1. Observations and Inferences

2. Observations & Inferences
We are constantly making observations and inferences. We do this both consciously and unconsciously.
We are constantly making observations of the world around us.

3. Observations & Inferences
The act, practice, or power of noticing.
We use our senses (sight, taste, touch, smell, and hearing) to make our observations.

4. Observations & Inferences
There are two main types of observations:
Quantitative observations
An observation in the form of a quantity.
ex: The desk is 1 meter tall.
Qualitative observations
A quality or characteristic of a given object or event.
ex: The sky is blue.
Our brains are constantly trying to make sense of our observations.

5. Observations & Inferences
The act of making conclusions or making sense of your observations.
Our brains are constantly making inferences about the world around us.
