Measurment

Question 1

realibility

Answer 1

is your measure consistent ?

Question 2

every construct has a true score

Answer 2

-Intelligence
-Height
-Weight
-Running speed
-Happiness
-Boredom
-Etc…

Question 3

your ‘‘real level’’

Answer 3

can be mesured
hight
weight
iq

Question 4

for any constract,each participant has a true score

Answer 4

must reley on mesurment to find true scores, which has measurment error

a measure is realible if it has little measurement error

Question 5

how to avoid mesurment error

Answer 5

-measure repetly

Question 6

realibilly is your first concern

Answer 6

if it isnt measuring a thing constitly- no realibily ,= no validity

Question 7

realibily

Answer 7

if the finding is consistent trought trials

Question 8

validity

Answer 8

if it measures what we want to measure/but acuratly

Question 9

types of realibity

Answer 9

1-test-retest realibily
2-internal consistent realibility
3-inter

Question 10

we use correlation to meausre realibility

Question 11

1. test-retest realibily

Answer 11

is a participant score consistent across time(tests)- r=0.8

Question 12

2.internal consistent realibility

Answer 12

is participants score on this construct similar across iteams that are aimed to measure related aspect of construct

Question 13

table

Answer 13

?

Question 14

3.inter-rater realibilty

Answer 14

how similar are a participants score when measured by different reters

relevant when behaviour is observed or text are coded by multiple rater

Question 15

validity

Answer 15

are u measing what u want to measure?

Question 16

construct validity

Answer 16

1. does contant reflect the iteam u want to measure
   a)face validity
   b)content validity
2. how does this measure behaviour?
   c)Predictive
   d)Concurrent
3. how does this measure relate to other measures ?
   e) Convergent
   f) Discriminant

Question 17

a) face validity

Answer 17

is it measuring what u want to measure?

Question 18

b) content validity

Answer 18

is it capturing all important parts of the iteam/concept being measured ?- is something missing

Question 19

c)predictive

Answer 19

it will predict accuratly future behaviour

Question 20

d)concurrent validity

Answer 20

able to distinguish relevent behaviour now
that has to do with concept being measured
ex:lonlines are they going to parties

Question 21

e) convergengengt validity

Answer 21

related to scores on measures of similar constructs

Question 22

f)discriminant

Answer 22

not related to what shouldt relate to
(low or zero correlation)
ex:don’t want to be measuring depression ! we want to measure loneliness!
