AQA GCSE · Question 06.1 · Data Visualization and Representation
A vet keeps records of the mass and height of each animal he has registered. The table shows the masses and heights of 9 adult dogs which are of the Vizsla breed. The scatter graph shows the information for the first 6 dogs. Complete the diagram, plotting the points for the last 3 dogs.
A vet keeps records of the mass and height of each animal he has registered. The table shows the masses and heights of 9 adult dogs which are of the Vizsla breed. The scatter graph shows the information for the first 6 dogs. Complete the diagram, plotting the points for the last 3 dogs.
How to approach this question
1. Identify the data for the last 3 dogs from the table. These are (Mass, Height): (26.5, 65), (27, 65), and (27.5, 66).
2. For the first point (26.5, 65), find 26.5 on the x-axis (Mass) and 65 on the y-axis (Height). Mark the intersection with a cross.
3. Repeat for the second point (27, 65).
4. Repeat for the third point (27.5, 66).
Full Answer
The data for the last three dogs are:\n- Dog 7: Mass = 26.5 kg, Height = 65 cm\n- Dog 8: Mass = 27 kg, Height = 65 cm\n- Dog 9: Mass = 27.5 kg, Height = 66 cm\nThese correspond to the coordinates (26.5, 65), (27, 65), and (27.5, 66). We need to plot these points on the scatter graph using a cross.
Common mistakes
✗ Plotting the coordinates the wrong way round (e.g., (65, 26.5)).\n✗ Misreading the scales on the axes.
