Dialogue: 0,0:00:10.60,0:00:13.97,Default,,0000,0000,0000,,I received several requests to tell you a bit more \Nabout the difference
Dialogue: 0,0:00:13.97,0:00:17.63,Default,,0000,0000,0000,,between primary and secondary research \Nmethods
Dialogue: 0,0:00:17.63,0:00:22.67,Default,,0000,0000,0000,,and explain a bit when we use the first and when \Nthe second.
Dialogue: 0,0:00:22.67,0:00:26.90,Default,,0000,0000,0000,,The most basic distinction between primary and \Nsecondary research is this..
Dialogue: 0,0:00:26.90,0:00:31.47,Default,,0000,0000,0000,,Primary research is when we use original data.
Dialogue: 0,0:00:31.47,0:00:40.33,Default,,0000,0000,0000,,It is simply put, new data. Secondary research \Nis when we study the results of others.
Dialogue: 0,0:00:40.33,0:00:43.80,Default,,0000,0000,0000,,Because these results are often published in \Nscientific journals and books,
Dialogue: 0,0:00:43.80,0:00:48.93,Default,,0000,0000,0000,,we also refer to this as a literature study.
Dialogue: 0,0:00:48.93,0:00:52.30,Default,,0000,0000,0000,,And because you often sit behind a desk \Nreading these articles,
Dialogue: 0,0:00:52.30,0:00:55.73,Default,,0000,0000,0000,,it’s also named desk research.
Dialogue: 0,0:00:55.73,0:01:02.17,Default,,0000,0000,0000,,Secondary research is basically the systematic \Nreview of existing knowledge.
Dialogue: 0,0:01:02.17,0:01:07.03,Default,,0000,0000,0000,,So when do scholars perform primary or \Nsecondary research?
Dialogue: 0,0:01:07.03,0:01:13.13,Default,,0000,0000,0000,,Well, often we do both in different stages of a \Nlarger study.
Dialogue: 0,0:01:13.13,0:01:18.10,Default,,0000,0000,0000,,Let’s say I’m interested in the effects of fear \Nappeals in anti-smoking campaigns.
Dialogue: 0,0:01:18.10,0:01:22.93,Default,,0000,0000,0000,,More specifically: I want to know if a Dutch anti-\Nsmoking campaign
Dialogue: 0,0:01:22.93,0:01:27.73,Default,,0000,0000,0000,,should make more use of them in order to \Nbecome more effective.
Dialogue: 0,0:01:27.73,0:01:32.10,Default,,0000,0000,0000,,I will start by exploring the existing literature on \Nthe use of fear appeals,
Dialogue: 0,0:01:32.10,0:01:37.17,Default,,0000,0000,0000,,anti-smoking campaigns, health campaigns in \Ngeneral,
Dialogue: 0,0:01:37.17,0:01:43.07,Default,,0000,0000,0000,,studies in to why people smoke, when people \Nblock fear appeals, et cetera.
Dialogue: 0,0:01:43.07,0:01:50.73,Default,,0000,0000,0000,,I systematically collect all of this secondary \Ndata, basically the research findings of others,
Dialogue: 0,0:01:50.73,0:01:54.53,Default,,0000,0000,0000,,and analyze these results in order to come up \Nwith some expectations
Dialogue: 0,0:01:54.53,0:02:00.83,Default,,0000,0000,0000,,of what would happen if we would use more fear \Nappeals in Dutch anti-smoking campaigns.
Dialogue: 0,0:02:00.83,0:02:06.67,Default,,0000,0000,0000,,In some cases, if time, money or practicality \Nforces us to limit ourselves to a literature study,
Dialogue: 0,0:02:06.67,0:02:10.57,Default,,0000,0000,0000,,this is where my research ends.
Dialogue: 0,0:02:10.57,0:02:15.97,Default,,0000,0000,0000,,But often, if I want to really understand \Nsomething and delve deeper in to the question,
Dialogue: 0,0:02:15.97,0:02:21.03,Default,,0000,0000,0000,,I want to study this further and in more detail.
Dialogue: 0,0:02:21.03,0:02:25.20,Default,,0000,0000,0000,,Existing studies might have been conducted in \Nother countries for instance,
Dialogue: 0,0:02:25.20,0:02:30.97,Default,,0000,0000,0000,,so I’m wondering if these results will also be true \Nin the NL.
