Resampling One

Question 1

what is a resampling approach

Answer 1

a newer method of statistical analysis

measures sampling error by repeating the sampling process a large number of times - assessing the variability in the resamples

Question 2

why would we use a resampling approach

Answer 2

fewer assumptions

more accurate in cases that dont fit the assumptions of typical statistics

very general - ideas can be modified to different situations

no equatins or tables

we have to think about our data

Question 3

why arent resampling approaches more popular

Answer 3

theyre new - about 30 years old

parametric stats are how people have been trained and theres lots of rescources on it

requires some programming

cant be done in SPSS

Question 4

how do we do a between subject resample

Answer 4

• data is randomly reassigned between two groups and the difference between the resampled means is recorded on a graph

then we check how extreme the real value is on this graph

work out how many means were more extremee than this and convert this percentage to a decimal - 1/10 more extreme, so 10% so p=0.1 so not statisically significant
