A survey researcher designs studies that turn people's opinions and behaviors into trustworthy numbers. The job is part writer, part statistician, part project manager. You will learn it in three stages: first the logic of good questions and samples, then the tools and workflow employers hire for (R or SPSS, Excel, weighting, reporting), then advanced methods like complex-sample variance, experiments in questionnaires, and managing teams. Everything below is free. Most jobs want a bachelor's and often a master's, so your portfolio of real, documented surveys matters as much as any credential.

Stage 1 of 3 · about 10 weeks
Understand how a survey works end to end and write clear questions, draw a simple sample, and describe results honestly.
Survey methodology basics and Total Survey Error
Every survey can go wrong in predictable ways: wrong people (coverage, sampling, nonresponse), wrong answers (measurement), wrong processing. Knowing this framework lets you spot problems before they cost a client money.
Questionnaire design
Wording drives answers. Double-barreled, leading or vague questions produce data that looks fine and means nothing.
Sampling basics
Sampling lets 1,000 people speak for millions, but only if selection is done by rules. You need to know simple random, stratified and cluster samples and what margin of error means.
Descriptive statistics and Excel
Most of your early work is cleaning data, making tables and checking numbers. Excel is on the job's software list and is where you will start.
Research ethics and confidentiality
You collect personal information. Informed consent, confidentiality and review boards are non-negotiable, and clients check for them.
Then 2 more stages (about 46 weeks in all) with lessons, drills, projects, 6 interview questions with strong answers and free resources.
