Question 91

An environmental scientist investigating the microclimatic effects of urban green spaces performs two tasks:

She installs 12 digital thermometers across a municipal park to log ambient temperature at 10-minute intervals for three weeks ( $D_1$ ).
She retrieves a public database of historical daily solar radiation values compiled by a regional airport weather station over the last 40 years ( $D_2$ ).

Which of the following correctly classifies the datasets $D_1\,$ and $D_2$ , and identifies a valid disadvantage of utilizing $D_2\,$ compared to $D_1\,$ for her specific investigation?

$D_1$ is secondary data, $D_2$ is primary data. A disadvantage of $D_2$ is that it is highly prone to researcher bias during the data collection stage.

$D_1$ is primary data, $D_2$ is secondary data. A disadvantage of $D_2$ is that it is inherently qualitative and cannot be used in quantitative statistical modeling.

$D_1$ is primary data, $D_2$ is secondary data. A disadvantage of $D_2$ is that it may lack the precise spatial relevance or measurement resolution required for the park-specific study.

$D_1$ is secondary data, $D_2$ is secondary data. A disadvantage of $D_2$ is that retrieving archived historical records is significantly more time-consuming than deploying field equipment.
