Teaching Data to do Tricks

  • Recoding continuous data into bins

  • Operations on alphanumeric variables (string variables)

  • Generating test data

  • Taking random subsamples from a finite population

Recoding continuous data into bins

Symmetrical bins

If X >=0 and X<5 then bin=2;

if X >=5 and X<10 then bin=7;

if X >=10 and X<15 then bin=12;

if X >=15 and X<20 then bin=17;

if X >=20 and X<25 then bin=22;

if X >=25 and X<30 then bin=27;

Asymmetrical bins

If X >=0 and X<10 then bin=1;

if X >=10 and X<100 then bin=2;

if X >=100 and X<1000 then bin=3;

if X >=1000 then bin=4;
