**Study files, codebooks, scripts**
This component contains scripts/codebooks and [Qualtrics][1] files for all versions of the Many Labs 2 script.
An overview of the variables used in the primary analysis for each study may be found in [ML2 Codebook for Primary Analyses][2]. This is a useful companion to the dataset.
The detailed codebook for each slate can be found here:
1. [ML2 Slate 1 Codebook.docx][3]
2. [ML2 Slate 2 Codebook.docx][4]
These files are annotated Word-output of the Qualtrics script. They contain the exact wording of each item, and the numeric coding for each response.
Users who want to import the full survey into Qualtrics can use these two .qsf files:
1. [ML2 Slate 1 Qualtrics File.qsf][5]
2. [ML2 Slate 2 Qualtrics File.qsf][6]
The .qsf files can be imported into Qualtrics (even a free/trial account) and recreate the study exactly. As of 8/16/17, follow [this guide][7].
You may also "take" the study as if you were a participant, with studies in randomized order, by using these Qualtrics links:
1. [Take Slate 1, default US-English version][8]
2. [Take Slate 2, default US-English version][9]
The above files are from the "default" version of the script, used for most US, English-speaking labs. In many cases, site or country-specific changes were made to the study script for individual sites (e.g., translations, site-specific modifications, etc.). In these cases, the US script was duplicated and then modified as a separate study file, thus creating many different Qualtrics versions of the Many Labs script (with consistent variable naming, etc.).
Study codebooks and study files for all of these specific study versions can be found in the .zip files:
1. [Detailed Codebooks (Word Output).zip][10]
2. [Qualtrics (.qsf) Files.zip][11]
These individual scripts can be linked back to which lab used them by the 'filename' column in the datasets along with the 'site identifier' or 'source' columns.

Extra Notes:
- Font format and style is omitted from the Word output versions, as well as some images (although all images are added back in to the two main codebooks). For an exact representation of what participants saw, please import the .qsf file(s) into Qualtrics.
- In the Word output, the text at the start of a line is the name of the variable in the dataset. For example, most versions start with either "consent" or "ml2.int".
- For most items, numbers in parentheses next to a response option in the Word output represent how that response is coded numerically in the dataset. For open-text-responses and Matrix-style questions, the number next to the item represents the "question export tag", which simply indicates how the variable itself is named in the dataset. In some cases we have renamed those variables in the
dataset to be consistent across sites, but those changes are not
reflected in these Word outputs (the Qualtrics itself is updated, but
according to Qualtrics support the Word output does not update to
those specific changes). Variables that may show this include: Slate 1: *and1.3, and1.4, and2.3, and2.4, van.p1.2, tipi*;
Slate 2: *zhon.dv.1, geis.dv, tipi*
