If you make a mistake entering data into your TI calculator, use
the arrow keys to move to the incorrect data and enter the
correct value. If you wish to delete an incorrect data point on a
TI-81, move the cursor to the “ ” for the x- or y-value of the
point and press
D
. Pressing
I
when the cursor is on the
“ ” allows you to insert a new data pair before that point. On
a TI-82, you can delete data by moving the cursor to the data to
be deleted and pressing
D
. To insert data at a desired point,
press
‹I
and enter the data.
Now that the data is entered, we can find the statistical values.

Chooses the standard deviation from the standard deviation
function menu that is already displayed and calculates.

Exits to the previous menu, enters the data sum function
menu, then chooses and calculates the sum.
¡e
Chooses the sum of the squares from the data sum menu that
is already displayed.

é
Notice that the TI calculators display many statistics at one time. x
_
denotes the
mean, x is the sum, x
2
is the sum of the squares, Sx is the standard deviation
of a population for which the data is a sample, x is the standard deviation of the
data given, and n is the number of data values. The TI-82 and TI-83 provide
additional statistical results.
To the nearest hundredth, the mean of the data is 50.85, the standard deviation is
12.59, the sum is 1017, the sum of the squares is 54,885, and the standard
deviation of a population for which the data is a sample is 12.92.
