How do observations relate to hypotheses? check all that apply. observations leading to a hypothesis come from prior knowledge or research. observations leading to a hypothesis come from the same experiment. a hypothesis is formed based on observations from many experiments. a hypothesis is formed after making observations but before performing an experiment.

The correct answer is A hypothesis is formed after making observations but before performing an experiment.

Observation refers to a careful study of phenomena with the intention of deriving a logical explanation for such phenomena.

In scientific study, research begins with an observation. The observation of a given phenomenon leads the research to draw up a plausible explanation for the observation called a hypothesis.

This hypothesis becomes the guide for experimentation. The experiments are expected to confirm or disprove the hypothesis.

Hence, a hypothesis is formed after making observations but before performing an experiment.

A hypothesis is formed after making observations but before performing an experiment.

Observation is a statement that is based on something noticed or observed. First we observe something and then make hypothesis. Hypothesis is a statement that can be true or false after performing an experiment. Hypothesis can be made on the basis of observations and at that time no experiment was performed so we can conclude that hypothesis is made from observation before performing an experiment.
