# 35. PROCESS bootstrapping

## Purpose

Are the indirect and conditional effects in the agility mediation model stable under case resampling?

## Practice study

- File: [business-outcomes-observed.csv](../samples/business-outcomes-observed.csv)
- Observations: 500
- Data type: deterministic synthetic instructional data
- Complexity: a realistic multivariable observed-data analysis

**Prerequisites**

- Run the point PROCESS model first

## Exact procedure

1. Start QuickPLS and choose **New Project**. Enter a readable project name such as **PROCESS bootstrapping Tutorial** and choose a local `.qpls` destination.

2. Open **Data**, choose **Import Data**, select **business-outcomes-observed.csv**, keep the detected header row, review the preview, and choose **Import**. Confirm 500 observations are available.

3. This method does not require a latent-variable diagram. In its setup screen use these roles: Use the same X, mediator, moderator, outcome, controls, and graph as PROCESS/path analysis.

4. Review the selected outcome, predictors, groups, or analysis variables. Remove case_id and every unused teaching/reference column from the analysis selection.

5. Check that every required role is populated with a numeric variable and that outcome/predictor selections do not overlap.

6. Use **Calculate → Regression → Graph-defined Path Analysis / PROCESS, then enable Case-resampling bootstrap**.

7. Complete the method-specific settings:

- Use 1,000 resamples and a fixed seed
- Request two-tailed 95% intervals

8. Read **Readiness**, leave **Open Results when finished** selected, and choose **Start calculation** once. Wait for **Completed**; do not close the project while the result is being saved.

9. In **Results**, confirm **PROCESS bootstrapping** is selected and inspect these outputs in order:

1. Bootstrap direct and indirect effects
2. Conditional-effect intervals
3. Failure and usable-replicate accounting

10. Choose **Save Report** to preserve the exact result. Use **Export** for the needed table/report format. Close and reopen the project once and confirm the saved result remains selectable.

## Reading guidance

- The data are deterministic synthetic teaching data. They are suitable for reproducing the workflow, not for substantive publication claims.
