5-Number Summary Calculation for the HP 42s

[cylurian]

Can someone help me with programming the 5-number summary for the HP 42s.

I'm working on two programs to calculate the 5-number summary using both the "Exclusive" and "Inclusive" methods. Usually, the TI calculators do the Exclusive method - meaning that they don't use the median to calculator Q1 or Q3. Here's a breakdown of what could happen.

Program 1: Exclusive Method
1. Create an nx1 matrix.
2. Sort the matrix in ascending order.
3. Identify the minimum and maximum values from the sorted matrix.
4. Determine if the dataset has an odd or even number of elements using a modulo operation.
5. Find the Median and Store it in M
6. Calculate Q1 and Q3:
- If the dataset is odd, exclude the median when dividing the data for Q1 and Q3.
7. Display the five-number summary: Min, Q1, Median, Q3, Max.

Program 2: Inclusive Method
1. Create an nx1 matrix.
2. Sort the matrix in ascending order.
3. Identify the minimum and maximum values from the sorted matrix.
4. Determine if the dataset has an odd or even number of elements using a modulo operation.
5. Find the Median
6. Calculate Q1 and Q3:
- If the dataset is odd, include the median when dividing the data for Q1 and Q3.
7. Display the five-number summary: Min, Q1, Median, Q3, Max.

Any guidance on how to implement this on an HP 42S calculator would be greatly appreciated!
