Data Analysis Meaning

Defined as a series of operations to summarise collected data, organise it, and draw answers to research questions.
Aims to find relationships between groups.
Can also generate further research questions.

Data Analysis vs. Processing vs. Interpretation

Data analysis involves statistical tests and the process of finding relationships or significant differences in data.
Data processing involves preparing the data for analysis, including cleaning, coding, and inputting data into software.
Data interpretation involves drawing conclusions from the analysis results and comparing them to research questions or hypotheses.

Data Processing Steps

Editing: Checking raw data for errors, omissions, and inconsistencies.
Coding: Assigning numerals or symbols to data to create categories.
Classification: Grouping data into homogenous categories based on common characteristics.
Tabulation: Summarising raw data in a structured format like tables. This simplifies comparison and analysis.

Data Analysis Techniques

Descriptive analysis: Summarises and describes variables, such as frequencies, distributions, and averages.
Inferential analysis: Uses statistical tests to make inferences about a population based on a sample of data.

Statistical Analysis Tools

Measures of central tendency (mean, median, mode) are used for representing data.
Measures of dispersion (standard deviation) show the spread of data.
Measures of asymmetry (skewness) show the deviation from symmetry in data distribution.
Measures of relationship (correlation) show the relationship between variables.
Other tools like index numbers.

Tools for Data Analysis

Statistical Software Packages: SAS (Statistical Analysis System) and SPSS (Statistical Package for the Social Sciences).

Statistical Considerations

Statistical tools should be appropriate for the nature of the research.
Researchers should have comprehensive knowledge of analysis methods and tools.
Limitations of studies should be documented in the report.
Proper evaluation of facts is needed during data interpretation and analysis.

Diagrammatic Representations

Charts like bar diagrams, pie charts, etc. are used to illustrate data patterns visually.
