1
Q

4 sources of research ideas?

A

practical problems
past research/literacy search
observations
common sense

2
Q

define basic research

A

research aimed to gather knowledge or address theoretical questions

3
Q

define applied research

A

research aimed to solve practical problems

4
Q

3 properties of a good theory

A
  • PARSIMONY (theory adopts the simplest explanation)
  • predictions are PRECISE
  • theory withstands RIGOROUS TESTING
5
Q

4 properties of a good hypothesis?

A

testable
positive
logical
refutable

6
Q

do you know IV, DV, EV, CV etcyes

A

yes

7
Q

define: quasi-independent/subject variabls

A

variables that are pre-existing and unable to be manipulated by the researcher - eg. age, sex

8
Q

nominal, ordinal, interval, ratio scales of measurement

A

nominal: names variable
ordinal: names and ranks variable
interval: names and ranks variable, with equal distances between intervals (personality test scores, temperature)
ratio: names and ranks variables, equal distance between intervals, absolute zero (weight, height)

9
Q

define: content validity

A

when a measure’s items cover a representative range of behaviours being measured

10
Q

define: face validity

A

when a measure appears to measure what is claiming to

11
Q

define: concurrent validity

A

when a new measure is consistent with more established measures of the same variable

12
Q

define: predictive validity

A

when the measure predicts what its meant to

13
Q

define: construct validity

A

when measurements behave the same way as the variable itself

14
Q

define: split halves reliability

A

if the measure is split in half, the results are consistent between two halves

15
Q

define: parallel/equivalent forms reliability

A

consistency between two forms of a test that are designed to be equivalent
