New calculator programs offer statistical tests for comparing data groups. These tools are useful when t-tests are unsuitable, especially for non-normally distributed data or unequal variances.

Area of Science:

Biostatistics
Computational Statistics

Background:

Traditional statistical tests like t-tests have limitations.
T-tests are inappropriate for multiple comparisons or data with non-normal distributions and unequal variances.

Purpose of the Study:

To provide accessible calculator programs for statistical tests.
To enable researchers and students to perform advanced statistical analyses.

Main Methods:

Development of calculator programs for statistical tests.
Programs designed for Hewlett-Packard HP-11C programmable scientific calculator.

Main Results:

Programs facilitate statistical tests beyond standard t-tests.
These tests are applicable to non-normally distributed data and unequal variances.

Conclusions:

Calculator programs make advanced statistical tests more accessible.
Empowers students and investigators with powerful data analysis tools.
