ABSTRACT

Closer scrutiny of the horizontal bar chart shows that approximately 25 per cent (29) of graduates who obtained a first class degree graduated in engineering compared with only 18 per cent (21) in the social sciences. The highest percentage of first class graduates came from physical sciences (54 per cent, n=62). Note it is good practice, whenever percentages are used, to provide the base figure on which the percentage is based here 100 per cent=114. The width of the bars has no significance in a bar chart (unlike in a histogram-see later).
