Total survey error: seven components on two tracks
The total survey error framework sorts every way a survey estimate can miss the truth into seven components on two tracks. Representation covers who you heard from: coverage, sampling, nonresponse and adjustment. Measurement covers what they told you: validity, measurement and processing. Each row gives the question to ask about your own study. Use it to plan where research effort goes, because a larger sample only reduces sampling error.

| Representation | Adjustment error | What did your weighting do? |
| Measurement | Validity | Does the question measure the concept you named? |
| Measurement | Measurement error | Did the respondent give an accurate answer? |
