title: First-year proficiency on binomial/normal distributions: coded exam responses (ODL university, N=120)

description: Research hypothesis
(H1) Students’ conceptual framing of a probability-distribution task (Conceptual Understanding, CU) is positively associated with procedural success (Applying Statistical Methods, ASM) within the same response; (H2) Primary error types are concept-specific across binomial exact-probability, normal between-probability, and inverse-normal (percentile→cutoff) items.

What the data are
A de-identified, item-level dataset created from 120 invigilated exam scripts in an open-distance learning (ODL) statistics module. Only three sub-questions were coded (one per concept): Binomial (exact), Normal (between), Inverse-Normal (percentile→cutoff). Each response is scored on CU and ASM (0–3), flagged Attempt (Y/N), and assigned a mutually exclusive primary error: MODEL/PARAM, EVENT, Z/QUANT, COMPUTE/TABLE, BACK-TRANSFORM, or NOERROR. Non-attempts are recorded separately.

How the data were gathered
Scripts were written under exam conditions (no software; tables + non-programmable calculators). After consent and de-identification, responses were double-coded on a calibration set; Cohen’s κ=0.83. The researcher then applied the finalized rubric to all 120 scripts. Ethics approval: CREC Ref 003/EGM/2014.

Files & structure (key variables)

Coding.xlsx (one row per ScriptID × item). Fields: ScriptID (pseudonymous), Item (Binomial/Normal/InverseNormal), Attempt (Y/N), CU (0–3), ASM (0–3), PrimaryError (MODEL|EVENT|Z/QUANT|COMPUTE/TABLE|BACK|NOERROR). Optional admin columns may include Notes or brief anonymised excerpts.

Codebook.pdf (or .docx): variable definitions, scoring anchors, examples.

Rubric.pdf (CU/ASM level descriptors).

What the data show (headline results to orient users)

Non-attempt: 16% (binomial; 19/120), 20% (normal; 24/120), 49% (inverse-normal; 59/120).

Means on attempted: CU—1.60 (bin), 2.29 (norm), 1.05 (inv); ASM—0.88 (bin), 1.67 (norm), 0.20 (inv).

CU–ASM correlations (attempted): r≈0.80, 0.73, 0.78 (bin, norm, inv).

Dominant errors: Binomial—MODEL/PARAM (46/101); Normal—COMPUTE/TABLE (21/96) and Z/QUANT (9/96); Inverse-Normal—EVENT (24/61) and Z/QUANT (24/61).

How to interpret/use

Unit of analysis is the item response, not the student. Compute CU/ASM summaries on attempted responses only; report non-attempts separately for transparency.

PrimaryError is mutually exclusive and reflects the issue most proximal to an incorrect result (tie-breaker rule).

Appropriate uses: learning analytics; error-profiling; assessment design; replication of CU↔ASM association; building targeted teaching interventions (e.g., binomial model-checks; normal table-literacy; inverse-normal percentile→event→z→x routine).

Limitations
Single institution, three items, manual/table context; interpretations should not be generalized to software-based assessments without caution.

title: Replication Data for: A serial founder effect model of phonemic diversity based on phonemic loss in low-density populations

description: It has been observed that the number of phonemes in languages in use today tends to decrease with increasing distance from Africa. A previous formal model has recently reproduced the observed cline, but under two strong assumptions. Here we tackle the question of whether an alternative explanation for the worldwide phonemic cline is possible, by using alternative assumptions. The answer is affirmative. We show this by formalizing a proposal, following Atkinson, that this pattern may be due to a repeated bottleneck effect and phonemic loss. In our simulations, low-density populations lose phonemes during the Out-of-Africa dispersal of modern humans. Our results reproduce the observed global cline for the number of phonemes. In addition, we also detect a cline of phonemic diversity and reproduce it using our simulation model. We suggest how future work could determine whether the previous model or the new one (or even a combination of them) is valid. Simulations also show that the clines can still be present even 300 kyr after the Out-of-Africa dispersal, which is contrary to some previous claims which were not supported by numerical simulations​
description: The zip file contains the following documents and files:
- S1 Text: Supplementary results in DOCX, with different graphic simulations that complement the results mentioned in the published article. Graphics have been calculated from the data collected in the "Language database"
- S1 Database in XLSX. It is the Language database that contains the list of phonemes for 359 languages. For each language are provided the number of phonemes and the distance from the origin of the out-of-Africa. For these 359 languages, 908 different phonemes have been found. First, all languages ​​in the dataset were coded in strings of "1" and "0". This leads to a "full" matrix of 359 rows (languages) x 908 columns (phonemes). The presence of a phoneme is marked with a "1" in the corresponding position. The absence of a given phoneme is marked with a "0". Data from this database are used to generate the observed phonetic cline and the simulated phonemic cline, explained in the published article.
