  2. 3. A description of data that has the normal curve as its graph.
  3. 7. A ________ distribution is a table that lists each piece of data in the set and the frequency, or the number of times that it appears in the data set.
  4. 14. Mathematics that deals with the collection, analysis, and interpretation of data.

  9. 25. A _____ plot is a graph that shows bivariate data using points on a graph.
  10. 27. Single numbers that are used to represent the range of the numbers in a given data set; also called a spread.

  1. 2. A relationship between two variables.
  2. 4. The most often occurring value in a data set; there can be more than one mode or no modes at all.
  3. 5. A person’s income before all taxes are deducted.
  4. 6. A _____ correlation exists if the value of one variable increases when the value of the other variable increases.
  5. 8. The relative ______ frequency is the ratio of the cumulative frequency of a particular interval to the total number of pieces of data collected.
  6. 9. An association between two variables.
  7. 10. The actual numbers that, without any reference, are tricky to try and interpret are refered to as the _____ data.
  8. 11. Expense for goods or services that are nonessential.
  9. 12. A set of numbers.
  10. 13. Often referred to as average; the sum of all the numbers in a data set divided by the number of elements in the data set.
  11. 15. The square root of the variance which is a measure of dispersion is known as the _______ deviation.
  12. 17. _____ curve is another name for the normal curve because it is shaped like a _____.
  13. 18. A _____ correlation exists if the value of one variable decreases when the value of the other variable increases.
  14. 20. The mean _______ deviation is A statistic that takes the absolute value of each number’s deviation from the mean and averages those absolute values.
  15. 21. A statistical measure used to compare data that indicates what percent of the total frequency total appears at or below a particular number.
  16. 24. When the ends of a plotted curve move away from the mean, they get closer and closer to the horizontal axis but never touch it.
  17. 26. A score that uses the standard deviation as a unit of measure of deviation from the mean; also called a standard score.
  18. 29. A ______ curve is a commonly used bell-shaped graph in statistics in which areas under the curves represent percents of data in specified intervals.
  19. 30. Determined when statisticians square each deviation from the mean, and find the average of these squared deviations.
