Across
  1. 1. three values that divide a set of data into four intervals with equal numbers of data
  2. 4. the x-intercepts of a quadratic relation. the value of x when y = 0
  3. 6. a binomial of the form x^2-r^2. the factors of a difference of squares are (x-r)(x+r)
  4. 9. the longest side of a right triangle. the side across the right angle
  5. 10. data that are distinct and can be counted, ex the number of students who like rice
  6. 13. the sum of values in a set of data divided by the number of values in the set of data
  7. 14. the difference between the greatest and the least values in a set of data
  8. 15. an extreme value in a set of data. the value is "far away" from the others
Down
  1. 2. means 'triangle measurement.' used to calculate lengths of sides and measures of angles in triangles
  2. 3. the middle value when data is ordered from least to greatest
  3. 5. quadratic relation y=a(x-h)^2 + k
  4. 7. the length of time for which interest is calculated before being accumulated
  5. 8. the side that forms one of the arms of the angle being considered in a right triangle, but is not the the hypotenuse
  6. 11. a group of individuals or items that are representative of the population from which they are taken
  7. 12. a set of outcomes with the same results
