Strengths & Limitations of Quantitative Methods
p 60-66
Questionnaires
Limitations
low response rate
difficult to examine complex issues and opinions
lack of potentially significant data
unintentionally biased/ ambiguous questions
low validity
no way of knowing whether a respondent understood question properly
Strengths
highly reliable data
higher validity
easy replication
Structured Interviews
Limitations
reduced validity
dishonest answers & interview effect
lack of anonymity
Strengths
:
clarification of question meaning
100% response rate
Content Analysis
Strengths
can identify recurrent themes
predictive qualities: can be used to draw complex conclusions from simple data-collection techniques
Limitations
question of organization of behavior
difficult to replicate
limited reliability
Laboratory Experiments
Limitations
Hawthorne effect
compromised validity since taking place in an artificial environment
Strengths
easier to replicate
standardisation allows for reliability
Field/natural experiments
Limitations
low reliability
more difficult to replicate
Strengths
results in more realistic data
can be used to manipulate situations in the real world to understand the underlying reasons for daily behavior
Longitudinal Surveys
Limitations
high levels of sample attrition
results of data are only a glimpse of daily life/behavior at any given moment (despite over time)
lack depth and validity
Strengths
can be used to summarize vast sources of information
easier to make comparisions across categories and over time
generate reliable representative samples to suggest casual relationships
Cross-Sectional surveys
Limitations
can't be used to measure behavior over time
Strengths
analyzes multiple variables at any given time
possible to explain differences in events/behavior using variations in standardised variables (ex.
easier to establish correlations
Official Statistics
Limitations
only give partial picture of reality
does not discuss unrecorded crimes
does not reveal the reasons for behavior
Strengths
high representation
reliable
usually definitive and accurate
