The purpose of the study was to provide the necessary statistical information in order to facilitate access to the vast potential of Microsoft Excel correctly.
USING EXCEL FOR DATA ANALYSIS SOFTWARE
The software that use spreadsheets are fundamental in different scientific fields but require an understanding of basic mathematical concepts that regulate the operation. This makes it particularly easy to insert and/or modify data previously collected within certain sectors such as occurs in research studies.
USING EXCEL FOR DATA ANALYSIS UPDATE
The spreadsheet arises from the need to modify, through a specific “software”, a certain amount of data with the ability to automatically update the results deriving from the analysis of these without reprogramming entire columns of calculation. The mathematical concepts presented in this discussion represent the basis of the statistical models used in platforms of spreadsheets. The first step of statistical work is the collection of data, which, if well organized, saves effort in subsequent operations and allows the correct setting for the analysis. The term “Statistics” was introduced in the seventeenth century with the meaning of “science of the state” ( 1), which aims to gather and sort information to the public administration regarding: size and composition of the population, migration, demographic changes, birth and mortality tables, data on businesses, crops, the distribution of wealth, education and health. In this sense, statistical analysis plays a central role. The value of a scientific study is recognized by the community only if it is supported by numerical evidence that warrants the validity.
