Sample Types of Data questions

A few of the 2 questions, from easier to harder. Choose your exam board and tier to practise them, with every answer marked.

Question 12 marksGrade 3-4
A survey records, for each person: (i) their favourite colour, (ii) their height in cm. (a) What type of data is 'favourite colour'? (b) What type of data is 'height'?
Show the worked solution
(a) Favourite colour is a category, not a number, so it is qualitative data. B1
(b) Height can be measured to any level of precision (e.g. 165.3 cm), so it is continuous data. B2
Question 21 markGrade 4-5
Jack constructs this grouped frequency table to record the masses, $m$ kg, of some parcels:
Mass, $m$

What are the common mistakes in Types of Data?

When a pupil makes one of these on Revision Workshop, the marking engine names the mistake and explains it, instead of just marking the answer wrong.

Treats discrete data as if it were continuous, or vice versa
Height can take any value in a range (e.g. 165.3 cm), so it's continuous, not discrete (discrete data can only take specific separate values, like a count)
Confuses qualitative categorical data with quantitative numerical data
A colour name isn't a number, so it can't be quantitative data, even though there might be several categories to choose from
Vague non specific explanation
Gave a vague comment about interval size instead of identifying the actual structural problems: a repeated/overlapping interval and a gap in coverage that leaves some possible masses with no interval to belong to.
