Use this skill for ADS/ADS2 one-way ANOVA, two-way/factorial ANOVA, interaction effects, Tukey HSD post-hoc tests, ANOVA assumption checks, numeric response by categorical factors, tooth-growth vitamin C designs, and ANOVA power. Trigger on ANOVA, aov, Tukey, interaction, factorial, two-way, dose and treatment, supplement, or numeric outcome across groups.

Use this skill for ADS/ADS2 categorical data, chi-square goodness-of-fit, chi-square independence or homogeneity, Fisher exact test, Mendelian ratios, genotype/survival counts, satisfaction tables, expected counts, CrossTable usage, ordinal categorical choices, and categorical plots. Trigger on chi-square, chisq.test, Fisher, categorical, counts, contingency table, Mendelian, genotype, survival, satisfaction, homogeneity, independence, or goodness-of-fit.

Use this skill for ADS/ADS2 k-means clustering, neuron-type classification from numeric features, comparing clusters to known labels, elbow plots, adjusted Rand index, simple feature extraction from image-like matrices, MNIST-style row/column summaries, or classification feature preparation. Trigger on kmeans, k-means, clustering, neuron type, hap1, hap2, feature extraction, MNIST, pixels, classification, or cluster validation.

Use this skill as a final ADS/ADS2 exam answer review checklist. It catches common mistakes in data cleaning, test choice, paired designs, ANOVA interactions, chi-square expected counts, pwr sample-size formulas, regression wording, clustering interpretation, and report language. Trigger on review my ADS answer, check mistakes, before submission, common traps, is this correct, or final checklist.

Use this skill for ADS/ADS2 correlation, simple linear regression, multiple regression, regression assumptions, residual diagnostics, slope interpretation, R-squared, nested model comparison, interaction terms, VIF/multicollinearity, time-window/local regressions, and ICA trend modeling. Trigger on correlation, cor.test, regression, lm, slope, residuals, R-squared, model comparison, VIF, trend, predictor, or association.

Use this skill for ADS/ADS2 exam data import, checking, cleaning, reshaping, typo correction, missing values, duplicates, factor conversion, paired-data merging, or preparing data for R statistical tests. Trigger when the user says clean data, check NA, duplicates, typo, reshape long/wide, pivot, gather, merge before/after, or "import and organize the data".

Use this skill whenever the user is answering an ADS/ADS2 coding challenge, online problem-solving exam, or ICA-style RMarkdown report and needs the overall answer structure. Trigger on ADS exam, ADS2 exam, coding challenge, RMarkdown exam answer, ICA report, "how should I write the answer", or when multiple statistical tasks must be presented coherently.

Use this skill for ADS2 ICA or open-ended analysis reports, especially substance_use.csv, Global Burden of Disease data, filtering by measure/location/sex/age/cause/year, trend plots, age/sex comparisons, asking an original question, reproducible RMarkdown, and interpreting observational data. Trigger on ICA, group exercise, substance_use, open question, prevalence, deaths, opioid, alcohol, trend over time, or "ask your own question".

Use this skill for ADS/ADS2 statistical power, sample size, Type I and Type II error, power.t.test, pwr.t.test, pwr.anova.test, pwr.chisq.test, simulation-based power, or justifying whether to increase sample size. Trigger on power, sample size, beta, Type II error, underpowered, 0.8 power, pwr, or "what should we do next" when sample size is involved.

Use this skill for ADS/ADS2 conditional probability, Bayes theorem, Bayes factors, prior/posterior reasoning, logic-card implication tasks, probability trees, lie-detector/base-rate problems, turtle/beach problems, and Markov-chain simulation. Trigger on Bayes, posterior, prior, conditional probability, Bayes factor, Markov chain, probability tree, lie detector, turtle, or card hypothesis.

Use this skill for ADS/ADS2 result wording, p-value interpretation, confidence interval interpretation, slope and coefficient interpretation, ANOVA and chi-square conclusions, Bayes posterior wording, power-analysis reporting, limitations, and "what should we conclude" exam prose. Trigger on interpret, conclusion, p-value, confidence interval, slope, R-squared, report wording, limitation, next step, or "how to write this result".

Use this skill for ADS/ADS2 bootstrapping, simulation-based tests, bootstrap confidence intervals, randomization/permutation tests, sample-with-replacement, simulation-based p-values, simulation power, and resampling medians or proportions. Trigger on bootstrap, simulation, sample with replacement, randomization, permutation, confidence interval by simulation, or "data do not fit assumptions".

Use this skill for ADS/ADS2 one-sample t-tests, independent t-tests, paired t-tests, Shapiro normality checks, Wilcoxon rank-sum/Mann-Whitney tests, Wilcoxon signed-rank tests, Kruskal-Wallis tests, and choosing between parametric and non-parametric group comparisons. Trigger on t-test, paired test, before after, normality, Shapiro, Wilcoxon, Mann-Whitney, rank-sum, signed-rank, Kruskal, or non-parametric.
