What is the mean value of these IQ values? r gap_numeric(mean(iq))

See ?gap_numeric for more options (e.g. tolerance).

text gaps

The original IQ test was developed by r gap_text(c("Alfred Binet", "Binet", "A. Binet")) in the early <<20th>> century with the intention of identifying students who might need extra assistance.

See ?gap_text for more options (e.g. tolerance).
