epidomology Flashcards
List the quantitative and qualitative data, discrete and continuous data
What is data
There are 2 types of data qualitative and quantitative data
Facts collected and puttted together in for analysis in order to conclude the process
Deference’s between these 2 data
Qualitative - non statistical and typically
semi structured
Does not use big numbers and graphs
Basically uses labels, attributes and other indentifications
Eg sex gender mood of flavour of chocolate filling
Quantitative data- is measured using numbers and values there is an appropriate data for analysis.
Discrete vs continuous data
Discrete-
Connor be broken down into smaller parts and consist of intergers
Continuous- data that can be broken down into smaller parts
What is study
Study is a scientific process of gathering information and answering questions using data from population.
You have a hypothesis to prove
And steps on the study.
Types of epidemiology studies
Observational- discriptive study
Analytic study
Experimental - random control trial
Observational study
Descriptive- case reports, case series
Ecological and cross sectional
Analytical- case control and cohort
Observational
Just watch and look at universe unfolding
Experimental
Researchers start to intervene and change variables
Epidemiology activities
Descriptive- looks at person time and place : what when
Drywall with one variables
analytic studies- looks at determinants possibilities of causes and outcomes: why?
Deals with association
Descriptive
Aim to calculate amount and distribution
Analytic
Aim to calculate possible cause of
Errors of epidemiology
Random and systematic- bias
Random error
May occur in. Data collection and possible decrease error by increasing sample
Bias error
Occurs when data differ from the true value in a systematic manner
Outcome and exposure are not correct
