The purpose of the study is to develop a reliable computer-aided statistical instrument for data processing.
The researcher come up to the idea to formulate an executable program running in Microsoft Excel platform. The platform is chosen based on the fact that it is widely used office application and known to be user-friendly. EASIER or Executable Access to Statistics for Interactive and Efficient Research was born. Executable because the program can be run by a computer, it is accessible in terms that most teachers use MS Excel as an office application, it can solve and analyze most statistics problems, interactive because there is a two-way flow of information between a computer and the user which respond to a certain input, the system promise to achieve a maximum productivity with a minimum wasted effort or expense, and to establish facts and reach new conclusions.
The statistical instrument was evaluated by twenty-four (24) Senior High School Teachers from Nagcarlan, Liliw, Majayjay, Magdalena, Pila, Victoria, and Sta. Cruz district and six (6) College Teachers from Laguna State Polytechnic University Sta. Cruz Main Campus, and from Philippine Women’s University Sta. Cruz, Laguna.
It sought to answer the following questions: (1). What is the mean level of basic requirements of using computer-aided statistical instrument in terms of: 1.1 knowledge, 1.2 software and 1.3 hardware.? (2). What is the mean level of capability of EASIER as a computer-aided statistical instrument in computing statistical problems in terms of: 2.1 accepting input and data parameters, 2.2 organizing data, and 2.3 generating result, figures, charts, and drawing conclusion? (3). What is the mean level of acceptability of EASIER as a computer-aided statistical instrument in statistical analysis in terms of; 3.1 tool interface, and 3.2 operation and function? (4). Is there a significant difference between the level of responses of teachers from Senior High School and College instructors in terms of capability and acceptability of EASIER as a computer-aided statistical instrument?
