Level 5-6 Data Handling - Quantitative Data

1. If data can only take certain numerical values it is called discrete. Which of these types of data is discrete?

   • The colour of an apple
   • The number of pips in an apple
   • The volume (in cm³) of an apple
   • The weight (in g) of an apple

2. If data can be measured against a scale it is called continuous. Which of these types of data is continuous?

   • The beds in wards of a town's hospital
   • The heights of buildings in a town
   • The names of roads in a town
   • The number of pupils in a town's schools

3. Adults responding to a survey are asked to choose their age group from these: 18-25, 25-40, 40-60, over 60. What is wrong with this choice?

   • No ages below 18
   • Age group intervals are all different
   • Intervals overlap
   • 'Over 60' is too vague

4. Which of these can be read from a grouped frequency table of children's heights (h cm) recorded in 10cm intervals?

   • Heights of individual children
   • The height range
   • The median height
   • The modal height interval

5. The frequency recorded in the interval 130 < h ≤ 140 is 5. This means that five children are .......

   • at least 130cm tall
   • less than 140cm tall
   • 135cm tall
   • over 130cm and up to 140cm tall

6. Which of these intervals would include a height of 130cm?

   • 125 ≤ h < 130
   • 130 < h ≤ 140
   • 120 < h ≤ 130
   • h >130

7. The contents of seed packets are recorded to the nearest 10. A pack with 43 seeds is recorded as having .......

   • 30 seeds
   • 35 seeds
   • 40 seeds
   • 45 seeds

8. A packet of 50 seeds (to the nearest 10) will contain at least .......

   • 44 seeds
   • 45 seeds
   • 54 seeds
   • 55 seeds

9. The contents of 20 packets of seeds (to the nearest 10) are: 5 x 30, 9 x 40, 5 x 50, 1 x 60. What is the best estimate for the total number of seeds in these packs?

   • 630
   • 750
   • 820
   • 940

10. The contents of 20 packets of seeds (to the nearest 10) are: 5 x 30, 9 x 40, 5 x 50, 1 x 60. What is the best estimate for the mean (average) contents of these seed packets?

    • 41
    • 42
    • 43
    • 44
