An example of a qualitative observation would be,
there is fifteen lab tables in our class.

Mr. Yablonski tells 5 jokes every class.
Mr. Yablonski is awesome.
7
Replication of experiments is necessary because
2 trials are needed to state a conclusion.
scientists need extra copies of experiments for their data.
This is a trick question. It is unnecessary.
the more "like" results obtained, the more valid they are.
8
A hypothesis is
useless unless it is proven correct by analyzing the data.
a large, mostly herbivorous mammal.
an attempt to answer a question or problem.
always written "If the DV, then the IV."
9
Why do scientists construct models?
Because scientists like to build models.
To find the independent variable.
To study something too big, small or complex.
Because they can't afford the real thing.

Inferences are
forecasts.
attempts to explain something that you observed.
