Descriptive research using a ____ design tracks the responses of the same sample of respondents over time.
Andreyy89

Descriptive research using a  <u>longitudinal</u> design tracks the responses of the same sample of respondents over time.

The correct option is C.

<h3>What is  longitudinal design?</h3>

A longitudinal study is a type of research design where the same variables are repeatedly observed over a set amount of time, whether it be short or long. Even while it can also be set up as a longterm randomized experiment, it is frequently a sort of observational study.

<h3>What type of design is longitudinal?</h3>

There are two different types of study designs: longitudinal studies and cross-sectional studies. Data are gathered from a population in a cross-sectional study at a particular time; in a longitudinal study, data are gathered over an extended period of time from the same sample.

<h3>What is Descriptive research?</h3>

The characteristics of a population or phenomenon under study are described via descriptive research. It doesn't explain how, when, or why the qualities developed. It answers the "what" question instead.
