Presentation on theme: "A test of your observation skills…"— Presentation transcript:
1A test of your observation skills… Observations vs. InferencesA test of your observation skills…Contributions by D. Padilla, D. Johnson, & E. MarconiFor more optical illusions go to:
2Observations Use one or more of the 5 senses to gather information A noting and recording of…. FACTS!!!Example: There is one TV in the room.
3ObservationsObservations: We use our senses to gather information about the world around us. There are two types of observations.
4QualitativeQualitative observation: (quality) Usually made with our senses.Color, shape, feel, taste, sound.Examples:Olivia is wearing a blue sweater.The lab tabletop is smooth.The dog’s fur is shiny.
5QuantitativeQuantitative observation: (quantity) How many. Will always have a number.Based on exact measurement.Examples:The room is 8 meters across.Sarah is 141-cm tall.Sam weighs 450 Newtons.
6InferencesLogical interpretation based upon prior knowledge and experienceBased upon observationsExample: When you entered the room, you most likely inferred that the individual in the front of the room is the teacher.
7Making InferencesYou are at the counter in the office to get a bus pass signed. You see a student leave the principal’s office crying and upset. We could make an inference as to why the student is upset.Could be in trouble (ISS, OSS, expelled)Family problems at home (sick, accident)Student not feeling wellStudent has poor grades (failing, retention)
8Note the DifferencesIn laboratory exercises, record observations NOT inferencesInferences may be used when writing the conclusion in your lab report.Let’s test your observation skills…
