TI-83 or TI-84 Calculator Instructions for Statistics
To enter data into a list
1. Choose STAT, EDIT, Edit
2. Enter the data into a vertical list (and remember the appropriate list
number (e.g., L2) for use later
To find descriptive statistics
1. Enter your data in a list
2. Choose STAT, then CALC, then 1-Var Stats
3. Enter the appropriate list (e.g., L1) and enter
It will look like: 1-Var Stats L1
To find probably from a normal distribution when asked to find
P(lower<X<upper)
1. Choose DISTR, normalcdf
2. Inside the parentheses, enter the following (in the following order):
Lower limit, upper limit, mean, stddev
It will look like: normalcdf (lower, upper, mean ,stddev)
(note that if z, mean=0 and stddev=1)
(note that is there is no lower limit, use negative infinity; if there is no
upper limit, use positive infinity)
To find x0 from a normal distribution such that P(X < x0)
1. Choose DISTR, invnorm
2. Inside the parentheses, enter the following (in the following order):
probability in a less than direction, mean, stddev
It will look like: invnorm (prob, mean, stddev)
(note that if z, mean=0 and stddev=1)
(note that if X, you must enter stddev/√n for stddev)
To find P(X=x) from a binomial distribution
1. Choose DISTR, binompdf
2. Inside the parentheses, enter the following (in the following order):
n, p, x
It will look like: binompdf (n,p,x)
