Expert writing Tips
Best practice
When comparing two sets of data, use "are approximately the same" to convey that the differences are not statistically significant or relevant to the analysis. For example, "The average scores of the two groups are approximately the same, indicating that the intervention had no significant effect."
Common error
Avoid using "are approximately the same" when a more precise comparison is possible. If you have the exact values, use them instead of generalizing with "approximately the same". For example, if the values are 5.1 and 5.2, stating they "are approximately the same" is less informative than saying "the values are 5.1 and 5.2 respectively".
