Your assignment is to prepare and submit a paper on report and analysis. Galton’s hobby was measurement. He wanted to count whenever and wherever he could. He measured arms, noses, legs, heights and weights. He made so many people wonder when he was teaching in his lectures. He is the man who classified the variations of attractiveness of women he met when he was walking on a street.
