1. “Pinpoint the Trends of Tablet Market Shares”“Analyze the Trends in Tablet Market Shares”

    • Reason: “Pinpoint” is not the best verb in this context. “Analyze” is more appropriate for a report.
  2. “within the years 2010, 2011 and 2012”“between the years 2010 and 2012”

    • Reason: “Within the years” is incorrect; “between” is the proper preposition when referring to a range of years.
  3. “it’s easier to use and it’s more compact”“it is easier to use and more compact”

    • Reason: Contractions (“it’s”) should not be used in formal reports. Also, “it is” does not need to be repeated.
  4. “you can use it at most places.”“it can be used in most places.”

    • Reason: More formal and impersonal phrasing is better for reports.
  5. “market share was mainly consisting of”“market share mainly consisted of”

    • Reason: “Was mainly consisting of” is grammatically incorrect. “Mainly consisted of” is the correct past tense form.
  6. “Apple had 82% Market Share, Samsung 11% and PC OEMs had 1% the other 6% where shared by unfamiliar brands.”
    “Apple had 82% market share, Samsung had 11%, and PC OEMs had 1%. The remaining 6% was shared by unfamiliar brands.”

    • Reason: The original sentence has incorrect capitalization, a missing verb, and improper use of “where” (should be “was”).
  7. “A year later in 2011 the market share from Apple and Samsung went down to 65% and 8%”
    “A year later, in 2011, Apple’s market share declined to 65%, and Samsung’s decreased to 8%.”

    • Reason: “Market share from Apple and Samsung” is awkward. “Declined” and “decreased” are better verbs for data trends.
  8. “The only brand that didn’t change was Nokia, still sharing 0% of the market.”
    “The only brand that did not change was Nokia, which continued to have 0% market share.”

    • Reason: “Didn’t” should be changed to “did not” for formality. “Sharing 0% of the market” is awkward; “continued to have 0% market share” is clearer.
  9. “In 2012 Apple shrunk by 8%”“In 2012, Apple’s market share decreased by 8%”

    • Reason: “Shrunk” is informal; “decreased” is more appropriate for a report.
  10. “Overall, the tiny brands increased in market share.”“Overall, smaller brands gained market share.”

  • Reason: “Tiny brands” is too informal; “smaller brands” is more professional. “Gained market share” is more precise.
  1. “it would be the best to focus on Apple and Samsung”“it would be best to focus on Apple and Samsung”

    • Reason: “The best” is incorrect here; “best” alone fits better.
  2. “as the market share of rather smaller brands might rise over the years.”
    “as the market share of smaller brands may increase over time.”

    • Reason: “Rather smaller brands” is unnatural. “May increase over time” is more formal and clear.
  3. “tables”“tablets”

  • Original: “The main reason why people prefer tables to PCs and laptops…”
  • Correction: “The main reason why people prefer tablets to PCs and laptops…”
  • Reason: “Tables” is incorrect; the intended word is “tablets.”
  1. “Tables have also a longer battery life than laptops.”“Tablets also have a longer battery life than laptops.”

    • Reason: Incorrect word order; “also” should come before “have” for proper sentence structure.
  2. “percent””% (for consistency)

    • Original: “82 percent of customers bought Apple tablets and 11 percent bought Samsung tablets.”
    • Correction: “82% of customers bought Apple tablets and 11% bought Samsung tablets.”
    • Reason: While “percent” is not necessarily wrong, using ”%” is more consistent with numerical data presentation in reports.
  3. “To have a variety of tablets is important”“Having a variety of tablets is important”

    • Reason: The original phrase is grammatically awkward. Using a gerund (“Having”) makes the sentence more natural.
  4. “its good”“it is good”

    • Original: “…so its good to have other cheaper brands in stock.”
    • Correction: “…so it is good to have other, cheaper brands in stock.”
    • Reason: “its” (possessive) should be “it is” (contraction not used in formal reports).
  5. “prices classes”“price classes”

    • Original: “…so its important to have a variety of tablets.”
    • Correction: “…so it is important to have a variety of tablets.”
    • Reason: “prices classes” is incorrect; “price classes” is the correct term. Also, “its” should be changed to “it is” for formality.
