What type of data is described as observations made or measured using numbers?

Quantitative data refers to observations that can be measured and expressed numerically, allowing for statistical analysis. This type of data includes counts, measurements, and other forms of numerical representation that provide a precise and objective way to present information.

In contrast, qualitative data is more descriptive, focusing on characteristics and qualities that cannot be easily quantified with numbers, such as colors, textures, or subjective assessments. Additionally, primary data is information gathered firsthand for a specific research purpose, and secondary data is information collected from existing sources for a different purpose than the current study. Both primary and secondary data can contain qualitative and quantitative elements, but the key aspect of quantitative data is its numerical nature, which facilitates mathematical computation and comparison among groups or variables. Thus, the identification of quantitative data as observations made or measured using numbers is accurate and foundational in many fields, including veterinary science.
