This article explores the fundamental concepts of observation versus inference, as well as accuracy versus precision in scientific contexts. Observations involve using our senses to gather factual information, while inferences are logical conclusions drawn from those observations. Inaccuracy and precision are defined within chemistry, highlighting the importance of measuring closeness to actual values and consistency across measurements. Additionally, the distinction between qualitative and quantitative data is explained, emphasizing their roles in scientific analysis and evaluation.
E N D
Observation • Using your 5 senses to note facts about something • The car is grey • The cat is grey • The car has at leasttwo hubcaps
Inference • A logical guess or conclusion based on observations • The car has 4 hubcaps • The car is parked in a garage • The cat is holding up the car
Accuracy versus precision(in chemistry) Accuracy: how close your measurements are to the actual amount Precise: how close your measurements are to each otherunder the sameconditions
Qualitative versus quantitative • Qualitative: • Quality • Describing something without using specific numbers or measurements • Color, category, emotion, condition • Quantitative: • Quantity • Measuring or using specific numbers to compare • Speed, size, amount, cost
Quantitative Vs. Qualitative Vs.
