INTRODUCTION
Statistics is credible. The utilization of statistics in the field of education, business, commerce, and offices played a significant role in the exponential growth and economic development. Today, programming is a way to create presentations where one needs to express numerically -a factor for effective communication in the cyber world. Researches and innovations use statistics for scientific literacy, the strong command of research and development requires an innovative process to express data in the most convenient way. In this study, programming of statistical software (Chi-square andT-test) aids the students to compute and analyze data. Hence, student-friendly software was developed.
METHODS
This study uses descriptive quantitative research design. The creation of the Programmed Chi-Square and T-Test (PCAT) Software needed formulae and codes for input in Visual Studio and Database Management through the help of an IT programmer. PCAT demonstration was first conducted. System Usability Scale was used to collect data coming from 45 students of Grade 9 to 12; 5 science and mathematics teachers were also included as respondents of the survey.
RESULTS
To calculate the SUS score, odd number questions in the questionnaire is scaled position minus one, while for the even number questions, is 5 minus the scale position. Multiply the sum of the scores by 2.5 to obtain the overall value of system usability. From the SUS scores gathered, 71.64 from Grade 9 scores 65, Grade 10 scores 78.5, grade 11 scores 69.7, grade 12 scores 73.5 and teachers' scores 71.5. With that said, scores above 68 are considered above average that is qualified for system usability.
DISCUSSIONS
The use of system usability scale labeled the strengths and weaknesses of the software. From the scale of71.64 that is greater than 68 of passing score concluded that the Proposed Chi-square andT-test software is accepted as useful by the respondents and researchers.
