The MATH200Z subprogram is called by MATH200A and MATH200b, and you’ll never run it directly. If you want to know how to use those programs, please see MATH200A Program — Basic Statistics Utilities for TI-83/84 and MATH200B Program — Extra Statistics Utilities for TI-83/84.
MATH200Z presents common dialogs for getting data and confidence levels, and validates the user’s input. The calling program sets the variable θ to tell MATH200Z what to do. This document shows what MATH200Z does with each value of θ and what variables it sets for use by the calling program.
The operation of the program depends on the user’s selected data arrangement, as follows:
Plain List | Ungrouped dist | Grouped dist | Discrete PD | Binomial PD | |
---|---|---|---|---|---|
θ set to | 0 (unchanged) | 1 | 2 | 3 | 4 |
User asked for | data list | data list, freq list | class midpoints, freq list | data list, probabilities | number of trials, prob of success |
List LD set to | data list, must have ≥4 entries | data list, must have 2–47 entries equally spaced | class midpoints, must have 2–47 entries equally spaced | data list, must have 2–47 entries equally spaced | sequence, 0 through number of trials (max 46) |
W set to | (unchanged) | class width, and variable X is used as a loop index | 1 | ||
List LF set to | (unchanged) | frequencies or relative frequencies, must add to a whole number ≥4 | probabilities, must add to 1 | binomial probabilities | |
must have same number of entries as LD | |||||
N set to | number of data points in LD | sum of LF | sum of LF (sum = 1) | ||
X set to | (unchanged) | nothing useful |
The operation of the program depends on the user’s selected data arrangement, as follows:
Plain List | Ungrouped dist | Grouped dist | Discrete PD | Binomial PD | |
---|---|---|---|---|---|
θ set to | 10 (unchanged) | 11 | 12 | 13 | 14 |
User asked for | data list | data list, freq list | class midpoints, freq list | data list, probabilities | number of trials, prob of success |
List LD set to | data list, must have ≥4 entries | data list, must have ≥2 entries | class midpoints, must have ≥2 entries equally spaced | data list, must have ≥2 entries | sequence, 0 through number of trials |
W set to | (unchanged) | (unchanged) | class width, and variable X is used as a loop index | (unchanged) | 1 |
List LF set to | (unchanged) | frequencies or relative frequencies, must add to a whole number ≥4 | probabilities, must add to 1 | binomial probabilities | |
must have same number of entries as LD | |||||
N set to | number of data points in LD | sum of LF | sum of LF (sum = 1) | ||
X set to | (unchanged) | (unchanged) | nothing useful | (unchanged) | nothing useful |
The operation of the program depends on the user’s selected data arrangement, as follows:
Plain List | Ungrouped dist | |
---|---|---|
θ set to | 20 (unchanged) | 21 |
List LD set to | data list, must have ≥4 entries | data list, must have ≥2 entries |
List LF set to | (unchanged) | frequencies or relative frequencies, must add to a whole number and must have same number of entries as LD |
N set to | number of data points in LD | sum of LF |
