- 23. A set of data that has two modes.
- 25. A _____ plot is a graph that shows bivariate data using points on a graph.
- 27. Single numbers that are used to represent the range of the numbers in a given data set; also called a spread.
- 28. The middle number when numbers are in ascending or descending order.

- 2. A relationship between two variables.
- 4. The most often occurring value in a data set; there can be more than one mode or no modes at all.
- 5. A person’s income before all taxes are deducted.
- 6. A _____ correlation exists if the value of one variable increases when the value of the other variable increases.
- 8. The relative ______ frequency is the ratio of the cumulative frequency of a particular interval to the total number of pieces of data collected.
- 9. An association between two variables.
- 10. The actual numbers that, without any reference, are tricky to try and interpret are refered to as the _____ data.
- 11. Expense for goods or services that are nonessential.
- 12. A set of numbers.
- 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.
- 15. The square root of the variance which is a measure of dispersion is known as the _______ deviation.
- 17. _____ curve is another name for the normal curve because it is shaped like a _____.
- 18. A _____ correlation exists if the value of one variable decreases when the value of the other variable increases.
- 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.
- 21. A statistical measure used to compare data that indicates what percent of the total frequency total appears at or below a particular number.
- 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.
- 26. A score that uses the standard deviation as a unit of measure of deviation from the mean; also called a standard score.
- 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.
- 30. Determined when statisticians square each deviation from the mean, and find the average of these squared deviations.
