CRM Week 2 Flashcards
what does a hypothesis mean
a scientific question
what does this hypothesis have to be
testable and falsifiable/refutable
what are some tips for creating a good hypothesis
clear and well stated, single hypothesis rather than multiple,
what are examples of reference management software
ProQuest (RefWorks), Mendeley, Zotaro
Research is spending …
6 hours reading 35 papers, so you can write one sentence containing 2 references.
Tips for Critical Evaluation
You do not read papers to find a direct answer, identify the hypothesis (goal, aim or purpose), intentional judgement to select quality evidence related to your research, be willing to tolerate uncertainty.
what is a statistical hypothesis
a pair of refined questions that can be tested by an appropriate statistical model
what should the statical hypothesis be
exclusive and exhaustive
what two hypothesis do you need
a research hypothesis and a null hypothesis
what is a quantitative variable
something you can assign numbers to
what is an example of qualitative variable
sex, hair or eye colour
what is a response variable
measures of an outcome of a research/study (e.g. VA, change in level of alcohol in blood after drinking)
what is an explanatory (independent) variable
explains or influences changes in a response variable (e.g. how much a person drinks per day)
what is a null hypothesis (H0)
statement about the values of unknown (response) variable when no effect is assumed - the hypothesis you want to refute in favour of H1
what is an alternative hypothesis (H1)
an opposite statement against null hypothesis - typically your research hypothesis that you support
what are things to consider when designing research
subject/sample size , measurement, ethics and design
what are the types of clinical research
qualitative or quantitative, descriptive or analytic, observational or experimental
what is qualitative research
usually explorative and descriptive, collected in the form of words or media
what is quantitative research
data collected in the form of numbers that are subject to further numerical analysis
what is descriptive research
mainly interested in measuring and summarising the pattern or frequency of variables of interest
what is analytic research
interested in the dynamics between the variables based on the descriptive data collected on the variables
what is observational research
to investigate the pattern or the relationship between two or more variables without being directly interfered or manipulated under natural conditions
what is experimental research
one or more variables are manipulated to see its effect on other variables under highly controlled environment - almost always analytical
tertium quid (confounding variable)
third variable
