# Data Entry Overview [Adding a Trait](https://www.betydb.org/traits/new) \label{sec:traits}  Before entering data, it is first necessary to add and select the  citation that is the source of the data. It is also necessary for each  data point to be associated with a Site, Treatment, and Species.  Cultivar information is also required when available, but it is only  relevant for domesticated species. Fields with an asterisk (*) are  required.   ## Adding a Trait \label{sec:traits}  [Form used to enter a new trait](https://www.betydb.org/traits/new)  In general, a 'trait' is a phenotype (a characteristic that the plant  exhibits). The traits that we are primarily interested in collecting  data for are listed in Table \ref{tab:traits}. Before adding trait data, it is necessary to have the citation, treatments, and site information already entered. If the correct

chambers, pots, or individual plants. Sometimes this value is not  clearly stated.   ### ##  dateLOC The date level of confidence (DateLOC, Table \ref{tab:dateloc}) provides an indication of how accurately the date associated with the trait or yield observation is known.   It provides the values that should be entered in this field.   If the event occurred at a level of precision not defined by an integer in this table, then use fractions. For example, we commonly use 5.5 to indicate a one week level of precision.   If the exact year is not known, but the time of year is, then use 91 to 97, with the second digit to indicate the information known within the year.  #### ##  Statistics Our goal is to record statistics that can be used to estimate standard  deviation or standard error (https://www.authorea.com/users/5574/articles/6811/).