Dialogue: 0,0:02:30.97,0:02:36.83,Default,,0000,0000,0000,,Or, it’s also possible no study has looked \Nspecifically at this target group
Dialogue: 0,0:02:36.83,0:02:41.90,Default,,0000,0000,0000,,or what happens over a prolonged period in time.
Dialogue: 0,0:02:41.90,0:02:46.63,Default,,0000,0000,0000,,In short: A review of the existing literature can \Nleave us with a thousand questions
Dialogue: 0,0:02:46.63,0:02:51.23,Default,,0000,0000,0000,,and things we want to check or explore in more \Ndetail.
Dialogue: 0,0:02:51.23,0:02:54.97,Default,,0000,0000,0000,,So now I need to conduct my own, primary, \Nresearch.
Dialogue: 0,0:02:54.97,0:02:59.80,Default,,0000,0000,0000,,My desk research has left me with several \Nresearch hypotheses
Dialogue: 0,0:02:59.80,0:03:04.70,Default,,0000,0000,0000,,that we will set out to prove or disprove with \Noriginal data.
Dialogue: 0,0:03:04.70,0:03:09.63,Default,,0000,0000,0000,,If the research findings you find in the literature \Nare reliable
Dialogue: 0,0:03:09.63,0:03:15.50,Default,,0000,0000,0000,,I should be able to replicate them. This is why \Nreplication of existing studies,
Dialogue: 0,0:03:15.50,0:03:18.50,Default,,0000,0000,0000,,sometimes with only one small variation,
Dialogue: 0,0:03:18.50,0:03:25.37,Default,,0000,0000,0000,,is an important scientific tool. In order to be sure \Nof what we know, we keep checking it
Dialogue: 0,0:03:25.37,0:03:30.93,Default,,0000,0000,0000,,and keep changing the research context slightly \Nto see if that makes a difference.
Dialogue: 0,0:03:30.93,0:03:35.63,Default,,0000,0000,0000,,Of course next to checking the reliability of \Nexisting data,
Dialogue: 0,0:03:35.63,0:03:40.100,Default,,0000,0000,0000,,primary research also allows us to radically \Nexpand on existing knowledge
Dialogue: 0,0:03:41.00,0:03:43.77,Default,,0000,0000,0000,,by adding completely new research variables,
Dialogue: 0,0:03:43.77,0:03:49.57,Default,,0000,0000,0000,,leading to new insights into previously \Nunexplored relationships.
Dialogue: 0,0:03:49.57,0:03:54.47,Default,,0000,0000,0000,,So in a nutshell: we usually start with secondary \Nresearch.
Dialogue: 0,0:03:54.47,0:03:58.50,Default,,0000,0000,0000,,That’s why, whenever we discuss research \Nmethods,
Dialogue: 0,0:03:58.50,0:04:02.20,Default,,0000,0000,0000,,we should not forget this important category.
Dialogue: 0,0:04:02.20,0:04:07.63,Default,,0000,0000,0000,,Many questions have already been asked and \Nanswered by scholars all over the world
Dialogue: 0,0:04:07.63,0:04:11.40,Default,,0000,0000,0000,,and a systematic review of existing data will \Nallow us
Dialogue: 0,0:04:11.40,0:04:17.17,Default,,0000,0000,0000,,to formulate hypotheses and more specific \Nresearch questions.
Dialogue: 0,0:04:17.17,0:04:20.97,Default,,0000,0000,0000,,The introduction of digital search engines has \Ngreatly increased our ability
Dialogue: 0,0:04:20.97,0:04:27.77,Default,,0000,0000,0000,,to find and use existing studies, our ability ‘to \Nstand on the shoulders of giants’ as it were.
Dialogue: 0,0:04:27.77,0:04:34.93,Default,,0000,0000,0000,,Famous words by Newton, now the motto of \NGoogle Scholar.
Dialogue: 0,0:04:34.93,0:04:39.60,Default,,0000,0000,0000,,After we have studied existing knowledge we \Ntest our expectations
Dialogue: 0,0:04:39.60,0:04:46.20,Default,,0000,0000,0000,,and further expand on this by conducting our \Nown primary research,
Dialogue: 0,0:04:46.20,0:04:48.87,Default,,0000,0000,0000,,if we have the time and money that is.
