ChildFREQ

[Rasmus Bååth]

Hi Susan,

well the boring answer is that this is how the data looks. When you
change 12 into 6 the data points are shifted so that he first data
point that contained counts from 12-24 now contain counts from 6-18.
If you change the time resolution (group size) from 12 to 6 you will
see how the word count is distributed at a higher resolution, here you
will also see that the graph is more uneven. When using ChildFreq one
should be aware that there is not much data for very young and very
old children, thus count data from them is quite unreliable. How many
word tokens the tokens/1000,000 measure is based om is reported in the
table below the graph.

I hope this answered your question!

When I graphed it for 6 months to 71 months, however, the graph was uneven for the 12 to 71 part that had been smooth. Why did the graph change? Thank you Rasmus.

The site is located athttp://childfreq.sumsar.netand there is now a link to this site and the PDF of the paper describing the system from the CHILDES home page.  Many thanks to Rasmus for contributing this valuable method of analyzing and exploring lexical patterns.
