AP Statistics Calculator Hints
1: Edit
enters data into lists
2: Sort A
sorts data in ascending order (good for histograms and stem plots)
1: 1-var stats
gives descriptive statistics (
X , sx , n, min, Q1 , M , Q3 , max )
y  a  bx
8: LinReg (a + bx)
creates the linear regression equation
1: Z-test
Use ONLY if given
2: T-test
Use with 1-sample means
3: 2-SampZtest
Use ONLY if given
4: 2-SampTtest
Use with 2-sample means
5: 1-PropZTest
Use with 1-sample proportions
6: 2-PropZTest
Use with 2-sample proportions
7-B
Identical to 1-6 but using confidence intervals rather than hypothesis tests
C: X2–Test
Use when given a table and performing a Chi-Square test of Independence or Homogeneity
D: X2GOF–Test
Use when given a table and performing a Chi-Square Goodness of Fit test
F: LinRegTTest
Use with x-list and y-list for linreg t-test if not given Minitab output
G: LinRegTInt
Use with x-list and y-list for linreg t-interval if not given Minitab output

rather than s
 1 and  2 rather than s1 and s2
Allows you to paste the list of residuals…note to get the residuals you MUST run the regression first
Calculates the sum of the elements in a given list
Allows you to paste
y  a  bx
2: normalcdf
IF start in the y= list and have already separately calculated the regression equation
Calculates the probability for a certain region (area underneath a curve); type in (left boundary, right
boundary)
3: invNorm
Finds the z-score for a particular percentile; type in (proportion to the left of your boundary)
4: invT
Finds the t-score for a particular percentile or t* (upper critical value) for confidence intervals
involving the t-distribution; type in (proportion to the left of your boundary, degrees of freedom)
6: tcdf
Calculates the probability for a certain region (area underneath a curve) for a t-distribution; type in
(left boundary, right boundary, degrees of freedom)
8: χ2cdf
Calculates the probability for a certain region (area underneath a curve) for a χ2-distribution; type in
(χ2, right boundary…try 1000, degrees of freedom)
0: binompdf
Calculates binomial theorem probability for P(X = k); type in (n, p, k)
1: binomcdf
Calculates binomial theorem probability for P(X≤ k); type in (n, p, k) where k is the largest value of X
E: geometpdf
Calculates geometric probability for P(X = n); type in (p, n)
F: geometcdf
Calculates geometric probability for P(X ≤ n); type in (p, n) where n is the largest value of X
Calculates inverse log (good when working with exponential data)
1: Plot 1
Turn it on (enter takes you to the next menu)
6 graphs follow
Row 1: Scatterplot, Time Plot, Histogram
Row 2: Modified Box Plot, Box Plot, Normal Probability Plot
(Normal Probability Plot, aka Normal Quantile Plot, is useful when asked if your data
are normally distributed…enter the list number for your data…if this graph is linear,
then your
9: Zoom Stat
x-values are normally distributed.)
takes you to a nice window for statistics
Scroll to DiagnosticOn (turns on values such as r, r2 if your calculator is cleared)
