Observation vs. Inference

Observations An observation is any information that we gather using our five senses. EXAMPLE:

OBSERVATION VS. INFERENCE. OBSERVATION USE YOUR SENSES TO GATHER INFORMATION USE YOUR SENSES TO GATHER INFORMATION FACTS ONLY FACTS ONLY QUALITATIVE OR.

Qualitative Observation A qualitative observation uses your 5 senses and includes descriptions of sights, sounds, smells, and textures.

Observing & Inferring. Observation: using the 5 senses to gather information (see, touch, smell, hear or taste) Inference: Making an interpretation based.

Observations & Inferences

Observation Using the five senses to gather information (data)

Data Information gathered through observation

Types of Data Quantitative – observations that are measured or counted Ex: 28 students, three meters long, 10 seconds Qualitative – observations that are not easily measured Ex: colors, rankings, descriptive

Examples Usain Bolt ran the 100 meters in a world record time of 9.69 seconds. Usain Bolt ran faster than anyone in the world.

Quantitative or Qualitative? There are too many students in my last class.

Quantitative or Qualitative? Justin Bieber is a great singer.

Quantitative or Qualitative? Roger Maris hit 61 home runs in 1961.

Quantitative or Qualitative? There are nine green cars in the parking lot

Inference A logical conclusion based on observations and your prior knowledge Allow you to make sense of what you observe
