ABSTRACT
In the frequency distribution, the frequencies are added up and percentages added. This is a common way of presenting a frequency distribution. The percentages indicate the proportion of times that a particular age is recorded. Proportions can be expressed as decimals or multiplied by 100 and expressed as percentages. Proportions or percentages are more useful than frequencies when we want to compare numbers of events in two or more groups of unequal size. In company A, there have been 37 accidents among a total of 267 workers. In company B, 45 accidents have occurred among a total of 385 workers. At which company are workers more likely to have an accident? Company A had 37 accidents among 267 workers – the proportion of accidents is 0.139 (37/267). Company B had 45 accidents among 385 workers – the proportion of accidents is 0.117 (45/385).
