| Data are often collected to test a hypothesis. A hypothesis could be a simple statement like this.
Fruit grows from flowers Suppose you perform an investigation to test this hypothesis. You examine flowers on an apple tree every two weeks. You make drawings to record your observations. The observations are your data. |

| If your data do not support your hypothesis check for errors in your experiment. If you do not find any errors, your hypothesis was incorrect. | |||||||||||

| At the end of your investigation, you study your data. You ask yourself, "Do the data support my hypothesis?" Your drawings show that an apple formed where a flower once bloomed. The data that you collected support your hypothesis.
If your drawings showed that apples do not grow from flowers, the data you collected would not support your hypothesis. This result might lead you to perform another investigation to find out where apples come from. |
