Data Validator
Check if your dataset conforms to the Metapsy data standard
Dataset Upload
On this page, you can upload a dataset to be forwarded to the Metapsy Data Validator. Datasets can either by clicking on the Upload button. Both comma-separated values (.csv) and Microsoft Excel (.xlsx) files can be uploaded. If you are uploading a .csv file, please make sure that the delimiter and decimal mark settings below conform with your dataset.
Alternatively, by clicking on Import "toy" dataset, you can import an example dataset into the app. This dataset is already correctly preformatted and is available for illustrative purposes.
General Information
This application allows to check if meta-analytic data sets conform with the
Metapsy data standard.
The analysis module
of the metapsyTools
package provides several functions that allow to run various meta-analytic
models conveniently using R; but this requires that the data has been correctly pre-formatted first.
This goal of this application is to mimic functionalities of the
preparation module
in metapsyTools
. Once all validation steps are completed successfully, users can
download a correctly formatted dataset with calculated effect sizes which can then by analyzed
"out of the box" in R using the analysis module of the package.
Submitted is only saved temporarily and deleted after the session is closed. Nontheless, make sure to never upload data that contains sensitive, personal or de-anonymized information!
Imported Dataset
Scroll down and click on Change columns to edit the data.
You can also change a single cell value by double-clicking on it.
Calculation of effect sizes will only be possible after all formatting issues are resolved.
No conflicts were detected during the effect size calculation. Please confirm that the effect sizes were calculated correctly below.
Dataset
The light blue columns below show the effect sizes calculated for each comparison. Please make sure to check if all the effect sizes have been calculated as intended. See the Metapsy documentation for more details (section "metapsyTools variables").
Download
In this tab, you can download the validated data set with calculated effect sizes. The data can be downloaded in three formats: as an R Data file, Microsoft Excel sheet, or as a .csv file. The default export setting is to download as an R Data (.rda) file. This format is recommended, it is easy to import in R, and less prone to import errors.
To import the .rda file, put it into you working directory and then click on within
the file explorer in R Studio. The dataset is then automatically imported into your R
environment under the name metapsy.data
.
Test Dataset
This section allows you to run a test meta-analysis based on the validated data set. In the table below, select rows that you want to have included in the meta-analysis by clicking on them. At least 5 rows need to be selected, and also make sure that the selected rows actually contain effect size data.
After clicking on Run Meta-Analysis, the selected data is fed forward to the
runMetaAnalysis
function, and the output of the function is displayed below. The version of metapsyTools
used by this App is . It is not guaranteed that analyses of the data will also
work if your local version of metapsyTools
differs substantially.
