Lecture 3- ways of collecting information qualitatively
Interviews
Semi-Structured Interviews
Open to exploration and deviation
inbetween structured and Unstructured
NOT
Tightly scripted but have few questions that covers some topics.
balance of breadth and depth but time constraints may make neither reachable
Need more expertise than structured interview
pseudo-replicable and unstructured
medium difficult to analyse
Structured Interviews
tightly scripted
Fast
Simple to analyse
No opportunity to respond to something interesting as it is tightly scripted
Easy to replicate
similar to Questionairres
difficult to change question or interview script and structure before or after interview
Surface deep data
Ordinal/ interval data
good for creating empathy with users :crown:
ALL INTERVIEWS REQUIRE A PLAN OF SOME SORT
Unstructured
only initial question and then go with flow
deep data
Interviewers will still do prep and research... no definite plan
replication difficult
hard to balance breadth and depth in Unstructured interview
data is unstructured therefore analysis is hard
opportunity to follow up on anything interesting
what type of interview?
depends on
amount of time
knowledge of industry
When
interviewer expertise
what type of data needed
purpose
Questionnaires
open ended questions allowed
but complex analysis + longer
quality questions will yield quality results
easy to capture data from large number of people
can't capture data about things you don't know about
use at any stage
paper version of structured interview
type of data
Rankings
Likert Scales
Checkbox questions
Semantic differentials
Scope of Questionnaires
Concepts- what best describes Z
Expectations/ metal models- What would you expect to happen if A
Behaviours- how often do you Y
Expertise- what is A+B
User attitudes - do you like X
Contextual Inquiry
is a methodology based on observing people in their natural selves and if possible natural environment
because people find it hard to verbalise their skills (on how to do a thing)
can also observe people in a lab
trimmed down (3months to 3 hours)
extensive data exploration becomes lightweight business reporting and requirement capture
Rooted in Ethnography
Ethnography principles
record behaviour and analyse later
process of unguided observation to gain deeper understanding of...
culture
context
process
observe natural settings
Interview key people based on understanding
Capture tiny details of the broader picture
formal methods inc.
watching and coding of captured data
conversation analytics
agreement scores
EXP Sampling
Similar to Questionairre...
BUT
ask same question over and over again
ask in intervals / a certain frequency
every 2 hrs
every 90 seconds
every time they do a certain action
remember to keep it short when asking frequently
empathy
GOOD FOR LIVE DATA
:woman-swimming::skin-tone-2:
Diary Studies
slightly longer and less frequent less guided
than EXP sampling
Frequencies
once a day
once a week
participants respond in an open manner to a prompt about....
behaviour, opinions, frustrations
participants get a diary at the end of the process
SO WHAT METHOD IS GOOD
depends on
what are you trying to solve/ find out
size of population
users
