The video tutorial explains the difference between observations and inferences. Observations are factual statements gathered through the senses, while inferences are explanations based on observations and prior knowledge. The video provides examples of both concepts and encourages viewers to practice distinguishing between them.

What is the main difference between an observation and an inference?

• Observation is based on prior knowledge, while inference is based on senses.

• Observation is a factual statement using senses, while inference is an explanation based on observations.

• Observation involves experimentation, while inference does not.

• Observation is always correct, while inference is always incorrect.

Which of the following is an example of an observation?

• The lion is planning to ambush its prey.

• The lion is big.

• The lion is the king of the jungle.

• The lion will hunt soon.

Which sense is used in the observation: 'The stone is smooth'?

• Touch

• Sight

• Taste

• Smell

What is the role of prior knowledge in making an inference?

• It replaces the need for observations.

• It is only used in scientific experiments.

• It helps in forming explanations based on observations.

• It is not used at all.

Which of the following is an inference?

• The clouds are dark.

• It will rain soon.

• The music box plays a loud sound.

• The room smells nice.
