Use of Computers in Research

1. Computer technology Dr.Asir John Samuel (PT), Lecturer, ACP

2. Dr.Asir John Samuel (PT), Lecturer, ACP Computer application in research Model processing Sample size calculation Managing missing data Performing computations In estimating accurate p-value Data analysis and interpretation

3. Dr.Asir John Samuel (PT), Lecturer, ACP Computer application in research Software Packages SPSS – Statistical Package for Social Sciences SAS – Statistical Analysis Software Medcalc – Medical calculation

4. Dr.Asir John Samuel (PT), Lecturer, ACP Computer and Researcher Performing calculation at the speed of light Data analysis concerning large research projects Huge storage of data Faster retrieval Added quality to research activity Trial and error process frequently employed

5. Dr.Asir John Samuel (PT), Lecturer, ACP Computer and Researcher Can easily calculate computation of means, SD, correlation coefficients, ‘t’ tests, analysis of variance, multiple regression and various nonparametric analyses Multivariate analysis can be computed Only work of researcher is to feed in the data

6. Dr.Asir John Samuel (PT), Lecturer, ACP Computer and Researcher Facilitate research work Innumerable data can be processed and analyzed with greater ease and speed Results obtained are accurate and reliable Pictorial graphing and reporting

7. Dr.Asir John Samuel (PT), Lecturer, ACP Computer and Researcher Data organisation and coding Storing the data Selection of appropriate measures/techniques statistical Selection of appropriate software package Execution of the computer program

8. Dr.Asir John Samuel (PT), Lecturer, ACP Limitation of computer-based analysis Requires expensive computerised analysis setting, collection and feeding of data (GAITRE) Not economical in case of small projects Various small details which are not fed into computers may get lost Does not think only execute “Garbage in, garbage out”
