  1. Chapter 2Statistics and Data Analysis Vocabulary

  2. Bar graph p. 73 Definition: A graph that compares data by using bars of different lengths and heights to show the values. Example:

  3. data p. 73 Definition: Numbers or symbols, sometimes collected from a survey or experiment, to show information. Example:

  4. frequency p. 73 Definition: The number of times a result occurs or something happens in a set amount of time or collection of data. Example: Frequencies

  5. graph p. 73 Definition: A visual way to display data. Example:

  6. histogram p. 83 Definition: A graph that uses bars to show frequency of data organized in intervals. Example:

  7. x-axis (Horizontal axis) p. 73 Definition: The axis in a coordinate plane that runs left and right. Example:

  8. Line graph • 73 Definition: A graph that uses points connected by line segments to represent data. Example:

  9. Line plot p. 87 Definition: A graph that uses columns of Xs above a number line to show frequency of data. Example:

  10. Negative number p. 113 Definition: A number that is less than zero. Example: -2 -10.5 -125.234

  11. Positive number p. 113 Definition: A number that is greater than zero. Example: 1 34.5 125.3786

  12. range p. 100 Definition: The difference between the greatest and the least numbers in a set of data. Example: highest temp: 104 lowest temp: 64 range: 104 - 64 = 40

  13. y-axis (Vertical axis) p. 73 Definition: A vertical number line on a graph. Example:

  14. integers p. 113 Definition: Positive whole numbers, their opposites (negative whole numbers), and zero Example:

  15. Mean (average) p. 95 Definition: the sum of the data divided by the number of pieces of data Example: data: 64; 70; 56; 58; 60; 70 64 + 70 + 56 + 58 + 60 + 70 6 = 378 = 63 6

  16. median p. 99 Definition: In a data set that has been ordered from least to greatest, the median is the middle number if there is an odd number of data items. If there is an even number of data items, it is the mean of the 2 middle numbers. Example: data: 64; 70; 56; 58; 60; 70 Median: 56, 58, 60, 64, 70, 70 60 + 64 = 124 = 62 2 2

  17. mode p. 99 Definition: The number or numbers that occur most often in a data set. Example: data: 64; 70; 56; 58; 60; 70 MODE: 70
