TI-83 Plus: Timeplots

Exercise 1.138 (IPS 5/e, p. 97): Time plots

Generate a sequence into a list.

2^nd [LIST] 2^nd STAT

Right arrow Highlight OPS.

5 seq(

ALPHA [K]

,

ALPHA [K]

,

1966

,

1981

)

STO

2^nd [L2] seq(K,K,1966,1981)àL2

ENTER

(The second data set doesn’t have dates in sequence. If it did, we could save time by, e.g., 2^nd [ENTRY]

(i.e., 2^nd ENTER). Then edit the command (use the arrow and other keys) so that it reads seq(K,K,1967,1981)àL4.)

Enter the mean # young into list L3. STAT 1 (EDIT) …

Enter the dates of DDE measurement into list L4.

Enter the DDE, divided by 100 (for parts per 10⁸) into list L5. (Rescaled data)
