That is to say, once dispersion seems to play a role in learning, the next step is to transform the former into figures, so that we can answer questions such as how many words per hour

The idea that a substantial vocabulary gap separates more and less affluent children comes from the groundbreaking research of Hart and Risley (1995; 1999; 2003) who observed 42 families of varied socioeconomic backgrounds and found that by age 3 children from low-income families had heard just half as many words as children from working-class families (616 words per hour
Remember, in Napoleon's time communications took place at the pace of the hand-scrawled note, a rate of transmission of words per hour

Her fastest writing pace of 50 words per hour

The results showed that by age three, children of professional parents were hearing on average 2,153 words per hour
, compared with the 616 words per hour

We then had to estimate bytes and words per hour
of game play.
By contrast, adults typically utter approximately 941 words per hour
. There were also significant reductions in child vocalizations.
"Adults typically utter approximately 941 words per hour
. Our study found that adult words are almost completely eliminated when television is audible to the child.
I calculate that to complete a first draft in two months, Bauby would have had to dictate 135 words per hour
