Reviewer 2 wants mean age by treatment group. In SPSS, how do you start building that methods table?
I'd open the dataset, run Descriptives by group, screenshot the output, type the numbers into my Word doc by hand.
In Python, those numbers are variables. age = 29.0 is a named slot — the same idea as a pre-registered hypothesis placeholder. The name doesn't disappear when you close the file; it's there for the next wave, the next revision request, the next reviewer. Then you combine variables into a label with an f-string:
respondent_id = "R_042"
age = 29.0
label = f"Respondent {respondent_id} — Age: {age:.2f}"
What does :.2f actually do? I see it everywhere but I'm not sure I understand it.
The colon opens the format spec. 2f means: float, two decimal places. So 29.0 becomes 29.00 and 34.2 becomes 34.20 — consistent precision across every row, exactly what a methods table requires.
Oh — and I can wrap this in a function so I call it for every respondent, not just R_042.
Pre-registered hypothesis slot that does arithmetic and formats LaTeX table rows. That's all a variable is:
def format_respondent(respondent_id: str, age: float) -> str:
result = f"Respondent {respondent_id} — Age: {age:.2f}"
print(f"Formatted: {result}")
return result
I've spent years copying numbers into Word. This is embarrassingly straightforward by comparison.
That's the right reaction. Forget the f prefix and {respondent_id} prints literally as a string of characters. Forget :.2f and 29.0 stays 29.0, not 29.00. Both are silent bugs — no error raised, just wrong output that only surfaces when a co-author spots the inconsistency.
A variable is a label attached to a value. age = 29.0 creates a float; respondent_id = "R_042" creates a str. Python infers the type — no declaration needed.
Prefix any string with f and embed variables inside {}. A spec after : controls numeric shape:
| Spec | Example | Output |
|---|---|---|
:.2f | f"{29.0:.2f}" | 29.00 |
:,.2f | f"{1250.0:,.2f}" | 1,250.00 |
:>6 | f"{7:>6}" | 7 |
f prefix — "{age}" prints literal braces. Silent bug, no error.:.2f — 29.0 renders as 29.0, inconsistent with 34.20.= vs == — assignment vs. comparison.Reviewer 2 wants mean age by treatment group. In SPSS, how do you start building that methods table?

Write `format_respondent(respondent_id, age)` that returns a string like `"Respondent R_042 — Age: 29.00"` using an f-string with `:.2f` formatting — for example, `format_respondent("R_042", 29.0)` should return `"Respondent R_042 — Age: 29.00"`.
