The hypothesis is a claim the researcher makes to predict what is expected to occur. In this prediction, the researcher states a relationship between the dependent and independent variables.
A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact.
The researcher hypothesizes in order to predict what is going on or what is expected to occur. The hypothesis must express what is expected to occur in a perfectly comprehensive manner.
The hypothesis is a claim of how it works a relationship between two or more variables. The exposed relationship must be logical and clear.
The hypothesis must be objective. There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.
Here, we need to propose a hypothesis using the provided independent and dependent variables, IV and DV respectively.
Let us remember that the IV is the one that causes an efect on the DV. Any change in the IV will cause a change in the DV, which might be directly or inversely proportional.
6.
IV-different temperatures of water
DV - the breathing rate of goldfish
Hypothesis: If Goldfishes are exposed to different water temperature, their breathing rate will change.
7.
IV-amount of water
DV - rate of photosynthesis
Hypothesis: If plants are grown with different amount of water, they will express different photosynthetic rates.
8.
IV- brand of running shoes
DV-running time in race
Hypothesis: If runners use a specific technical brand of running shoes, they will shorten the running time in a race.
