Building a coding frame for responses

A table of categories, each with a definition and example, so every response gets one consistent code. Categories do not overlap, and an Other category catches the rest.

Understanding Building a coding frame for responses in VCE Data Analytics U3O2

What it does: Each definition covers a separate idea with no overlap, so a response can be placed in exactly one category. Categories must be mutually exclusive. A response about price could fit both, so two coders might choose different codes. 'Other' makes sure every response gets a code, even unexpected ones. It should not become the largest group. Inconsistent coding usually means the definitions or examples are unclear. Fix the frame, not the data. 'Exercise' overlaps with walking and biking, and 'Public transport' overlaps with the bus, so the second set is not mutually exclusive. A coding frame row has a category name, a definition saying what belongs in it and an example, so every coder uses it the same way.

Common mistakes: Cost: food prices overlaps with category 1 (Food), so a response about food prices could take two codes. Categories must be mutually exclusive, so it should be 2 Price: cost of items. The Other category should only catch responses that fit no other category. Mentioning staff overlaps with category 2, so it should be 3 Other: fits no category.

Quick Questions

1. Which best describes a coding frame?

A. A table of categories, each with a definition and an example ✓

B. A list of every response in the order it was received

A coding frame sets out the categories, with a definition and example for each, so responses are coded the same way every time.

2. Two categories in a frame: 'Cost' and 'Money problems'. Is this a good frame?

A. No - the categories overlap, so they are not mutually exclusive ✓

B. Yes - more categories always make a better frame

Categories must be mutually exclusive. A response about price could fit both, so two coders might choose different codes.

3. Why does a coding frame include an 'Other' category?

A. To store responses the coder does not want to read

B. To catch responses that do not fit any other category ✓

'Other' makes sure every response gets a code, even unexpected ones. It should not become the largest group.

4. Why does each category in a coding frame have a definition and an example?

A. So different coders apply the same code to the same response ✓

B. So the frame looks longer and more detailed

Definitions and examples support consistent coding. Any coder should give the same code to the same response.

5. A response 'The app crashes and is too slow' fits two categories. What is the best fix?

A. Let each coder pick whichever category they prefer

B. Rewrite the category definitions so each response fits only one ✓

Clear, non-overlapping definitions mean every response gets exactly one code. Letting coders choose breaks consistent coding.

Match the Pairs

Category: Too expensive | Definition: Mentions price or cost | Example: "Lunches cost too much" → One row of a coding frame: a category with its definition and an example response

Category: Other | Definition: Any response that fits no other category → A catch-all category so every response gets a code, even unexpected ones

Categories must be mutually exclusive, so each response fits only one category → Price = mentions cost only | Quality = mentions taste or freshness only

Consistent coding means the same type of response always gets the same code → "Too pricey" -> PRICE | "Costs too much" -> PRICE | "Overpriced" -> PRICE

Cost = mentions price | Value = mentions price or quality → The categories overlap, so a response about price could be coded as Cost or Value. Categories must be mutually exclusive.

Price | Taste | Variety | (no Other category) → There is no Other category, so unexpected responses have nowhere to go and may be forced into the wrong category.

Key Term

coding frame

A table of categories, each with a definition and example, so every response gets one consistent code. Categories do not overlap, and an Other category catches the rest.

Fill in the Blanks

1. Code,Category,Definition,Example T,Transport,Bus or train problems,Bus late F,Food,Canteen food or prices,Too dear

Hint: Type the column heading that explains what belongs in each category.

2. Code,Category,Definition,Example F,Food,Canteen food or prices,Too dear O,Other,Fits no other category,Parking

Hint: Type the name of the catch-all category for responses that fit nowhere else.

3. T,Transport,Bus or train problems,Bus late F,Food,Canteen food or prices,Too dear Canteen is too dear -> Code: F

Hint: Type the single code from the frame that matches this response.

4. =COUNTIF(C2:C30,"T")

Hint: Type the function that counts how many coded cells match one code.

5. =IF(ISNUMBER(SEARCH("bus",B2)),"T","O")

Hint: Type the letter code, inside the quotes, given when no category matches the response.

Spot the Error

Question 1

A 1 Food: meals and snacks

B 2 Cost: food prices

C 3 Other: fits no category

Line B — Cost: food prices overlaps with category 1 (Food), so a response about food prices could take two codes. Categories must be mutually exclusive, so it should be 2 Price: cost of items.

Question 2

A 1 Wait time: queues, slow

B 2 Staff: friendly, rude

C 3 Other: staff, anything else

Line C — The Other category should only catch responses that fit no other category. Mentioning staff overlaps with category 2, so it should be 3 Other: fits no category.

Question 3

A FOR each response in survey

B IF text contains 'queue'

C code ← 1

D ELSE code ← blank

Line D — Every response must get a code. Responses that match no category should be coded 99 (Other), not left blank. It should be ELSE code ← 99.

Question 4

A Code|Name|Definition|Example

B 1|Price|About cost|too dear

C 1|Wait|About time|slow

D 3|Other|Fits none|n/a

Line C — Code 1 is already used by Price. Each category needs its own unique code so responses are coded consistently. It should be 2|Wait|About time|slow.

Question 5

A Categories: can overlap

B Each has a definition, example

C Other: catches the rest

Line A — Categories in a coding frame must be mutually exclusive, not overlapping, so each response fits only one. It should be Categories: mutually exclusive.
