Me, Myself and I (7) Flashcards
we can use a regression analysis to determine what
the variation between two variables and the R2 value
what does the adjusted R2 value give
a percentage of the data whom the null hypothesis applies to
when would the fishers exact test be more applicable than a chi-squared
when we have a sample size smaller than 5
when would we use a multivariate linear model
if we are testing for independence between two or more factors
what is cherry-picking within data analysis
only presenting the data results that are positive and ignoring the other results
why is cherry-picking within data analysis discouraged
it creates a misrepresentation of the data whereas it should be open and transparent
what are the negatives about multiple testing
testing all the results until you find a positive one and using it regardless of if its the best aproach
what does multiple testing allow us to identify
some real biological modifiers, some co-variables and some chance associations
what does cross-sectional data represent
a snapshot of different individuals at a certain time
what does longitudinal data represent
to investigate how the data changes over time
