Instead of using pivot tables, we can use the Advanced Filter option to find unique values from a series of data and then use the COUNTIF function to count the frequency of each category. This data can be collected through qualitative methods and research such as interviews, survey questions, observations, focus groups, or diary accounts. 8 /Filter /FlateDecode >> This is a numerical value with a meaningful order of magnitudes and equal intervals.
