Expert writing Tips

Best practice

For academic writing, consider providing an additional identifier to the "two groups of", especially when comparing and contrasting their attributes. This helps readers follow your analysis. For example: 'Two groups of patients were compared: Group A (treatment) and Group B (control)'.

Common error

Avoid using "two groups of" when the reality is more nuanced. If the division is not strictly binary, consider alternatives like "several categories of" or "a range of" to reflect the complexity more accurately. Otherwise you may mislead the reader into thinking that the data split is straightforward, when it's not.
