Subject Scale (Large) Scale (Small)
Number Greater Smaller/ Fewer
Ratio Higher Lower
Percentage Higher Lower

Vocabulary to show the sequence

  • Subsequently, Respectively, Consecutively, Sequentially
  • Previous, Next, First, Second, Third, Finally, Former, Latter

“The market shares of HTC, Huawei, Samsung, Apple and Nokia in 2010 were 12%, 7%, 20%, 16% and 4% globally.”

This above sentence makes it ambiguous to understand which mobile brand had what percentage of market share. If there are more than 2 values/ figures, you should always use “consecutively/ sequentially/ respectively”. Using either of these words would eliminate any doubt about the above sentence as it will clearly state that the percentages of market shares mentioned here would match the mobile brands sequentially (i.e. first one for the first brand, the second one for the second brand and so on.)

“The market shares of HTC, Huawei, Samsung, Apple and Nokia in 2010 were 12%, 7%, 20%, 16% and 4% respectively in the global market.”

Note: You do not need to use “consecutively/ sequentially/ respectively” if there are only two values to write.

Vocabulary to show transitions

Vocabulary to describe different types of data/trends in a paragraph while showing a smooth and accurate transition is quite important. Following word(s)/ phrase(s) would help you do so in an excellent way…

  • Then
  • Afterwards
  • Following that
  • Followed by
  • Next
  • Subsequently
