Final answer:
To determine if a hypothesis is completely supported, you compare the expected and actual observations. If they match, the hypothesis is supported. If there are differences, the hypothesis is refuted.
Step-by-step explanation:
In order to determine if the hypothesis was completely supported, you need to compare the expected observations with the actual observations. If the actual observations match the expected observations, then the hypothesis is supported. If there are any differences between the actual and expected observations, then the hypothesis is refuted.
For example, if the hypothesis predicts that adding fertilizer to plants will increase their growth, you would need to conduct an experiment where one group of plants receives fertilizer and another group does not. If the plants with fertilizer grow taller than the plants without fertilizer, then the hypothesis is supported. If there is no difference in growth between the two groups, then the hypothesis is refuted.
