1. Which of the following best describes a quantitative observation?
The solution turned blue.
The plant grew 5 cm in a week.
The smell was pungent.
The texture was rough.
2. Observer bias occurs when:
The experimental design is flawed.
The observer's expectations influence the data collected.
The sample size is too small.
The measuring instruments are inaccurate.
1. Scientific observations can be broadly categorized into observations, which describe qualities, and observations, which involve numerical measurements.
2. When conducting an experiment, it is crucial to record observations and to ensure data integrity.
1. Explain the difference between an observation and an inference, providing an example for each.
2. Describe two methods scientists use to minimize bias during the observation process.
1. A hypothesis is a type of observation.
True
False
2. Using a microscope to view cells is an example of extending human observation with tools.
