    Fix: “The number increased by 10%.”
  • Mistake: “From 2020 until 2021, it rises.” (Sounds a bit off in chart language.)
    Fix: “From 2020 to 2021, it rose.”
  • Mistake: Using only “go up/go down” in formal writing.
    Fix: Mix in “increase/decrease,” “rise/fall,” “climb/drop.”
  • Mistake: Confusing percent with percentage points.
    Fix: “From 40% to 45% is up 5 percentage points.”
  • Mistake: Too many numbers with no story.
    Fix: Add structure: overall → key changes → comparison.
