A survey question asks to tick all options that are relevant to the users (Check all that apply). Respondents are given 6 options and they can tick as many as they want.
I want to determine which are the top 3 options.
I can sort the options by frequency (see data below), but that does not tell me whether e.g. the third most frequent option is significantly more frequent than the fourth.
I want to test whether the difference in frequency is statistically significant between the 6 options and compare the different options (post hoc).
My best option is to calculate the confidence interval around each frequency and compare those, but I wonder whether there is a more rigorous test.
This is the data (I sorted it by descending frequency)
sample size n=150
- Feature Frequency
- qualifications 82%
- work_experience 75%
- case studies 53%
- personal_brand 49%
- awards 42%
- career_goal 12%
