On this Picostat.com statistics page, you will find information about the sat.act data set which pertains to 3 Measures of ability: SATV, SATQ, ACT. The sat.act data set is found in the psych R package. You can load the sat.act data set in R by issuing the following command at the console data("sat.act"). This will load the data into a variable called sat.act. If R says the sat.act data set is not found, you can try installing the package by issuing this command install.packages("psych") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the sat.act R data set. The size of this file is about 12,633 bytes.

Documentation

3 Measures of ability: SATV, SATQ, ACT

Description

Self reported scores on the SAT Verbal, SAT Quantitative and ACT were collected as part of the Synthetic Aperture Personality Assessment (SAPA) web based personality assessment project. Age, gender, and education are also reported. The data from 700 subjects are included here as a demonstration set for correlation and analysis.

Usage

data(sat.act)

Format

A data frame with 700 observations on the following 6 variables.

gender

males = 1, females = 2

education

self reported education 1 = high school ... 5 = graduate work

age

age

ACT

ACT composite scores may range from 1 - 36. National norms have a mean of 20.

SATV

SAT Verbal scores may range from 200 - 800.

SATQ

SAT Quantitative scores may range from 200 - 800

Details

hese items were collected as part of the SAPA project (http://sapa-project.org)to develop online measures of ability (Revelle, Wilt and Rosenthal, 2009). The score means are higher than national norms suggesting both self selection for people taking on line personality and ability tests and a self reporting bias in scores.
