Final answer:
The abbreviations D?H?Q? do not match the provided options and thus cannot be accurately defined without additional context. For the survey data, the number of times per week is quantitative discrete data, the duration is quantitative continuous data, and the colors of the houses are qualitative data.
Step-by-step explanation:
The abbreviations D?H?Q? corresponds to none of the options provided. In statistical terms, these could potentially stand for Data, Hypothesis, and Quantity but this is a guess and the actual meaning must be provided for an accurate answer.
Quantitative data can be subdivided into discrete and continuous data. Qualitative data, also known as categorical data, describes attributes or characteristics that cannot be measured with numbers.
The number of times per week is quantitative discrete data because it can be counted and has a finite number of values. The sampling method used in the study is systematic sampling because residents are selected at regular intervals (every eighth house). For the data collected in the study, duration or amount of time is an example of quantitative continuous data because it can take on any value within an interval and is not restricted to individual counts. The colors of the houses are qualitative data because they describe characteristics which cannot be quantified.
