I would like to use SE formula {SE=Sqrt(p*(1-p)/n)} to calculate SE for multiple response questions. For instance, for the question "what social media platform do you use? select all that apply" from 20 people, I got the these responses: Facebook 19/20 Twitter 17/20 Instagram 14/20 Whatsap 16/20 Tiktok 10/20 Tumblr 3/20 Other 7/20
Is the above formula ok to use? Thanks
