The Earth revolves around the Sun. Is this an observation or an inference.
Observation (we literally observe this)

Is this an example of precision or accuracy?
Precision

Meter (m)
Identify this trend
x->1,2,3,4,5
y->2,4,6,8,10
Linear
A student sees a plant leaning towards the window and says, "The plant is growing toward the sunlight." What part is the observation and which part is the inference?
Leaning towards the window= Observation
Growing towards the sunlight= Inference
A student measures a table that is 100 cm.
He gets measurements of 100.1cm, 100.2cm, and 100.1cm.
Are the measurements accurate, precise, or both?
Both
Accuracy=close to the correct answer
Precision=Answers are close to each other

2)There is broken glass all around him below a window.
3) You see a person standing above him 2 floors up in the window.
Answers may vary but it can be assumed that the man was pushed out the window.
