Contains the lower critical value of the experimental
variable associated with the negative TestScore value
which was calculated from the input α-level.
Contains the upper critical value of the experimental
variable associated with the positive TestScore value
which was calculated from the input α-level.
Contains the degrees of freedom for the t-tests.
Contains the probability associated with the TestScore
value.
For hypothesis tests, contains 0 or 1 to indicate rejection
or failure to reject the null hypothesis.
Contains the Z- or t-distribution value calculated from the
hypothesis test or confidence interval inputs.
Contains the value of the experimental variable
associated with the TestScore.
App functions are used by several of the HP Apps to
perform common calculations. For example, in the
Function app, the Plot view FCN menu has a function
called SLOPE that calculates the slope of a given function
at a given point. The SLOPE function can be used, from
the Home view or a program, etc. to give the same results
as if you were in the Function app Plot view. App
functions can be used to get the same results in a program
or the Home view or anywhere else- just as if you were in
the app. The App functions described in this section are
grouped by app.
The Function app functions provide the same functionality
found in the Function app's Plot view under the FCN
menu. All of these operations work on functions. The
functions may be expressions in X or the names of the
Function app variable F0 through F9.
Area under a curve or between curves. Finds the signed
area under a function or between two functions. Finds the
area under the function Fn or below Fn and above the
function Fm, from lower X-value to upper X-value.
