Tips on reporting

  • Do not include every possible chart and frequency.
  • Think back to the key question of interest and answer this question.
  • Briefly talk about every chart and table you include but don’t discuss every number if the table is included.
  • Percentages should be rounded to whole numbers unless you are dealing with very small numbers e.g. 0.01%
