Variables
Procedure for assigning numerical values to represent
Measurement
Determine the “level of statistical analysis that can be used” and the type of conclusion that can be drawn
Level of measurement
Used to classify into categories but CANNOT BE RANKED
Nominal
Identify the level of measurement:
Gender
Nominal
Identify the level of measurement:
Civil status (single, married)
Nominal
Shows the RELATIVE RANKINGS if variables and in ordering observations
Ordinal
Ordinal are ranked from:
Highest to lowest; Most to least
The ‘DEVICES designed to ASSIGN A NUMERIC SCORE’ for people to place them in continuum
Scale
Identify the level of measurement:
Scale
Ordinal
Consists of several declarative items that ‘EXPRESS A VIEWPOINT OF THE TOPIC ‘
Likert scale
Participants are asked to “rate concepts on a series of bipolar adjectives”
Semantic Differential Scale
Identify the level of measurement:
Respondents place a check at the appropriate point on a 7 point scale
Semantic differential scale
‘BRIEF CASE REPORT’ or description of events to which ‘respondents are ASKED TO REACT’
Vignette
Participants are presented with a SET OF CARDS on which words or phrases are written
Q-sorts
Used to measure subjective experiences
Visual Analogue Scale
Identify the level of measurement:
Pain, fatigue, dyspnea
Visual Analogue Scale
A scale in which respondents are asked to rate something on bipolar dimension
Graphic Rating Scale
Ranking of variables on a scale with equal INTERVALS between the numbers, consists of real numbers. The ZERO POINT remains ARBITRARY and NOT ABSOLUTE
Interval
Ranking of variables on scale with equal intervals, distance between ranks is specified up to the zero point level, ZERO IS ABSOLUTE
Ratio
Identify the level of measurement:
Temperature
Interval
Identify the level of measurement:
Date, pH
Interval
Identify the level of measurement:
Weight, height
Ratio
Identify the level of measurement:
temp in kelvin
Ratio
Identify the level of measurement: number of children
ratio
Identify the level of measurement: income
