Front 1

hypotheses

Back 1

specific propositions that follow logically from a theory

Front 2

deduction

Back 2

process of reasoning from a general proposition to specific implications of that theory
(deriving from existing theory)

Front 3

induction

Back 3

abstracting a hypothesis from a collection of facts
(collecting info to allow you to form a hypothesis)

Front 4

falsifiable

Back 4

potential to be found false

Front 5

quasi-experimental research

Back 5

use when not able to vary the independent variable
study effects of some variable or event that naturally occurs

Front 6

identity

Back 6

each number has a particular meaning

Front 7

magnitude

Back 7

numbers have an inherent order from smaller to larger

Front 8

true zero

Back 8

zero represents a zero level of the variable being measured

Front 9

nomaial scales

Back 9

lowest level of measurment
least match their number system
naming scales, only property is identity
chi square
categorical data

Front 10

ordinal scales

Back 10

measure variables in order of magnitude
do not tell anything about difference in categories
ordered data

Front 11

interval scales

Back 11

properties of ordinal scales + equal intervals b/w consecutive values on scales
come close to matching number system but no true zero
score data

Front 12

ratio scale

Back 12

properties of identiy, magnitude, and equal intervals + true zero point
score data

Front 13

scale attenuation effects

Back 13

restricting range of scale
ceiling effect=no room to show change toward higher scores
floor effect= restricted lower range

Front 14

chi square

Back 14

assess relationship b/w 2 nomial variables

Front 15

common causal variables

Back 15

cause both predictor and outcome, thus produce correlation b/w them

spurious relationship=produces and 'explains away' relationship b/w predictor and outcome variables

Front 16

longitutdal research

Back 16

path anaylsis= multiple regression to assess the relationships among number of measured variables
