Commonality of language

Using words the audience shares and understands, such as plain English and consistent terms, and avoiding jargon, slang and unexplained abbreviations.

Understanding Commonality of language in VCE Data Analytics U4O1

What it does: Consistent terms keep the language shared across a whole infographic or dashboard. Explaining abbreviations on first use means the audience, including EAL readers, can follow the message. Plain English that the audience shares is easy to understand. Stats jargon is not. Using the same term for the same thing stops readers wondering if these are different groups. Commonality of language is about words the audience shares, not words the writer likes. Idioms and slang are often confusing for EAL readers. Short, literal sentences are clearer. Short forms like 'Q3' can be unclear. Writing the full meaning helps everyone. Extra technical terms make the message harder to read. They do not improve commonality of language.

Common mistakes: The title uses unexplained abbreviations that Year 7 students may not understand. It should use full, plain words such as "Weekly Sales Report". "Gross txn vol" is jargon and an abbreviation that many readers will not know. It should use plain English, such as "Total sales".

Quick Questions

1. A dashboard is for Year 9 students and parents. Which label shows commonality of language?

A. Average mark out of 100 ✓

B. Mean SD of ordinal attainment

Plain English that the audience shares is easy to understand. Stats jargon is not.

2. A report uses the abbreviation 'KPI' for the first time. What is the best way to use it?

A. Write 'Key Performance Indicator (KPI)' the first time ✓

B. Use 'KPI' alone and expect everyone to know it

Unexplained abbreviations leave some readers behind. Spell the term out first, then use the short form.

3. Which is the better way to keep terms consistent in an infographic?

A. Switch between 'customers', 'clients' and 'punters'

B. Always call it 'customers' on every page ✓

Using the same term for the same thing stops readers wondering if these are different groups.

4. True or false: Using jargon is fine as long as the writer understands it.

A. True: only the writer needs to understand it

B. False: the audience must understand it ✓

Commonality of language is about words the audience shares, not words the writer likes.

5. Some of your audience are learning English as an additional language. Which wording suits them best?

A. Sales went up in March ✓

B. Sales went through the roof in March

Idioms and slang are often confusing for EAL readers. Short, literal sentences are clearer.

Match the Pairs

Plain English → Using short, clear words and sentences that most readers understand straight away

Jargon → Specialist words that only experts know, which can confuse an audience who do not share them

Use the same term for the same idea every time so readers are not confused → Always write 'customer' (not 'client', 'user' and 'buyer')

Spell out an acronym the first time it appears so every reader understands it → Key Performance Indicator (KPI)

Title: 'Q3 KPIs are lit, no cap' (for a community newsletter) → Uses slang and unexplained abbreviations, so many readers will not understand it

Legend: 'Cust' on one chart, 'Client' on another, 'Buyer' on a third → Uses different terms for the same idea, so readers may think they are three different groups

Key Term

commonality of language

Using words the audience shares and understands, such as plain English and consistent terms, and avoiding jargon, slang and unexplained abbreviations.

Fill in the Blanks

1. =SUBSTITUTE(A2,"DOB","Date of birth")

Hint: Type the function name that replaces an unexplained abbreviation in text with its full plain-English meaning.

2. =PROPER(TRIM(A2))

Hint: Type the function name that removes extra spaces so the same term is written consistently.

3. =VLOOKUP(A2,E2:F9,2,FALSE)

Hint: Type the column number that holds the plain-English meaning of each acronym in the lookup table.

4. ="Total students: "&COUNT(B2:B9)

Hint: Type the function name that counts the numbers, so the label reads clearly for any audience.

5. =IF(B2>=50,"Pass","Fail")

Hint: Type the comparison operator meaning 'greater than or equal to', so results use plain words rather than codes.

Spot the Error

Question 1

A title = "Wkly Sls Rpt Q3 FY"

B audience = "Year 7 students"

C print(title, audience)

Line A — The title uses unexplained abbreviations that Year 7 students may not understand. It should use full, plain words such as "Weekly Sales Report".

Question 2

A labels = []

B labels.append("Gross txn vol")

C labels.append("Total profit")

D print(labels)

Line B — "Gross txn vol" is jargon and an abbreviation that many readers will not know. It should use plain English, such as "Total sales".

Question 3

A title = "Survey Results"

B note = "Goal: 80% SLA per KPI"

C print(title)

D print(note)

Line B — SLA and KPI are acronyms that are not explained, so the audience may not understand them. Use plain words such as "Goal: 80% returned".

Question 4

A head = "Students by House"

B sub = "Students per Year"

C axis_label = "Learners"

D print(head, sub, axis_label)

Line C — The same group is called "Students" in the other labels but "Learners" here. Terms must be consistent, so it should be "Students".

Question 5

A title = "Sales Went Nuts!"

B audience = "Year 7 families"

C print(title)

Line A — "Went Nuts" is slang that not every reader will understand, especially those with English as an additional language. Use a plain title like "Sales This Term".
