Question

1. what is the next step if the data from an investigation do not support the original hypothesis?

the hypothesis is revised to explain the data from the experiment.
the data are adjusted to match the observations.
the data are incorrect and the experiment is run again.
the data are revised to support the hypothesis.

Explanation:

In the scientific method, if data does not support the original hypothesis, the next step is to revise the hypothesis to explain the data. Data should not be adjusted to match observations (unethical in science), nor should incorrect data be used to rerun an experiment. Revising the hypothesis to fit the data is the proper scientific approach.

Answer:

The hypothesis is revised to explain the data from the experiment.
