Dataset for "The 19-Item Environmental Knowledge Test (EKT-19): A Short, Psychometrically Robust Measure of Environmental Knowledge"

This dataset consists of two files – one main dataset, and one dataset for the re-test analysis. The main dataset includes an anonymous participant ID, binary responses to 30 environmental knowledge questions, participant's sex, age and duration to complete the task. The re-test dataset includes all the same variables, completed for both the initial study and at re-test after nine weeks. When collecting this dataset, we were seeking to develop a new measure of environmental knowledge, building upon an existing measure by Geiger et al. (2019).

Documentation

Data collection method:

A UK sample of 346 undergraduate students completed the study via the University’s research participation scheme, 121 of whom repeated the study nine weeks later for test-retest analyses.

Additional information:

The data is mostly binary (0,1) denoting (incorrect, correct) answers to the environmental knowledge questions. In the sex variable, 1 denotes male, and 0 female. Age is in years. Duration_EKT30 variable denotes how long the full 30 items of the environmental knowledge measure took each participant, measured in seconds (s).
