Emmanuel And Thomas

  1. 1. Misleading Statistics The art of making small things big and big things small
  2. 2. 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>
  3. 3. Scales of Graphs <ul><li>The scale on this graph starts at 135,000,000.00 </li></ul><ul><li>The scale then continues normally, until 144,000,000.00 </li></ul><ul><li>Because there are 3 pictures of women to one of men, it makes it seem that there are 3 women to every one man. </li></ul>
  4. 4. 3D graphs <ul><li>In this graph, 3D bars on the continents of the world to show oil consumption of the it. </li></ul><ul><li>Because the graph is on a spherical base, we cannot properly perceive how high each bar is. </li></ul>
  5. 5. Denial of Information <ul><li>In this graph, we can see that smoking is the largest cause of death in the United States. </li></ul><ul><li>But things like heart diseases, or in fact, any diseases except AIDS, are not represented in the graph. </li></ul>
  6. 6. 1D -> 2D <ul><li>In this graph, one dimensional information, number of doctors, is represented in a two dimensional space, the size of the doctor. </li></ul><ul><li>This makes it seem as though each jump is extremely large, w he n in fact, it is not. </li></ul>
  7. 7. Changing Scales <ul><li>Look at the scale used. </li></ul><ul><li>It is changed along the way. </li></ul><ul><li>O ne unit for the last few lines, are around 5 or 6 units of the first. </li></ul>
  8. 8. Credits <ul><li>PowerPoint – Emmanuel Kwok </li></ul><ul><li>Images – Thomas Chen </li></ul><ul><li>Analysis – Emmanuel Kwok and Thomas Chen. </li></ul>
