00:01
Hi, I'm Doctor Rhonda Lawes, and I'm here to
have the discussion you didn't really ask for.
00:06
You didn't even know how much you
needed.
00:07
But I promise you it's going to be worth
your time.
00:10
This is an introduction to research
methodology.
00:13
It's way more fun than it sounds.
00:16
See, research methodologies, kind of the
rules.
00:18
It's the guidelines or the guardrails.
00:20
It's a very systematic process that guides
the researcher in how to conduct the study.
00:25
Now, it involves various techniques,
procedures, and tools to collect, analyze,
and interpret the data.
00:31
Stay with me. I promise this is going to be
helpful to you.
00:34
Now understanding research methodology is really
important for students because this is what's
going to form the foundation for you
understanding meaningful and valid
research. So, overall research methodology
is essential for you
understanding that the research process is
rigorous, it's transparent, and it has to be
capable of producing reliable and valid
results.
00:57
So research methodology matters.
00:59
Now, the specific approach taken will depend
on the nature of the research.
01:03
The research questions, the disciplinary
traditions, blah blah blah blah blah.
01:07
All this stuff on and on.
01:08
Let's get into some basics.
01:10
Now I've broken it down into chunks so it's
easier for you to understand and remember.
01:15
Okay, so walk with me through
these five important concepts in the
value and purpose of a research methodology.
01:23
Now, first of all, research methodology
helps identify the research
problems. It kind of clearly defines it and
gives an understanding of the research
problem that this study aims to address.
01:35
Now, that's a pretty basic thing.
01:36
Everyone needs to be on the same page, pun
intended, of what the research
problem is that we're exploring.
01:43
Secondly, data collection.
01:45
Now, data collection is this research
methodology provides a
framework for collecting relevant data
through various methods like surveys,
interviews, experiments, and observations.
01:57
So when the study is being designed, how the
data will be collected
is the second important component of
research methodology.
02:05
Third, Data analysis.
02:08
Now we've identified the research problem.
02:10
We've explained how we're going to collect
the data.
02:12
Now how we analyze the data is the third key
important concept in
research methodology.
02:19
See it assists in choosing appropriate
statistical or analytical tools for
interpreting the collected data.
02:25
Now, this may sound simple to you, but I
remember in my dissertation my committee had
multiple arguments and fights over which
type of data analysis should
be done. So this is often a point of
contention between the
experts on which would be the best or the
most effective form of data analysis.
02:45
Number four: ensuring validity and
reliability.
02:49
Now keep in mind research methodology has to
address both of these things
validity and reliability because it helps in
the designing the
research plan that ensures your study and
your results will be valid and
reliable. That makes your results more
credible.
03:06
Number five is generalization.
03:09
Man, this is a huge one.
03:11
Research methodology allows researchers to
generalize findings from a
sample to a larger population.
03:19
Now, when you have good and strong
generalizability, this makes your
study worth more to society, because you can
have external validity
of the study and your results outside of
your small sample group.
03:33
Now let's talk about how we organize
research designs into groups.
03:38
So anytime you get a list of something let's
go through it and just see what the framework is.
03:42
We have qualitative research,
quantitative research, mixed
methods research, experimental research, and
case
study research. Now those may not mean much
to you right now, but we're going
to kind of go through and give you examples
so you have a better understanding of what
they are now. When I first started studying
research as an undergrad, I always got
confused on the difference between
qualitative and quantitative.
04:09
Both are important.
04:11
Now, you may not you might not feel like
that when you hear educators arguing about
which has more value and who likes quant and
who likes qual.
04:19
But I want you more to understand the
difference.
04:22
Qualitative research is critically important
because it helps us understand what people
think about something, what their experience
is like, what the problems they might list.
04:31
So qualitative is not absolutely measuring
something.
04:35
It involves interviewing people.
04:36
You may work with focus groups, and you
analyze the content of things.
04:41
You're looking for ways to gather
information in a nontraditional manner.
04:45
So you're trying to understand and interpret
the underlying things that are
going on with humans or with people.
04:53
Now, quantitative research might appear more
scientific, but it's really not.
04:58
But it's communicated more with numbers and
analyzing
numerical data.
05:04
Now, if you think qualitative research
doesn't require analyzing oh no, no, no.
05:08
Because when you do the interviews you write
out people's responses.
05:12
And then it takes many, many, many, many
hours of going through those responses and
grouping them together and categorizing them
and looking for patterns and interpreting that.
05:21
So both require interpretation.
05:24
But qualitative research has to
predominantly be done by a human with some
computer assistance, quantitative research
that the analysis is usually
done with really fancy math programs to give
you statistical
analysis. Both are valid.
05:41
Qualitative research can also inform what
you would want to study quantitatively.
05:45
But an example of quantitative research
could be, hey, let's look at the impact of
blood pressure with this medication.
05:51
Which one better controlled hypertension.
05:54
Well then we would have some numbers to play
with right.
05:56
And we could see the differences in blood
pressure measurements.
05:59
That's not how do you feel about your blood
pressure or what have you experienced with
your blood pressure. What have been the most
difficulties in your perception?
So you want to know that qualitative is
going to be more of the qualities about the
research problem and what you're talking
about.
06:14
Quantitative research is going to give you
more quantitative numbers, but
both are critically important.
06:23
Now mixed method research.
06:24
If that wasn't enough for you.
06:27
This has both qualitative and quantitative
approaches in one
study, and that's really cool if you can see
those together, because you can really see
how they play off each other, how they
interact, and get a better understanding of
the research problem you're looking at now.
06:42
Number four is experimental research.
06:45
Now, this means you have to manipulate
variables because you want to manipulate the
variables and kind of see what the effects
and cause and effect relationships are.
06:52
So that's pretty fancy stuff.
06:55
But it's also very clear cut case study
research again,
that's an in-depth exploration of specific
cases or phenomenons because you want
to learn more about that.
07:06
So you may look at like what it feels like
to be a first semester medical student or a
beginning nursing student, or a PA just
starting their practice.
07:14
That would be a case study, because we're
looking at a specific case or phenomenon to
learn more about it.
07:21
Now, the key components of research
methodology we've got research design.
07:25
We talked about that.
07:26
You have sampling techniques, data
collection methods data analysis,
and ethical considerations.
07:33
So when I'm thinking about research
methodology what does that all enclose.
07:38
Well it's research design right.
07:41
That's the overall plan the structure of
your research.
07:43
What type of study, how you're going to
collect your data and how you're going to
analyze it.
07:47
Sampling techniques that will say, how did
you pick a representative group of
people of the population that you studied
and used in your study?
Because remember, the more representative of
the general population your study is,
the better chance you have of being able
to generalize those findings to the whole world.
08:06
Well, not always the whole world, but
a larger group of people.
08:10
Three data collection methods.
08:12
Now, research methodology is going to help
determine what's the most appropriate
data collection method.
08:18
You can use data collection methods like
surveys, interviews, observations, and
experiments. Data analysis are those unique
and special
tools that you use to analyze the collected
data.
08:31
Now it might be statistical tests,
qualitative coding that I talked about or
thematic analysis.
08:37
And that is just as complex as it sounds,
that thematic analysis is what
goes with the qualitative data.
08:44
Now fifth, ethical considerations is part of
everything.
08:48
And of course it's part of the key
components of research methodology.
08:52
These are the guidelines and the principles
to make sure the ethical conduct of the
research, including participant consent,
confidentiality, and honesty.
09:02
So in wrapping this up, the
language of research methodology is
complex and new, but focusing on the purpose
of each type can help you.
09:10
Knowing the purpose and the method can help
you organize your search and use of research knowledge.
