Misleading <ul><li>When a government official or a secretary have to present data, they want to show their boss only data that is good. </li></ul><ul><li>But sometimes, when that data is basically useless, or even worse, bad, the presenter needs to modify how they present the data. </li></ul><ul><li>The next few slides show examples of how misleading just a few modifications to the presentation method can be. </li></ul>
