10.computer technology in Research

  1. 1. Computer technologyD.A. Asir John Samuel, BSc (Psy), MPT (Neuro Paed), MAc, DYScEd, C/BLS, FAGE Lecturer, Alva’s college of Physiotherapy, Moodbidri Dr.Asir John Samuel (PT), Lecturer, ACP
  2. 2. Introduction to computers Generations Components usedFirst (1945-60) ValvesSecond (1960-65) TransistorThird (1965-70) Integrated Chips (IC)Fourth (1970-till now) MicroprocessorFifth (developing High Electron Mobilitystage……) Transistor Dr.Asir John Samuel (PT), Lecturer, ACP
  3. 3. Computer application in research• Model processing• Sample size calculation• Managing missing data• Performing computations• In estimating accurate p-value• Data analysis and interpretation Dr.Asir John Samuel (PT), Lecturer, ACP
  4. 4. Computer application in research Software Packages• SPSS – Statistical Package for Social Sciences• SAS – Statistical Analysis Software• Medcalc – Medical calculation Dr.Asir John Samuel (PT), Lecturer, ACP
  5. 5. 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 Dr.Asir John Samuel (PT), Lecturer, ACP
  6. 6. 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 Dr.Asir John Samuel (PT), Lecturer, ACP
  7. 7. 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 Dr.Asir John Samuel (PT), Lecturer, ACP
  8. 8. Computer and Researcher• Data organisation and coding• Storing the data• Selection of appropriate statistical measures/techniques• Selection of appropriate software package• Execution of the computer program Dr.Asir John Samuel (PT), Lecturer, ACP
  9. 9. 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” Dr.Asir John Samuel (PT), Lecturer, ACP
