Answer: this is qualitative and categorical (binary) data

Step-by-step explanation:

There are no measurements. The observation is qualitative: observation of some change in appearance. It is categorical in that the possible values are only ‘no sheen’ or ’sheen’.

Answer: Qualitative data

Step-by-step explanation:

Since we are informed that the scientist writes down that there was an iridescent sheen on the surface of the water, this is a qualitative data.

Qualitative data is a firm of data that one can observe and then record. It should also be noted that it is non numerical. It can be gotten from observations, conducting focus groups, having a one-to-one interviews, etc.
