Transcript of "Measures of central tendency"

  1. 1. Measures of Central Tendency<br />By Tyler Torek<br />Statistics<br />
  2. 2. Four Measures of Central Tendency<br /><ul><li>Mean
  3. 3. Median
  4. 4. Mode
  5. 5. Range</li></ul>These measures help describe data.<br />
  6. 6. Mean<br />the of a set of the data<br />average<br />3, 4, 4, 10, 15, 16, 18<br />70  7 =<br />10<br />Just<br />add and divide<br />
  7. 7. Median<br />the number<br />middle<br />3, 4, 4, , 15, 16, 18<br />10<br />10 is the median<br />Justfind the middle<br />
  8. 8. Median<br />numbers not in sequence must be ordered<br />6, 12, 2, 6, 4<br />2, 4, , 6, 12<br />6<br />6 is the median<br />
  9. 9. Mode<br />the number that repeats the <br />most<br />3, 4, 4, 10, 15, 16, 18<br />4 is the mode<br />The number that appears the most<br />
  10. 10. Mode<br />there may be more than one mode<br />3, 3, 4, 4, 4, 7, 9, 9, 9<br />4 & 9 are the modes<br />
  11. 11. Range<br />the difference between the and<br />least greatest<br />, 4, 4, 10, 15, 16, <br />3 18 <br />18 – 3 = 15<br />Just subtract largest and smallest<br />
  12. 12. Find the all four measures of central tendency below.<br />1, 1, 3, 7, 11, 13, 20<br />Mode<br />56  7 = 8<br />Median<br />Mean<br />20 – 1 = 19<br />Practice<br />Range<br />
