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%
