As per PLOS ONE data sharing policies, you need to share all your data publicly. From the email, it seems that you have just shared the results of the statistical derivations, such as the mean, median, etc. However, you will need to share all the underlying data. To explain this more clearly, you need to provide all the individual data points from which you derived the mean or median. You can provide the entire dataset as supporting information which you can probably upload on the submission page or send to the editor via email.
However, if the dataset is too large to upload as supporting information, you will have to create an account in a public data repository such as arXiv, figshare, Dryad, etc. and put up your data there. Once you upload your dataset on the repository, you should give the editor access to the data. Usually, most public repositories are associated with a DOI. In that case, you have to give the DOI to the editor. If the repository is not associated with a DOI, it will give you an accession number, which you should share with the editor.
