Tutorial
Section 3: Usage 
​

Usage refers to the way that we use words. For example, when is it proper to use affect as opposed to effect? Likewise, when should you select continual and when you choose continuous? With technical reports and journal papers, another challenge for usage concerns the correct verb tense--for instance, whether to select "The results showed..." as opposed to "The results show...." Still another important aspect of usage for engineers and scientists is whether to use numerals or to write out numbers.
