Week 3 activity q 3.3

[Ajay Kumar]

We plan to have a three way classification for both frequency and length. There is now a medium frequency in addition to high and low; also, there is a medium length in addition to long and short. Given this setup, how many variables would we need to maintain to keep track of the word-counts for the different combinations that would come up?

 4

 6

 8

 9

I didnt undertand the question. Please explain?

THanks

See the attached picture, and see if you can understand.

The top table represents the 4 variables used to represent high-low frequency, and long-short length

The bottom table represents 9 variables used to represent high-medium-low frequency and long-medium-short length.  '

Essentially, these are the cross product of the two sets of values.

NOTE: I've renamed medium frequency and medium length to medum-f and medium-l to distinguish them.

This is the correct answer. Thanks for your explanation, Anand.
