Starting data analysis is less about choosing one “best” software and more about building a reliable workflow. Whether you use STATA, R, or both, the goal is the same: transparent steps from raw data to interpretable results.
Begin with a Question, Not a Command
Before coding, define:
- Primary research question
- Key outcomes and explanatory variables
- Unit of analysis (individual, household, firm, village)
- Time frame and comparison strategy
Clear analytical scope prevents random variable hunting and inconsistent models.
Organize Your Project Early
A simple structure saves time:
raw_data/(never edited)data/clean/scripts/outputs/tables/outputs/figures/docs/
Keep raw files untouched and produce all derived files through scripts.
Core Workflow for Beginners
- Import and inspect: variable names, types, missingness
- Clean systematically: duplicates, labels, coding consistency
- Explore: summary statistics and basic visuals
- Model carefully: start simple, then add complexity
- Report transparently: assumptions, uncertainty, limitations
Skipping exploratory checks is one of the most common causes of avoidable mistakes.
Minimal STATA Start
* Load data
use "data/raw/survey_data.dta", clear
* Inspect structure
describe
summarize
* Check missingness and duplicates
misstable summarize
duplicates report household_id
* Create one documented derived variable
gen ln_income = ln(income) if income > 0
Minimal R Start
library(tidyverse)
library(haven)
df <- read_dta("data/raw/survey_data.dta")
glimpse(df)
summary(df)
# Example derived variable
df <- df %>%
mutate(ln_income = if_else(income > 0, log(income), NA_real_))
Good Habits That Scale
- Use explicit variable names
- Comment why a step is needed
- Save intermediate datasets with clear names
- Keep one script for data construction and one for analysis
- Re-run from top before sharing results
If your script fails when run from a clean session, the workflow is not yet stable.
Interpreting Results Responsibly
Strong analysis is not just statistical significance. Ask:
- Is the effect size meaningful?
- Are results robust to reasonable specification changes?
- Are limitations clearly stated?
- Does the interpretation stay within the design’s causal limits?
A Practical Benchmark
A solid beginner analysis is one that a colleague can run, understand, and audit without asking for hidden steps. Reproducibility is not advanced polish; it is baseline quality.
