Central question: How many X does the phrase some X next to a Y refer to? Your predictors are

  • OBJECT: the sizes of the objects X: large vs. small;
  • REFPOINT: the sizes of the reference points Y: large vs. small.

Analyze the data properly with a regression model and summarize the results (briefly).

rm(list=ls(all.names=TRUE))
summary(x <- read.delim(   # summarize x, the result of loading
   file="105_11_some.csv", # this file
   stringsAsFactors=TRUE)) # change categorical variables into factors
##       CASE         OBJECT   REFPOINT    ESTIMATE   
##  Min.   : 1.00   large:8   large:8   Min.   : 2.0  
##  1st Qu.: 4.75   small:8   small:8   1st Qu.:38.5  
##  Median : 8.50                       Median :44.0  
##  Mean   : 8.50                       Mean   :51.5  
##  3rd Qu.:12.25                       3rd Qu.:73.0  
##  Max.   :16.00                       Max.   :91.0
