Title: Data Sets for Psychometric Modeling
Description: Collection of data sets from various assessments that can be used to evaluate psychometric models. These data sets have been analyzed in the following papers that introduced new methodology as part of the application section: Yinghan Chen et al. (2021) <doi:10.1007/s11336-021-09750-9>, Yinyin Chen et al. (2020) <doi:10.1007/s11336-019-09693-2>, Culpepper, S. A. (2019a) <doi:10.1007/s11336-019-09683-4>, Culpepper, S. A. (2019b) <doi:10.1007/s11336-018-9643-8>, Culpepper, S. A., & Chen, Y. (2019) <doi:10.3102/1076998618791306>, Culpepper, S. A., & Balamuta, J. J. (2017) <doi:10.1007/s11336-015-9484-7>, and Culpepper, S. A. (2015) <doi:10.3102/1076998615595403>.

Experimental Matrix Reasoning Test Item Responses

Usage

items_matrix_reasoning

Format

An object of class matrix (inherits from array) with 400 rows and 25 columns.

Details

Items included:

Answer coding

The subjects answered a set of assessment items seeking to determine their matrix reasoning abilities. Subjects that answered with a value between 0 to 7 were marked as incorrect. Subjects who answered a question with 10 selected the correct answer and, thus, were marked as correct.

Notes

From the OpenPsychometrics' code book that accompanied the data, they noted:

  1. The possible answers were presented in two rows of four with a random order for each participant.

  2. The collection of this data was of mediocre quality.

Data pre-processing

We have applied list-wise deletion during pre-processing to remove any observations with missing values from the data set.

Answer coding

The subjects answered a set of assessment items seeking to determine the level of anxiety. Answers given in bold represent the desired response. If a subject matched this response, they were given a 1 inside of the item matrix, otherwise they received a zero.

Subset of Early Childhood Longitudinal Study, Kindergarten (ECLS-K)'s Approaches to Learning Item Responses

Description

Subset of Early Childhood Longitudinal Study, Kindergarten (ECLS-K)'s Approaches to Learning Item Responses

Usage

items_ordered_eclsk_atl

Format

An object of class matrix (inherits from array) with 13354 rows and 12 columns.

Details

Items were split between being answered by Parents and Teachers.

Data pre-processing

The Early Childhood Longitudinal Study, Kindergarten (ECLS-K) has been subset down both the number of observations and variables. In particular, only observations without any missing values from a set of reduced variables – given above – are included. If additional data is required, please visit the data download page found in the reference section.

Answer coding

Parents and teachers each answered a set of survey items involving a likert scale that ranged from "1 = never" to "4 = very often" regarding the subject. Within the teacher responses, they also had the option of marking "-7 = no opportunity to observe" option, which was treated as a missing observation. To align with C++, we perform a index shift backward of 1 and, thus, make the scale "0=never" to "3=very often".
