Final answer:
Quantitative data in the given study pertains to measurable changes in population, business, and technology trends over the last century, such as demographic statistics, market shares, and technological adoption rates.
Step-by-step explanation:
In the given study, the quantitative data can be identified in information that represents numerical or measurable variations in population trends over the last century, such as population size, growth rate, or demographic components like age distribution and birth/death rates. In business trends and technology trends, quantitative data would involve statistical measurements like market share, sales figures, rates of technological adoption, and numbers related to innovation or patents filed. Unlike clothing trends, which are typically qualitative and focused on styles and preferences, quantitative aspects could include sales statistics or production numbers, albeit these are less commonly the study's main focus.
Quantitative data are essential in statistical methods, including surveys with large numbers of participants, census data analysis, or social network analysis. These methods yield data that can be quantified such as frequencies, averages, and percentages, providing a basis for comparisons and trend analysis. Understanding and interpreting these numerical facts aids in making informed conclusions about societal preferences and predicting future trends.
