How to I sort out various unstandardised data from a single cell ?
For context, I'm trying to find out which marketing medium is the most effective to be used by Starbucks.
Attached is the dataset used and the column pertaining to my part is question 19.
As you can see, the data are retrieved from survey forms, as such, the format of their answer varies (e.g. some people only choose 'social media' as how they hear about promotions whereas some chose multiple methods (e.g. Starbucks Website/Apps;Social Media;Through friends and word of mouth). So my question is, is there anyway that i can sort out those with multiple answers so i can accurately count which is the most favourable medium to be used?
Thank you !
