Which is an example of making a quantitative observation?

Quantitative observation is a data collection method that belongs to quantitative research, and refers to observation that uses precise and computational methods, often statistical in human sciences. The term is commonly used in the human sciences, such as social sciences and education, but broadly it can also refer to natural sciences.

For example, sociology focuses on human-made communities and phenomena resulting from the activities of human communities. In quantitative observation, the researcher seeks to collect empirical evidence for himself. By looking at the evidence, the researcher seeks to understand a social phenomenon. By examining the observational data, the researcher seeks to generalize the observational data he has collected through a quantitative (numerical) hypothesis.

A clear example of quantitative observation occurs when the researcher records the number of people who possess a certain characteristic in a massive event (for example, the number of white people in a Republican rally).

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
