
- between:
- pros: shorter
- cons: more ppl needed, individual difference
9
Q
ATI designs
A
- Aptitude‐Treatment Interaction design
- aptitude=the subject (person) variable
- treatment=manipulated, environmental variable
10
Q
multilevel, single‐factor designs using interval or ratio data and factorial designs are analyzed using _________
A
analysis of variance (ANOVA)
11
Q
simple effects analysis
A
- comparing each of the levels of one factor with each level of the other factor
