These are the raw data of the paper entitled "Benchmark-based strategy use in atypical number lines".
These raw data consist of the estimates of a set of 20 target numbers (see column headings) on three different number lines: a 0-1000, a 367-1367, and a 1000-2000 number line (see Excel tabs) for a group of fifth graders and adults as specified in the age group column.
