Across
  1. 3. A value that "lies outside" (is much smaller or larger than) most of the other values in a set of data.
  2. 7. the average of the numbers: a calculated "central" value of a set of numbers.
  3. 8. The smallest value.
  4. 11. A special type of diagram showing Quartiles 1, 2 and 3 (where the data can be split into quarters) in a box, with lines extending to the lowest and highest values.
  5. 12. A measure of central tendency (measure of center) is a value that attempts to describe a set of data by identifying the central position of the data set.
  6. 14. (Q3) is the middle value between the median and the highest value of the data set.
  7. 15. The difference between the lowest and highest values.
Down
  1. 1. The range from Quartile 1 to Quartile 3: Q3 − Q1(Quartiles are the values that divide a list of numbers into quarters.)(IQR)
  2. 2. (Q1) is defined as the middle number between the smallest number and the median of the data set
  3. 4. Events that can't happen at the same time.
  4. 5. Measures of spread describe how similar or varied the set of observed values are for a particular variable (data item).
  5. 6. A plot where each data value is split into a "leaf" (usually the last digit) and a "stem" (the other digits).
  6. 7. The "middle" of a sorted list of numbers.
  7. 9. The number which appears most often in a set of numbers.
  8. 10. A graphical display where the data is grouped into ranges (such as "100 to 149", "150 to 199", etc), and then plotted as bars.
  9. 12. The largest value.
  10. 13. How often something happens (usually during a period of time).
