Bias
Jean Piaget is pretty much king of the
child psychologist world, his cognitive development theory, which has informed
much of my research project to date, is respected and informs curriculums and
parenting methods still to this day. A lot of his research and observational
study was carried out with his own three children, yet his theory and
discoveries are still relevant, respected and accurate. Piaget believed samples
were valid as long as the structures that were identified were present/common
amongst all individuals. Essentially if the research of the 1% I have chosen
can be proved to reflect the 99% not chosen, the research can be trusted and
the assumptions drawn reasonable.
Sampling bias is a non-probability sampling
technique, the subjects being chosen for their proximity and accessibility. It
is often used due to its low cost, speed and ease and can lead to systematic
bias, whereby the results of the non-random sample do not reflect that of the
entire population neglected by the study. In order minimize bias within my
results I plan to carry out continuous secondary research and reading, to
constantly test the data I receive, and gain a better understanding of the
credibility of my research. I will also be carrying out quick surveys and
questionnaires to further support or disprove my results. So I should avoid
freak anomalies due to my chosen sample, who ent’ freaks anyway. There you’re
general mini family, data I get from them should be as good as anywhere else,
as long as I conduct the thing right.
“
Science is about recognizing patterns”
That’s
what Christopher Knight said, and I’m with him.
This being said, it is an undisputable fact
that you can’t ever eliminate bias from a research study, it’s an inescapable
element of research, and the human nature. In fact Droyspencer from Climategate said
“Seeking to reduct bias through
controlled experiments takes away the data from real-world complexity in which
scientific results must be applied to solve problems” …So it could be said
bias might sometimes not be an entirely negative thing. The only steps that can
be taken are to identify, limit and minimize the impact of bias, which ‘m going
to do through the following measures:
I’m gonna get someone else to carry out my
artefact !
“And
why beholdest though the mote that is in thy brothers eye but considerest not
the beam that is in thine own eye”
Matthew
7:3 (King James Verision)
Bible speak is an effort to type, but
Identifying bias in others is easy peasy, but in yourself, not so much. We’re
all pretty blind to our own susceptibility, tiny things like body language and
facial expressions, uncontrollable intricacies could influence the decisions
and approach of my younger brother, he could be egged on to do some more if he
see’s me grinning at him, or want to leave it be if he see’s I look bored as a
need to please, Bowlby taught me that shit. So I’m gonna get me pal to do it
for me which should level out and rival the possible implications of measurement
bias.
The guy I’m gonna get to do it will be
prepared with the same sort of paperwork that I’m gonna give to my Mom, and
instructions of what needs to be done in terms of physical actions…that’s
pretty much all he get’s to know. You know me, not big for talking, so both the
respondent, the other respondent and my interviewer have little to no
information about the motivations behind my project, the sort of results I’d
love to receive, or any other kinda of details that could influence their
actions and natural responses. Essentially, I’m trying to carry out a Double
Blind experiment, where neither party can give away or affect the results, they
both only know moderated information, the bare minimum, so there should be
little to no chance of them playing up to what they think I might want or not
want, or acting to their understanding of the project; a control measure to the
sampling choice. Nice and Fair.
A book I read called Growing Up With
Technology by Plowman, Stephen and McPake, explains considerations when
conducting research with children. They detail the importance of building a
rapport and the trusted relationship between the respondent and interviewer, it
is for this reason the guy who’s carrying out my artefact isn’t someone I found
off the street, but someone who’s met both my Mom and younger brother Isaac a
couple of times; Enough for them to be comfortable in each other’s company
without me there, but not comfortable enough to be passing wind or talking
aloud.
(Despite my slightly jokey style o writing,
I am serious in my approach, I’m taking the whole thing really serious, cos
it’s something I’m passionate about)
I’ve researched into the importance of the
interview setting, and have decided due to the control measure of the external
interviewer the best setting for Isaac and my Mom to be in, to ensure their
comfortable and natural, is their home. I don’t want the results to be skewed
by their unease or unnatural emotional response.
Conclusion
I’m gonna blog how my sample choice differs
from the ideal sample, the attributes and qualities absent. I’m going to have a
look at how the results I get correlate to existing research and theories
through continued reading. I’m going to conduct anonymous surveys and
questionnaires, essentially evaluating my data, getting as much information
from as varied approaches as I can acquire. I’m gonna get someone else to
conduct my interview for me, and I’ve already taken a look and figured out what
my data will mean, how it can be measured and what I can do with it.
