Answer Key
Header labels for rows and columns
Section A: Quick Questions
Q1
A — Height_cm
Q2
B — True
Q3
B — Name, Age_years, Score_percent
Q4
A — Temperature_C
Q5
A — In the first row, above the data
Section B: Match the Pairs
Q1
Height_cm → A header label that names the data and includes its unit (centimetres)
Q2
A1: Name, B1: Age, C1: Score → One clear header label per column in the first row
Q3
Include the unit in a header so readers know how the numbers are measured → Weight_kg
Q4
Keep header capitalisation consistent across all columns → Name, Year_Level, Test_Score
Q5
A1: Data, B1: Data, C1: Data → The headers are vague and repeated, so they do not say what each column holds. Each column needs its own clear header such as Name, Age or Score.
Q6
A1: height_cm, B1: WEIGHT_KG, C1: Age → The capitalisation is inconsistent (lowercase, all capitals and capitalised first letter). Use one style such as Height_cm, Weight_kg and Age.
Section C: Definitions
Q1
header label — A label in the first row or column that names the data below or beside it. Use one per column, add units like Height_cm, and keep capitalisation consistent.Section D: Fill in the Blanks

Q1
B — The header Height does not say what unit the numbers are in. It should include the unit, like Height_cm.
Q2
C — The other headers use a capital letter at the start of each word. This one is all lowercase, so the capitalisation is inconsistent. It should be Score_Pct.
Q3
D — Each column should have only one header. This cell names two things. Year_born needs its own column and header, so D1 should be just Age_years.
Q4
D — Every column needs a header label in the first row. A blank header does not say what the data is. It should be Rainfall_mm.
Q5
A — The Price column has no header, so nobody knows what the numbers mean. The first row should say Price_AUD, with its unit.
