D'Agostino Pearson Test: Assumptions, Interpretation, SPSS, Python, R and Excel Guide
This guide explains D'Agostino Pearson Test using the verified files in this folder: 7 Python chart(s), 7 R chart(s), and 1 SPSS PDF output file(s). It follows the same live Salar Cafe post structure used by the most recent published guides.
Quick Answer: D'Agostino Pearson Test
D'Agostino Pearson Test is interpreted by comparing the reported test statistic and p-value with the chosen alpha level. When p is below alpha, the assumption or null hypothesis is treated as statistically inconsistent with the data.

What Is D'Agostino Pearson Test?
D'Agostino Pearson Test is used in statistical analysis to summarize evidence, check assumptions, or support a decision about a variable, model, or distribution. The safest interpretation combines the numerical result, chart pattern, sample context, and research question.
In this guide, the same topic is demonstrated through SPSS output, Python charts, R charts, and an Excel-friendly workflow so that the result can be checked across tools.
D'Agostino Pearson Test Formula and Decision Rule
D'Agostino Pearson Test is interpreted by comparing the reported test statistic and p-value with the chosen alpha level. When p is below alpha, the assumption or null hypothesis is treated as statistically inconsistent with the data.
For assumption tests, the usual reporting rule is to compare the p-value with alpha, commonly 0.05. For descriptive measures, the statistic should be interpreted with the scale of the original variable.
Dataset and Verified SPSS Results for D'Agostino Pearson Test
The SPSS PDF output is the verification file for this post. It should be used to confirm the reported statistic, decision, and interpretation before the result is used in a report or assignment.

SPSS Workflow for D'Agostino Pearson Test
Open the dataset, run the relevant SPSS syntax or menu procedure, export the output to PDF, and compare the statistic, p-value, chart pattern, and written decision.
Python Workflow for D'Agostino Pearson Test
Use pandas for data handling, scipy or statsmodels for the statistic where needed, and matplotlib or seaborn for the diagnostic charts. The Python chart files above show the visual checks generated for this folder.
R Workflow for D'Agostino Pearson Test
Use base R, tidyverse, ggplot2, and the relevant statistical package for the method. The R chart files above provide an independent visual check against the Python output.
Excel Workflow for D'Agostino Pearson Test
Excel can support the same interpretation by organizing the dataset, applying formulas or add-ins, and checking chart patterns. For formal reports, verify Excel results against SPSS, Python, or R output.
APA and Report Writing for D'Agostino Pearson Test
Report the statistic, sample context, decision rule, and practical interpretation. When a p-value is involved, state whether the result is statistically significant at the chosen alpha level and avoid overstating the conclusion.
A concise reporting sentence is: The D'Agostino Pearson Test output was reviewed using SPSS and cross-checked with Python and R charts; the result was interpreted using the statistic, p-value or scale, and the observed chart pattern.
