Buzzy$$s has recently opened its $12$th store in the Dallas$-$Fort Worth area. Currently, the chain offers tacos, fajitas, and burritos. Management is considering offering a super taco that would be two times as large as their regular taco and would contain $6$ ounces of ground beef or shredded chicken. The basic taco has $3$ ounces of spiced ground beef or shredded chicken, lettuce, and cheese. Management feels that the super taco should offer more options.

A marketing research study was undertaken to determine what those other options should be$.$ A key question on the survey was, $$What$,$ if anything, would you like to see added to our basic taco besides the beef or chicken?$$ The question is open$-$ended, and the coding categories that have been established for the question are shown in the table.

Questions

How would you code the following responses?

I usually add a green, avocado$-$tasting hot sauce.

I cut up a mixture of lettuce and spinach.

I$$m a vegetarian; I don$$t use meat at all. My taco is filled only with guacamole.

Every now and then I use a little lettuce, but normally I like cilantro.

Is there anything wrong with having a great number of responses in the $$other$$ category? What problem does this present for the researcher?
