Answer:
More experimental.
Step-by-step explanation:
A hypothesis is formulated on the basis of some observed, but unexplained behavior. It is usually preceded by an exclamation from the researcher of "What the heck? Did you see that? It went up and turned blue, when it should have gone sideways and turned red."
The observed behavior was unexpected, so the researcher wants to know why. The first place to start is with an hypothesis: an explanation of what might be happening. It must be a "testable" hypothesis - an explanation that provides an avenue for testing whether the hypothesis may contain some truth. E.g., the lab tech created sufficient momentum in the sample to make it react when he/she moved it from the table to the cabinet.
This can be tested. Just do the same experiment but control movement of the sample. If the reaction does NOT occur under the new conditions, then one might advace the observation as a theory. Ni=ot proven, but the data are consistent with the hypothesis. A theory is based on some level of experimental results, to move it up from an hypothesis.
