Fig. 4.1 depicts the processes relating to the coding of the data from the articles reviews, and the methods of quantitative and qualitative analysis employed.



4.1 Data Coding

Data coding was carried out for the purpose of analysis and interpretation. The individual characteristics of each article commented upon by the reviewers (known as constructs) were collapsed into the five key dimensions as follows:

Accuracy:

This dimension represents the precision and correctness of the content of the article. It is computed by averaging the scores for validity, completeness, relevance, neutrality and currency.

References:

This represents the extent to which the article is adequately researched and referenced. It is calculated by averaging the scores for breadth and quality of references.

Style/ Readability:

Style/ readability represents the style and organisation of the article and the quality of the language, grammar, punctuation and visual aids used (if any). This dimension is computed by calculating the mean of the scores on conciseness, language, spelling and grammar, readability, enjoyment, clarity and organisation, coherence, photographs and pictures. 26
