Across
  1. 1. A measure of how spread out data values are from the mean.
  2. 5. The difference between the upper and lower quartiles.
  3. 7. A distribution with a long tail extending to the left; most data values are on the higher end.
  4. 11. A graph that uses points to show the relationship between two numerical variables.
  5. 14. The average of a set of data values; found by adding all values and dividing by the number of values.
  6. 16. (Q3): The median of the upper half of an ordered data set.
  7. 19. A relationship in which one variable tends to decrease as the other increases.
  8. 20. A symmetric, bell-shaped distribution centered around the mean.
  9. 21. The difference between the maximum and minimum values.
  10. 22. The smallest value in a data set.
Down
  1. 2. A table that displays the relationship between two categorical variables.
  2. 3. A distribution with a long tail extending to the right; most data values are on the lower end.
  3. 4. A situation in which there is no apparent association between two variables.
  4. 6. The proportion or percentage of observations in a category.
  5. 8. A relationship in which one variable tends to increase as the other increases.
  6. 9. (MAD): The average distance of each data value from the mean.
  7. 10. A graph that displays the five-number summary (minimum, Q1, median, Q3, maximum) of a data set.
  8. 12. (Q1): The median of the lower half of an ordered data set.
  9. 13. The square of the standard deviation.
  10. 14. The value or values that occur most frequently in a data set.
  11. 15. The middle value in an ordered data set. If there are two middle values, the median is their average.
  12. 17. The largest value in a data set.
  13. 18. A graph that uses bars to show the frequency of data within intervals.
