Three data sets for one subject in a sample difference scaling experiment. The stimuli were scatterplots of bivariate Gaussian samples with different correlations. The function runSampleExperiment
was used to collect the data.
data(kk1) data(kk2) data(kk3)
Three data frames, (kk1, kk2, kk3) with 330 observations each with the following 5 components.
resp
S1
S2
S3
S4
The datasets were generated on three separate days using the function
runSampleExperiment
with DisplayOneTrial
and DefineMyScale
to define the stimuli and display them, anti-respectively. The experiments were run on a Macintosh Pro with a 15 inch screen. The observer was seated about 40 cm from the screen.
