Survey Frequencies is one of the statistical analyses applied automatically in MerQur. This page illustrates — on a Engineering sample dataset — how the analysis is run, what the MerQur output looks like, and how the result is reported in APA 7 format.

🎯 What is it for?

Survey Frequencies automatically performs all required assumption checks (normality, homogeneity of variance, etc.) for the relevant data type in the background and presents the results with a clear table + chart. Automatic interpretation to the APA 7 standard, effect sizes such as Cohen’s d/η²/R², and 95% confidence intervals are reported.

📌 When is it used?

  • Statistical analysis of measurements in the Engineering domain
  • To produce APA 7-compatible result tables for academic publications
  • Hypothesis testing and decision-making processes
  • Undergraduate / master’s / PhD theses after the appropriate method has been selected

📐 Assumptions

  • Appropriate scale — Variables must be at the measurement level required by the analysis (nominal/ordinal/interval/ratio)
  • Independent observations — Observations must come from individuals independent of one another
  • Sufficient sample size — The minimum n requirement for the analysis must be met
  • Outlier check — Outliers must be detected and evaluated

If assumptions are violated, MerQur automatically suggests a non-parametric or robust alternative.

📊 Sample Dataset — Engineering

ℹ Note: The scenario, MerQur output and interpretation below were produced by actually running the real example dataset in MerQur. Numeric results on your own data will differ; the goal is to show how the analysis is set up and interpreted end-to-end.

🎬 Example File

This analysis is demonstrated on the following example dataset for Engineering:

Muhendislik/79_survey_freq.xlsx

🎬 Scenario

We estimate category proportions of a categorical variable accounting for the design. For a complex sample, design-based frequency is appropriate.

⚙️ Variable Selection

  • Variables: yield_category
  • Weight: weight
  • Stratum: region

n = 400 · Columns: plot_id, region, yield_category, weight

📈 MerQur Output

SURVEY FREQUENCIES RESULT ───────────────────────────────────────────── weighted proportions + Taylor SE + 95% CI for yield_category categories (e.g. ‘high’ p_hat = 0.173, ‘high high’ p_hat = 0.074)

💬 Interpretation

We estimated the category proportions of a categorical variable (yield category) under sampling weights and stratification; each proportion has a design-based SE and confidence interval. Complex-sample frequency analysis, unlike a simple percentage, estimates population proportions without bias by accounting for the sampling design. In the field it is used to correctly report category distributions from regional representative samples.

⚠ Common Mistakes

  • Misidentifying the data type (e.g., loading a categorical variable as numeric)
  • Skipping assumption checks and going straight to the p-value
  • Failing to report effect size — APA 7 requires both p and effect size
  • Failing to apply a Type I error correction (Bonferroni/Tukey) in multiple comparisons
  • Not switching to a non-parametric alternative when n is insufficient
