This document discusses common errors in research and their implications. It begins by outlining the differences between quantitative and qualitative research approaches. Common errors for various research methods like questionnaires, interviews, experiments and observational studies are then described. These errors can lead to wrong business decisions, loss of capital, and market failures if research conclusions are flawed. Finally, steps like conducting a literature review, using statistical tools, double entry of data, pilot testing, and training of researchers are suggested to minimize errors.

3. Qualitative and Quantitative research
Quantitative Qualitative
Deductive Inductive
Tests hypotheses Produces theories
Positivism Phenomenology
Objectivism Constructionism
Employs measurement Does not employ measurement
Measures objective facts Constructs social meaning
Focuses on variables Focus on interactive processes
Reliability is key Authenticity is key
Independent of context Context constrained
Statistical analysis Thematic analysis
5. Qualitative Errors
Selective observation
Inaccurate observation
Overgeneralization
Made-up information
Ex post facto hypothesizing
Illogical reasoning
Ego involvement in understanding
Premature closure of inquiry
Mystification
6. Common Errors In Research
Questionnaire Studies
Using a questionnaire to work with problems that lend
themselves better to other research techniques.
Not giving enough care to the development of the questionnaire
and not pretesting it.
Asking too many questions, thus making unreasonable
demands on the respondents time.
Overlooking details of format, grammar, printing, and so on that
can influence respondents. first impression.
Interview Studies
Not adequately planning the interview or developing the
interview guide.
Not conducting sufficient practice interviews to acquire needed
skills.
Failing to establish safeguards against interviewer bias.
7. Experimental Studies
Inadvertently or otherwise treating the experimental and control groups
differently, thus leading to biased findings.
Using too few cases, leading to large sampling errors and insignificant
results.
Failing to divide the main groups into subgroups in situations where
subgroup analysis may produce worthwhile knowledge.
Observational Studies
Not sufficiently training observers and thus obtaining unreliable data.
Using an observation procedure that demands too much of the observer.
Failing to safeguard against the observer’s disturbing or changing the
situation being observed
Relationship (Correlation) Studies
Assuming that a correlation between pieces of data is proof of a cause-and
effect relationship.
Using a sample in correlational research that differs on so many variables
that comparisons of groups are not interpretable.
Selecting variables for correlation that have been found unproductive in
previous studies.
