Notes:
Note:This data is for demonstration purposes only. There were actually 643 members of the #AgChat Facebook group as of this date, but the ‘members to .csv’ ap limits data retrieval to 499 observations, so this represents only a sampling of actual members. Observations are also omitted for missing values for variables in each respective analysis.For instance, only 24 observations of the available 499 had hometown data listed.
