  2. 6. supposed to show how the values in the data set are distributed
  3. 8. the average of the numbers
  4. 9. the middle value of a set of numbers
  5. 11. all the intervals have approximately equal frequencies
  6. 14. no correlation is show (points show no trend)
  7. 15. a relationship between two events where one event is affected by the other

Down
  1. 1. a piece of data that is very far away from the other values in the data set
  2. 2. a type of bar graph that displays frequencies
  3. 4. a complete group
  4. 5. diagrams made of overlapping circles that is used to show relationships between groups
  5. 7. a histogram whose vertical axis shows the fraction or percent of the data values in each interval
  6. 10. the number you get after subtracting Q1 from Q3
