Modern Computer Technology And Their Impact On Statistical Analysis

1.0 Introduction

1.1 Background Of The Study

This is the third guide concerned with the analysis of research data. The ideas apply whatever the method of data collection. They extend the methods described in the basis guides titled Approaches to the Analysis of survey data a modem approaches to the analysis of experimental data.

The previous guides were both concerned with methods of analysis that researchers should be able to handle themselves. They showed that a large proportion of the analysis often only involved descriptive methods. But research studies do normally includes some elements of generalizing form the sampled data to a larger population. This generalization requires the notions of “statistical inference” which are described in the guide confidence and significance key concepts of inferential statistics.

We first distinguish between “the modern approaches” that are outlined in the basic guides and the “modern methods” that we describe here. The former consists mainly of methods that were already available in pre-computer days some were not easy to apply without running into computational difficulties. Current computing software has taken away the strain and the methods can now be used easily.

The methods described in this guide are technically more advanced and are not practical without modern computer software. They are rarely applied in non- statistical research. We describe the most important of these methods and illustrate their uses. Our aim is to permit users to asses whether any of this method would be of valued for their analysis. We concentrate on two areas. These are modern exploratory tools applicable at initial stages of the analysis. Descriptive multivariate techniques, extensions of regression, modeling to generalized linear, models and multi level modeling techniques.

1.2 Statement Of The Problem

Here the statement of the problems includes the approaches to the analysis of survey data and analysis of experimental data. This generalization requires the notion of statistical inference which are described in the guide as confidence and significance being the key concepts of inferential statistics.

1.3 Research Question

This is one of a series of guides for research and support staff involved in natural resources projects. The subject matter here is modern computer. Technology and their input on statistical analysis.

1.4 Justification Of Study

This research is important to the readers and statisticians, as it reaches forth compendium on result of the research work carried on the modern methods of analysis.

To the readers who are opportune to read this research work, it will acquaint him/her on the modern methods of analysis.

To the statistician, the findings and recommendations will be a focus point each time they needs the modern methods of analysis in their work.

1.5 Scope Of The Study

The research work was gotten from the internet through the statistical good practice guidelines.

The work was studied in order to reduce constraint (limitations) that may limit the research work and we were able to generalize the entire work.

1.6 Objective Of The Study

Consequently upon the identified problems of this study, the research had the basis objective measures of;

To know the modern exploratory tools applicable at initial stages of data analysis

To know descriptive multivariate data techniques.
