  4. 4. Terms To Know<br />Sample – set of things about which you collect data.<br />Data Set – the information you collect.<br />Sample Size – the size of the data set.<br />
  5. 5. When Do People Collect Data?<br />When people choose a sample to collect data, it is because there is some sort of uncertainty about the data.<br />If you are sure of the data, then there is no need to collect them. <br />Example:<br />You would not ask students whether they have a nose or whether they woke up this morning.<br />But you might collect data on what color their eyes are or how much they slept last night.<br />
  6. 6. Choosing A Data Representation<br />The type of data you have determines the possible ways to display them. <br />When you ask people what color their eyes are, the answers are separated into categories.<br />Data that can be sorted in this way are called categorical data.<br />If the sample size is small, you can list all the data.<br />If the sample size is large, data should be summarized and displayed.<br />
