In descriptive observation one do not wish to modify the activity, he want it to get registered such as it would take place without his presence. In this observations are detailed and focused, in which questions about a phenomenon are carefully  examined and expressed at the outset that is why it is considered quantative as well as qualitative.

A descriptive observation may very well be a mixture of both quantitative and qualitative as it can utilize elements of both types. Qualitative deals with the kinds of observations that cannot be measured in numerical form. Quantitative data is just that.
