Quick Questions

Shade in the A or B circle for each question.

1. You are building a class sign-up form and want to test it. What is the safest data to use?

A Your classmates' real names and emails

B Fake data made by a data generator

2. Which statement describes fake test data?

A Real values with the names crossed out

B Invented values that look realistic, like 'Sam Taylor, age 13'

3. A data generator can quickly make 100 rows of names and numbers.

A True: you choose the fields and it fills in invented values

B False: you must type every row yourself

4. You made 50 rows of fake data in a generator. How can you use it in a spreadsheet?

A Export it as a CSV file and import it into the sheet

B Retype each row by hand into every cell

5. Why is fake data good for testing a new app that stores student details?

A If the app leaks or breaks, no real person is harmed

B Fake data makes the app collect more real data

Answer Key

Using generated fake test data

Section A: Quick Questions

B — Fake data made by a data generator

B — Invented values that look realistic, like 'Sam Taylor, age 13'

A — True: you choose the fields and it fills in invented values

A — Export it as a CSV file and import it into the sheet

A — If the app leaks or breaks, no real person is harmed

Section B: Match the Pairs

fake test data → Invented but realistic values, such as made-up names and numbers, used to build and test a solution

data generator → A tool that quickly creates many rows of invented names, ages and numbers for you to use in testing

Fake data can be exported from a generator as a file and opened in a spreadsheet to test your solution → students_fake.csv

A generator can make invented names and numbers so you never need real people's details to test → Name: Jordan Test, Age: 13, Score: 78

Test my quiz app by typing in my classmates' real names and marks → This uses real people's personal data for testing when invented data would work just as well.

Fake data = copy 50 real rows from the school list and change one letter → Changing one letter does not make data fake. The rows can still be traced back to real people.

Section C: Definitions

fake test data — Invented but realistic values made by a data generator, so you can build and test a solution without collecting any real person's data.

Section D: Fill in the Blanks

=RANDBETWEEN(12,15)

=CONCAT("S",RANDBETWEEN(100,999))

exportFile("fakeStudents.csv")

INSERT INTO students (firstName, points)
VALUES ('Test', 50);

IF testing THEN data ← fakeData
ELSE data ← realDataWithConsent

Section E: Spot the Error

B — The list of invented names is missing its closing bracket. It should be names = ['Ava', 'Liam', 'Mia'].

C — A CSV file separates values with commas, not semicolons. The row should be 2,Liam Test,14 so it matches the other rows.

B — This line pulls a real student's record, which defeats the purpose. The loop should use the generator: name ← randomName().

C — Python lists use append() to add an item, not add(). It should be rows.append(fake_name()).

B — Generated data should be exported as a CSV file so a spreadsheet can open it. The file name should be 'test.csv', matching line 3.
