Abiologist who is measuring the length of salmon as they travel upstream is collecting qualitative data. true or false ?

False

Explanation:

Qualitative data is one which can be observed with our senses such as sight, smell, touch, taste, and hearing. Qualitative observations do not involve any measurement. Example: Colour of an object

Quantitative data is one which involves measurement of data in numbers. Example: speed of an object

As the biologist is measuring the length of salmon as they travel upstream , it measures data in numbers and hence is a quantitative data and not a qualitative data.
