A hypothesis is a tentative statement that proposes a possible explanation to some phenomenon or event.

A useful hypothesis is a testable statement which may include a prediction.

Biology Lab Report Format

When Are Hypotheses Used? The key word is testable. That is, you will perform a test of how two variables might be related.

This is when you are doing a real experiment. You are testing variables. Usually, a hypothesis is based on some previous observation such as noticing that in November many trees undergo colour changes in their leaves and the average daily temperatures are dropping.

Are these two events connected? Any laboratory procedure you follow without a hypothesis is really not an experiment.

It is just an exercise or demonstration of what is already known. How Are Hypotheses Written? Salt in soil may affect plant growth. Plant growth may be affected by the color of the light.

Bacterial growth may be affected by temperature. Ultra violet light may cause skin cancer. Temperature may cause leaves to change color. However, their form is not particularly useful. Using the word may does not suggest how you would go about proving it.

If these statements had not been written carefully, they may not have even been hypotheses at all. One way to prevent making such easy mistakes is to formalize the form of the hypothesis.

If the incidence of skin cancer is related to exposure levels of ultraviolet lightthen people with a high exposure to uv light will have a higher frequency of skin cancer. If leaf color change is related to temperaturethen exposing plants to low temperatures will result in changes in leaf color.

Notice that these statements contain the wordsif and then. They are necessary in a formalized hypothesis. But not all if-then statements are hypotheses. In a formalized hypothesis, a tentative relationship is stated. For example, if the frequency of winning is related to frequency of buying lottery tickets.

If you always ask yourself that if one thing is related to another, then you should be able to test it. Formalized hypotheses contain two variables. In the statements above the dependent variable is underlined and the independent variable is underlined and italicized. The ultimate value of a formalized hypothesis is it forces us to think about what results we should look for in an experiment.
